8 All configurable data is placed in :file:`config.inc.php` in phpMyAdmin's
9 toplevel directory. If this file does not exist, please refer to the
10 :ref:`setup` section to create one. This file only needs to contain the
11 parameters you want to change from their corresponding default value in
12 :file:`libraries/config.default.php` (this file is not intended for changes).
16 :ref:`config-examples` for examples of configurations
18 If a directive is missing from your file, you can just add another line with
19 the file. This file is for over-writing the defaults; if you wish to use the
20 default value there's no need to add a line here.
22 The parameters which relate to design (like colors) are placed in
23 :file:`themes/themename/scss/_variables.scss`. You might also want to create
24 :file:`config.footer.inc.php` and :file:`config.header.inc.php` files to add
25 your site specific code to be included on start and end of each page.
29 Some distributions (eg. Debian or Ubuntu) store :file:`config.inc.php` in
30 ``/etc/phpmyadmin`` instead of within phpMyAdmin sources.
35 .. config:option:: $cfg['PmaAbsoluteUri']
40 .. versionchanged:: 4.6.5
42 This setting was not available in phpMyAdmin 4.6.0 - 4.6.4.
44 Sets here the complete :term:`URL` (with full path) to your phpMyAdmin
45 installation's directory. E.g.
46 ``https://www.example.net/path_to_your_phpMyAdmin_directory/``. Note also
47 that the :term:`URL` on most of web servers are case sensitive (even on
48 Windows). Don’t forget the trailing slash at the end.
50 Starting with version 2.3.0, it is advisable to try leaving this blank. In
51 most cases phpMyAdmin automatically detects the proper setting. Users of
52 port forwarding or complex reverse proxy setup might need to set this.
54 A good test is to browse a table, edit a row and save it. There should be
55 an error message if phpMyAdmin is having trouble auto–detecting the correct
56 value. If you get an error that this must be set or if the autodetect code
57 fails to detect your path, please post a bug report on our bug tracker so
58 we can improve the code.

62 .. config:option:: $cfg['PmaNoRelation_DisableWarning']
67 Starting with version 2.3.0 phpMyAdmin offers a lot of features to
68 work with master / foreign – tables (see :config:option:`$cfg['Servers'][$i]['pmadb']`).
70 If you tried to set this
71 up and it does not work for you, have a look on the :guilabel:`Structure` page
72 of one database where you would like to use it. You will find a link
73 that will analyze why those features have been disabled.
75 If you do not want to use those features set this variable to ``true`` to
76 stop this message from appearing.
78 .. config:option:: $cfg['AuthLog']
83 .. versionadded:: 4.8.0
85 This is supported since phpMyAdmin 4.8.0.
87 Configure authentication logging destination. Failed (or all, depending on
88 :config:option:`$cfg['AuthLogSuccess']`) authentication attempts will be
89 logged according to this directive:
92 Let phpMyAdmin automatically choose between ``syslog`` and ``php``.
94 Log using syslog, using AUTH facility, on most systems this ends up
95 in :file:`/var/log/auth.log`.
97 Log into PHP error log.
99 Log into PHP SAPI logging.
101 Any other value is treated as a filename and log entries are written there.
105 When logging to a file, make sure its permissions are correctly set

126 A warning is displayed on the main page if Suhosin is detected.
128 You can set this parameter to ``true`` to stop this message from appearing.
130 .. config:option:: $cfg['LoginCookieValidityDisableWarning']
135 A warning is displayed on the main page if the PHP parameter
136 session.gc_maxlifetime is lower than cookie validity configured in phpMyAdmin.
138 You can set this parameter to ``true`` to stop this message from appearing.
140 .. config:option:: $cfg['ServerLibraryDifference_DisableWarning']
145 .. deprecated:: 4.7.0
147 This setting was removed as the warning has been removed as well.
149 A warning is displayed on the main page if there is a difference
150 between the MySQL library and server version.
152 You can set this parameter to ``true`` to stop this message from appearing.
154 .. config:option:: $cfg['ReservedWordDisableWarning']
159 This warning is displayed on the Structure page of a table if one or more
160 column names match with words which are MySQL reserved.
162 If you want to turn off this warning, you can set it to ``true`` and
163 warning will no longer be displayed.
165 .. config:option:: $cfg['TranslationWarningThreshold']
170 Show warning about incomplete translations on certain threshold.
172 .. config:option:: $cfg['SendErrorReports']
183 Sets the default behavior for JavaScript error reporting.
185 Whenever an error is detected in the JavaScript execution, an error report
186 may be sent to the phpMyAdmin team if the user agrees.
188 The default setting of ``'ask'`` will ask the user everytime there is a new
189 error report. However you can set this parameter to ``'always'`` to send error
190 reports without asking for confirmation or you can set it to ``'never'`` to
191 never send error reports.
193 This directive is available both in the configuration file and in users
194 preferences. If the person in charge of a multi-user installation prefers
195 to disable this feature for all users, a value of ``'never'`` should be
196 set, and the :config:option:`$cfg['UserprefsDisallow']` directive should
197 contain ``'SendErrorReports'`` in one of its array values.
199 .. config:option:: $cfg['ConsoleEnterExecutes']
204 Setting this to ``true`` allows the user to execute queries by pressing Enter
205 instead of Ctrl+Enter. A new line can be inserted by pressing Shift+Enter.
207 The behaviour of the console can be temporarily changed using console's
210 .. config:option:: $cfg['AllowThirdPartyFraming']
212 :type: boolean|string
215 Setting this to ``true`` allows phpMyAdmin to be included inside a frame,
216 and is a potential security hole allowing cross-frame scripting attacks or
217 clickjacking. Setting this to 'sameorigin' prevents phpMyAdmin to be
218 included from another document in a frame, unless that document belongs
221 Server connection settings
222 --------------------------
224 .. config:option:: $cfg['Servers']
227 :default: one server array with settings listed below
229 Since version 1.4.2, phpMyAdmin supports the administration of multiple
230 MySQL servers. Therefore, a :config:option:`$cfg['Servers']`-array has been
231 added which contains the login information for the different servers. The
232 first :config:option:`$cfg['Servers'][$i]['host']` contains the hostname of
233 the first server, the second :config:option:`$cfg['Servers'][$i]['host']`
234 the hostname of the second server, etc. In
235 :file:`libraries/config.default.php`, there is only one section for server
236 definition, however you can put as many as you need in
237 :file:`config.inc.php`, copy that block or needed parts (you don't have to
238 define all settings, just those you need to change).
242 The :config:option:`$cfg['Servers']` array starts with
243 $cfg['Servers'][1]. Do not use $cfg['Servers'][0]. If you want more
244 than one server, just copy following section (including $i
245 increment) several times. There is no need to define full server
246 array, just define values you need to change.
248 .. config:option:: $cfg['Servers'][$i]['host']
251 :default: ``'localhost'``
253 The hostname or :term:`IP` address of your $i-th MySQL-server. E.g.
258 * hostname, e.g., ``'localhost'`` or ``'mydb.example.org'``
259 * IP address, e.g., ``'127.0.0.1'`` or ``'192.168.10.1'``
260 * IPv6 address, e.g. ``2001:cdba:0000:0000:0000:0000:3257:9652``
261 * dot - ``'.'``, i.e., use named pipes on windows systems
262 * empty - ``''``, disables this server
266 The hostname ``localhost`` is handled specially by MySQL and it uses
267 the socket based connection protocol. To use TCP/IP networking, use an
268 IP address or hostname such as ``127.0.0.1`` or ``db.example.com``. You
269 can configure the path to the socket with
270 :config:option:`$cfg['Servers'][$i]['socket']`.
274 :config:option:`$cfg['Servers'][$i]['port']`,
275 <https://dev.mysql.com/doc/refman/8.0/en/connecting.html>
277 .. config:option:: $cfg['Servers'][$i]['port']
282 The port-number of your $i-th MySQL-server. Default is 3306 (leave
287 If you use ``localhost`` as the hostname, MySQL ignores this port number
288 and connects with the socket, so if you want to connect to a port
289 different from the default port, use ``127.0.0.1`` or the real hostname
290 in :config:option:`$cfg['Servers'][$i]['host']`.
294 :config:option:`$cfg['Servers'][$i]['host']`,
295 <https://dev.mysql.com/doc/refman/8.0/en/connecting.html>
297 .. config:option:: $cfg['Servers'][$i]['socket']
302 The path to the socket to use. Leave blank for default. To determine
303 the correct socket, check your MySQL configuration or, using the
304 :command:`mysql` command–line client, issue the ``status`` command. Among the
305 resulting information displayed will be the socket used.
309 This takes effect only if :config:option:`$cfg['Servers'][$i]['host']` is set

322 Whether to enable SSL for the connection between phpMyAdmin and the MySQL
323 server to secure the connection.
325 When using the ``'mysql'`` extension,
326 none of the remaining ``'ssl...'`` configuration options apply.

445 .. config:option:: $cfg['Servers'][$i]['ssl_verify']
450 .. versionadded:: 4.6.0
452 This is supported since phpMyAdmin 4.6.0.
454 If your PHP install uses the MySQL Native Driver (mysqlnd), your
455 MySQL server is 5.6 or later, and your SSL certificate is self-signed,
456 there is a chance your SSL connection will fail due to validation.
457 Setting this to ``false`` will disable the validation check.
459 Since PHP 5.6.0 it also verifies whether server name matches CN of its
460 certificate. There is currently no way to disable just this check without
461 disabling complete SSL verification.
465 Disabling the certificate verification defeats purpose of using SSL.
466 This will make the connection vulnerable to man in the middle attacks.

490 .. deprecated:: 4.7.0
492 This setting is no longer used as of 4.7.0, since MySQL decides the
493 connection type based on host, so it could lead to unexpected results.
494 Please set :config:option:`$cfg['Servers'][$i]['host']` accordingly
497 What type connection to use with the MySQL server. Your options are
498 ``'socket'`` and ``'tcp'``. It defaults to tcp as that is nearly guaranteed
499 to be available on all MySQL servers, while sockets are not supported on
500 some platforms. To use the socket mode, your MySQL server must be on the
501 same machine as the Web server.

548 This special account is used to access :ref:`linked-tables`.
549 You don't need it in single user case, but if phpMyAdmin is shared it
550 is recommended to give access to :ref:`linked-tables` only to this user
551 and configure phpMyAdmin to use it. All users will then be able to use
552 the features without need to have direct access to :ref:`linked-tables`.

607 Whether config or cookie or :term:`HTTP` or signon authentication should be
608 used for this server.
610 * 'config' authentication (``$auth_type = 'config'``) is the plain old
611 way: username and password are stored in :file:`config.inc.php`.
612 * 'cookie' authentication mode (``$auth_type = 'cookie'``) allows you to
613 log in as any valid MySQL user with the help of cookies.
614 * 'http' authentication allows you to log in as any
615 valid MySQL user via HTTP-Auth.
616 * 'signon' authentication mode (``$auth_type = 'signon'``) allows you to
617 log in from prepared PHP session data or using supplied PHP script.

665 When using :config:option:`$cfg['Servers'][$i]['auth_type']` set to
666 'config', this is the user/password-pair which phpMyAdmin will use to
667 connect to the MySQL server. This user/password pair is not needed when

672 .. config:option:: $cfg['Servers'][$i]['nopassword']
677 .. deprecated:: 4.7.0
679 This setting was removed as it can produce unexpected results.
681 Allow attempt to log in without password when a login with password
682 fails. This can be used together with http authentication, when
683 authentication is done some other way and phpMyAdmin gets user name
684 from auth and uses empty password for connecting to MySQL. Password
685 login is still tried first, but as fallback, no password method is

691 :type: string or array
694 If set to a (an array of) database name(s), only this (these)
695 database(s) will be shown to the user. Since phpMyAdmin 2.2.1,
696 this/these database(s) name(s) may contain MySQL wildcards characters
697 ("\_" and "%"): if you want to use literal instances of these
698 characters, escape them (I.E. use ``'my\_db'`` and not ``'my_db'``).
700 This setting is an efficient way to lower the server load since the
701 latter does not need to send MySQL requests to build the available
702 database list. But **it does not replace the privileges rules of the
703 MySQL database server**. If set, it just means only these databases
704 will be displayed but **not that all other databases can't be used.**

713 Previous versions permitted to specify the display order of
714 the database names via this directive.
716 .. config:option:: $cfg['Servers'][$i]['hide_db']
721 Regular expression for hiding some databases from unprivileged users.
722 This only hides them from listing, but a user is still able to access
723 them (using, for example, the SQL query area). To limit access, use
724 the MySQL privilege system. For example, to hide all databases
725 starting with the letter "a", use
729 $cfg['Servers'][$i]['hide_db'] = '^a';
731 and to hide both "db1" and "db2" use
735 $cfg['Servers'][$i]['hide_db'] = '^(db1|db2)$';
737 More information on regular expressions can be found in the `PCRE

740 of the PHP reference manual.
742 .. config:option:: $cfg['Servers'][$i]['verbose']
747 Only useful when using phpMyAdmin with multiple server entries. If
748 set, this string will be displayed instead of the hostname in the
749 pull-down menu on the main page. This can be useful if you want to
750 show only certain databases on your system, for example. For HTTP
751 auth, all non-US-ASCII characters will be stripped.

794 Since release 2.2.0 phpMyAdmin allows users to bookmark queries. This
795 can be useful for queries you often run. To allow the usage of this
798 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
799 * enter the table name in :config:option:`$cfg['Servers'][$i]['bookmarktable']`
801 This feature can be disabled by setting the configuration to ``false``.
804 .. config:option:: $cfg['Servers'][$i]['relation']
806 :type: string or false
809 .. versionadded:: 2.2.4
811 Since release 2.2.4 you can describe, in a special 'relation' table,
812 which column is a key in another table (a foreign key). phpMyAdmin
813 currently uses this to:
815 * make clickable, when you browse the master table, the data values that
816 point to the foreign table;
817 * display in an optional tool-tip the "display column" when browsing the
818 master table, if you move the mouse to a column containing a foreign
819 key (use also the 'table\_info' table); (see :ref:`faqdisplay`)
820 * in edit/insert mode, display a drop-down list of possible foreign keys
821 (key value and "display column" are shown) (see :ref:`faq6_21`)
822 * display links on the table properties page, to check referential
823 integrity (display missing foreign keys) for each described key;
824 * in query-by-example, create automatic joins (see :ref:`faq6_6`)
825 * enable you to get a :term:`PDF` schema of
826 your database (also uses the table\_coords table).
828 The keys can be numeric or character.
830 To allow the usage of this functionality:
832 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
833 * put the relation table name in :config:option:`$cfg['Servers'][$i]['relation']`
834 * now as normal user open phpMyAdmin and for each one of your tables
835 where you want to use this feature, click :guilabel:`Structure/Relation view/`
836 and choose foreign columns.
838 This feature can be disabled by setting the configuration to ``false``.
842 In the current version, ``master_db`` must be the same as ``foreign_db``.
843 Those columns have been put in future development of the cross-db
847 .. config:option:: $cfg['Servers'][$i]['table_info']
849 :type: string or false
852 .. versionadded:: 2.3.0
854 Since release 2.3.0 you can describe, in a special 'table\_info'
855 table, which column is to be displayed as a tool-tip when moving the
856 cursor over the corresponding key. This configuration variable will
857 hold the name of this special table. To allow the usage of this
860 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
861 * put the table name in :config:option:`$cfg['Servers'][$i]['table\_info']` (e.g.
863 * then for each table where you want to use this feature, click

872 .. config:option:: $cfg['Servers'][$i]['table_coords']
874 :type: string or false
877 The designer feature can save your page layout; by pressing the "Save page" or "Save page as"
878 button in the expanding designer menu, you can customize the layout and have it loaded the next
879 time you use the designer. That layout is stored in this table. Furthermore, this table is also
880 required for using the PDF relation export feature, see
881 :config:option:`$cfg['Servers'][$i]['pdf\_pages']` for additional details.
883 .. config:option:: $cfg['Servers'][$i]['pdf_pages']
885 :type: string or false
888 .. versionadded:: 2.3.0
890 Since release 2.3.0 you can have phpMyAdmin create :term:`PDF` pages
891 showing the relations between your tables. Further, the designer interface
892 permits visually managing the relations. To do this it needs two tables
893 "pdf\_pages" (storing information about the available :term:`PDF` pages)
894 and "table\_coords" (storing coordinates where each table will be placed on
895 a :term:`PDF` schema output). You must be using the "relation" feature.
897 To allow the usage of this functionality:
899 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
900 * put the correct table names in
901 :config:option:`$cfg['Servers'][$i]['table\_coords']` and
902 :config:option:`$cfg['Servers'][$i]['pdf\_pages']`
904 This feature can be disabled by setting either of the configurations to ``false``.
906 .. seealso:: :ref:`faqpdf`.
909 .. config:option:: $cfg['Servers'][$i]['designer_coords']
914 .. versionadded:: 2.10.0
916 Since release 2.10.0 a Designer interface is available; it permits to
917 visually manage the relations.
919 .. deprecated:: 4.3.0
921 This setting was removed and the Designer table positioning data is now stored into :config:option:`$cfg['Servers'][$i]['table\_coords']`.
924 You can now delete the table `pma__designer_coords` from your phpMyAdmin configuration storage database and remove :config:option:`$cfg['Servers'][$i]['designer\_coords']` from your configuration file.
927 .. config:option:: $cfg['Servers'][$i]['column_info']
929 :type: string or false
932 .. versionadded:: 2.3.0
934 This part requires a content update! Since release 2.3.0 you can
935 store comments to describe each column for each table. These will then
936 be shown on the "printview".
938 Starting with release 2.5.0, comments are consequently used on the table
939 property pages and table browse view, showing up as tool-tips above the
940 column name (properties page) or embedded within the header of table in
941 browse view. They can also be shown in a table dump. Please see the
942 relevant configuration directives later on.
944 Also new in release 2.5.0 is a MIME- transformation system which is also
945 based on the following table structure. See :ref:`transformations` for
946 further information. To use the MIME- transformation system, your
947 column\_info table has to have the three new columns 'mimetype',
948 'transformation', 'transformation\_options'.
950 Starting with release 4.3.0, a new input-oriented transformation system
951 has been introduced. Also, backward compatibility code used in the old
952 transformations system was removed. As a result, an update to column\_info
953 table is necessary for previous transformations and the new input-oriented
954 transformation system to work. phpMyAdmin will upgrade it automatically
955 for you by analyzing your current column\_info table structure.
956 However, if something goes wrong with the auto-upgrade then you can
957 use the SQL script found in ``./sql/upgrade_column_info_4_3_0+.sql``
958 to upgrade it manually.
960 To allow the usage of this functionality:
962 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
963 * put the table name in :config:option:`$cfg['Servers'][$i]['column\_info']` (e.g.
964 ``pma__column_info``)
965 * to update your PRE-2.5.0 Column\_comments table use this: and
966 remember that the Variable in :file:`config.inc.php` has been renamed from
967 :samp:`$cfg['Servers'][$i]['column\_comments']` to
968 :config:option:`$cfg['Servers'][$i]['column\_info']`
970 .. code-block:: mysql
972 ALTER TABLE `pma__column_comments`
973 ADD `mimetype` VARCHAR( 255 ) NOT NULL,
974 ADD `transformation` VARCHAR( 255 ) NOT NULL,
975 ADD `transformation_options` VARCHAR( 255 ) NOT NULL;
976 * to update your PRE-4.3.0 Column\_info table manually use this
977 ``./sql/upgrade_column_info_4_3_0+.sql`` SQL script.
979 This feature can be disabled by setting the configuration to ``false``.
983 For auto-upgrade functionality to work, your
984 :config:option:`$cfg['Servers'][$i]['controluser']` must have ALTER privilege on
985 ``phpmyadmin`` database. See the `MySQL documentation for GRANT
986 <https://dev.mysql.com/doc/refman/8.0/en/grant.html>`_ on how to
987 ``GRANT`` privileges to a user.
990 .. config:option:: $cfg['Servers'][$i]['history']
992 :type: string or false
995 .. versionadded:: 2.5.0
997 Since release 2.5.0 you can store your :term:`SQL` history, which means all
998 queries you entered manually into the phpMyAdmin interface. If you don't
999 want to use a table-based history, you can use the JavaScript-based
1002 Using that, all your history items are deleted when closing the window.
1003 Using :config:option:`$cfg['QueryHistoryMax']` you can specify an amount of
1004 history items you want to have on hold. On every login, this list gets cut
1005 to the maximum amount.
1007 The query history is only available if JavaScript is enabled in
1010 To allow the usage of this functionality:
1012 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage

1024 .. versionadded:: 3.5.0
1026 Since release 3.5.0 you can show recently used tables in the
1027 navigation panel. It helps you to jump across table directly, without
1028 the need to select the database, and then select the table. Using
1029 :config:option:`$cfg['NumRecentTables']` you can configure the maximum number
1030 of recent tables shown. When you select a table from the list, it will jump to
1031 the page specified in :config:option:`$cfg['NavigationTreeDefaultTabTable']`.
1033 Without configuring the storage, you can still access the recently used tables,
1034 but it will disappear after you logout.
1036 To allow the usage of this functionality persistently:
1038 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
1039 * put the table name in :config:option:`$cfg['Servers'][$i]['recent']` (e.g.

1052 Since release 4.2.0 you can show a list of selected tables in the
1053 navigation panel. It helps you to jump to the table directly, without
1054 the need to select the database, and then select the table. When you
1055 select a table from the list, it will jump to the page specified in
1056 :config:option:`$cfg['NavigationTreeDefaultTabTable']`.
1058 You can add tables to this list or remove tables from it in database
1059 structure page by clicking on the star icons next to table names. Using
1060 :config:option:`$cfg['NumFavoriteTables']` you can configure the maximum
1061 number of favorite tables shown.
1063 Without configuring the storage, you can still access the favorite tables,

1077 :type: string or false
1080 .. versionadded:: 3.5.0
1082 Since release 3.5.0 phpMyAdmin can be configured to remember several
1083 things (sorted column :config:option:`$cfg['RememberSorting']`, column order,
1084 and column visibility from a database table) for browsing tables. Without
1085 configuring the storage, these features still can be used, but the values will
1086 disappear after you logout.
1088 To allow the usage of these functionality persistently:
1090 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage

1105 .. config:option:: $cfg['Servers'][$i]['usergroups']
1107 :type: string or false
1110 .. versionadded:: 4.1.0
1112 Since release 4.1.0 you can create different user groups with menu items
1113 attached to them. Users can be assigned to these groups and the logged in
1114 user would only see menu items configured to the usergroup they are assigned to.
1115 To do this it needs two tables "usergroups" (storing allowed menu items for each
1116 user group) and "users" (storing users and their assignments to user groups).
1118 To allow the usage of this functionality:
1120 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage

1155 Since release 4.3.0 you can have a central list of columns per database.
1156 You can add/remove columns to the list as per your requirement. These columns
1157 in the central list will be available to use while you create a new column for
1158 a table or create a table itself. You can select a column from central list
1159 while creating a new column, it will save you from writing the same column definition
1160 over again or from writing different names for similar column.
1162 To allow the usage of this functionality:
1164 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
1165 * put the table name in :config:option:`$cfg['Servers'][$i]['central_columns']` (e.g.

1232 .. versionadded:: 3.3.x
1234 Since release 3.3.x a tracking mechanism is available. It helps you to
1235 track every :term:`SQL` command which is
1236 executed by phpMyAdmin. The mechanism supports logging of data
1237 manipulation and data definition statements. After enabling it you can
1238 create versions of tables.
1240 The creation of a version has two effects:
1242 * phpMyAdmin saves a snapshot of the table, including structure and
1244 * phpMyAdmin logs all commands which change the structure and/or data of
1245 the table and links these commands with the version number.
1247 Of course you can view the tracked changes. On the :guilabel:`Tracking`
1248 page a complete report is available for every version. For the report you
1249 can use filters, for example you can get a list of statements within a date
1250 range. When you want to filter usernames you can enter \* for all names or
1251 you enter a list of names separated by ','. In addition you can export the
1252 (filtered) report to a file or to a temporary database.
1254 To allow the usage of this functionality:

1318 :type: string or false
1321 .. versionadded:: 3.4.x
1323 Since release 3.4.x phpMyAdmin allows users to set most preferences by
1324 themselves and store them in the database.
1326 If you don't allow for storing preferences in
1327 :config:option:`$cfg['Servers'][$i]['pmadb']`, users can still personalize
1328 phpMyAdmin, but settings will be saved in browser's local storage, or, it
1329 is is unavailable, until the end of session.
1331 To allow the usage of this functionality:
1333 * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
1334 * put the table name in :config:option:`$cfg['Servers'][$i]['userconfig']`

1346 When tables are dropped or renamed,
1347 :config:option:`$cfg['Servers'][$i]['table_uiprefs']` may contain invalid data
1348 (referring to tables which no longer exist). We only keep this number of newest
1349 rows in :config:option:`$cfg['Servers'][$i]['table_uiprefs']` and automatically

1357 Sets the time zone used by phpMyAdmin. Leave blank to use the time zone of your
1358 database server. Possible values are explained at
1359 https://dev.mysql.com/doc/refman/8.0/en/time-zone-support.html
1361 This is useful when your database server uses a time zone which is different from the
1362 time zone you want to use in phpMyAdmin.
1364 .. config:option:: $cfg['Servers'][$i]['AllowRoot']
1369 Whether to allow root access. This is just a shortcut for the
1370 :config:option:`$cfg['Servers'][$i]['AllowDeny']['rules']` below.
1372 .. config:option:: $cfg['Servers'][$i]['AllowNoPassword']
1377 Whether to allow logins without a password. The default value of
1378 ``false`` for this parameter prevents unintended access to a MySQL
1379 server with was left with an empty password for root or on which an
1380 anonymous (blank) user is defined.
1382 .. _servers_allowdeny_order:
1383 .. config:option:: $cfg['Servers'][$i]['AllowDeny']['order']
1388 If your rule order is empty, then :term:`IP`
1389 authorization is disabled.
1391 If your rule order is set to
1392 ``'deny,allow'`` then the system applies all deny rules followed by
1393 allow rules. Access is allowed by default. Any client which does not
1394 match a Deny command or does match an Allow command will be allowed
1395 access to the server.
1397 If your rule order is set to ``'allow,deny'``
1398 then the system applies all allow rules followed by deny rules. Access
1399 is denied by default. Any client which does not match an Allow
1400 directive or does match a Deny directive will be denied access to the
1403 If your rule order is set to ``'explicit'``, authorization is
1404 performed in a similar fashion to rule order 'deny,allow', with the
1405 added restriction that your host/username combination **must** be
1406 listed in the *allow* rules, and not listed in the *deny* rules. This
1407 is the **most** secure means of using Allow/Deny rules, and was
1408 available in Apache by specifying allow and deny rules without setting

1412 detecting IP address behind proxies.
1414 .. _servers_allowdeny_rules:
1415 .. config:option:: $cfg['Servers'][$i]['AllowDeny']['rules']
1417 :type: array of strings
1420 The general format for the rules is as such:
1422 .. code-block:: none
1424 <'allow' | 'deny'> <username> [from] <ipmask>
1426 If you wish to match all users, it is possible to use a ``'%'`` as a
1427 wildcard in the *username* field.
1429 There are a few shortcuts you can
1430 use in the *ipmask* field as well (please note that those containing
1431 SERVER\_ADDRESS might not be available on all webservers):
1433 .. code-block:: none
1436 'localhost' -> 127.0.0.1/8
1437 'localnetA' -> SERVER_ADDRESS/8
1438 'localnetB' -> SERVER_ADDRESS/16
1439 'localnetC' -> SERVER_ADDRESS/24
1441 Having an empty rule list is equivalent to either using ``'allow %
1442 from all'`` if your rule order is set to ``'deny,allow'`` or ``'deny %
1443 from all'`` if your rule order is set to ``'allow,deny'`` or
1446 For the :term:`IP Address` matching
1447 system, the following work:
1449 * ``xxx.xxx.xxx.xxx`` (an exact :term:`IP Address`)
1450 * ``xxx.xxx.xxx.[yyy-zzz]`` (an :term:`IP Address` range)
1451 * ``xxx.xxx.xxx.xxx/nn`` (CIDR, Classless Inter-Domain Routing type :term:`IP` addresses)
1453 But the following does not work:
1455 * ``xxx.xxx.xxx.xx[yyy-zzz]`` (partial :term:`IP` address range)

1501 .. config:option:: $cfg['Servers'][$i]['SignonScript']
1506 .. versionadded:: 3.5.0
1508 Name of PHP script to be sourced and executed to obtain login
1509 credentials. This is alternative approach to session based single
1510 signon. The script has to provide a function called
1511 ``get_login_credentials`` which returns list of username and
1512 password, accepting single parameter of existing username (can be
1513 empty). See :file:`examples/signon-script.php` for an example:
1515 .. literalinclude:: ../examples/signon-script.php
1518 .. seealso:: :ref:`auth_signon`
1520 .. config:option:: $cfg['Servers'][$i]['SignonSession']
1525 Name of session which will be used for signon authentication method.
1526 You should use something different than ``phpMyAdmin``, because this
1527 is session which phpMyAdmin uses internally. Takes effect only if
1528 :config:option:`$cfg['Servers'][$i]['SignonScript']` is not configured.
1530 .. seealso:: :ref:`auth_signon`
1532 .. config:option:: $cfg['Servers'][$i]['SignonCookieParams']

1537 .. versionadded:: 4.7.0
1539 An associative array of session cookie parameters of other authentication system.
1540 It is not needed if the other system doesn't use session_set_cookie_params().
1541 Keys should include 'lifetime', 'path', 'domain', 'secure' or 'httponly'.
1542 Valid values are mentioned in `session_get_cookie_params <https://www.php.net/manual/en/
1543 function.session-get-cookie-params.php>`_, they should be set to same values as the
1544 other application uses. Takes effect only if

1560 .. config:option:: $cfg['Servers'][$i]['LogoutURL']
1565 :term:`URL` where user will be redirected
1566 after logout (doesn't affect config authentication method). Should be
1567 absolute including protocol.
1569 .. config:option:: $cfg['Servers'][$i]['hide_connection_errors']
1574 .. versionadded:: 4.9.8
1576 Whether to show or hide detailed MySQL/MariaDB connection errors on the login page.
1580 This error message can contain the target database server hostname or IP address,
1581 which may reveal information about your network to an attacker.
1586 .. config:option:: $cfg['DisableShortcutKeys']
1591 You can disable phpMyAdmin shortcut keys by setting :config:option:`$cfg['DisableShortcutKeys']` to false.
1593 .. config:option:: $cfg['ServerDefault']
1598 If you have more than one server configured, you can set
1599 :config:option:`$cfg['ServerDefault']` to any one of them to autoconnect to that
1600 server when phpMyAdmin is started, or set it to 0 to be given a list
1601 of servers without logging in.
1603 If you have only one server configured,
1604 :config:option:`$cfg['ServerDefault']` MUST be set to that server.
1606 .. config:option:: $cfg['VersionCheck']
1611 Enables check for latest versions using JavaScript on the main phpMyAdmin
1612 page or by directly accessing `index.php?route=/version-check`.
1616 This setting can be adjusted by your vendor.
1618 .. config:option:: $cfg['ProxyUrl']
1623 The url of the proxy to be used when phpmyadmin needs to access the outside
1624 internet such as when retrieving the latest version info or submitting error
1625 reports. You need this if the server where phpMyAdmin is installed does not
1626 have direct access to the internet.
1627 The format is: "hostname:portnumber"
1629 .. config:option:: $cfg['ProxyUser']
1634 The username for authenticating with the proxy. By default, no
1635 authentication is performed. If a username is supplied, Basic
1636 Authentication will be performed. No other types of authentication
1637 are currently supported.
1639 .. config:option:: $cfg['ProxyPass']
1644 The password for authenticating with the proxy.

1659 The maximum number of table names to be displayed in the main panel's
1660 list (except on the Export page).
1662 .. config:option:: $cfg['ShowHint']
1667 Whether or not to show hints (for example, hints when hovering over
1670 .. config:option:: $cfg['MaxCharactersInDisplayedSQL']
1675 The maximum number of characters when a :term:`SQL` query is displayed. The
1676 default limit of 1000 should be correct to avoid the display of tons of
1677 hexadecimal codes that represent BLOBs, but some users have real
1678 :term:`SQL` queries that are longer than 1000 characters. Also, if a
1679 query's length exceeds this limit, this query is not saved in the history.
1681 .. config:option:: $cfg['PersistentConnections']
1686 Whether `persistent connections <https://www.php.net/manual/en/features
1687 .persistent-connections.php>`_ should be used or not.
1691 `mysqli documentation for persistent connections <https://www.php.net/manual/en/mysqli.persistconns.php>`_
1693 .. config:option:: $cfg['ForceSSL']
1698 .. deprecated:: 4.6.0
1700 This setting is no longer available since phpMyAdmin 4.6.0. Please
1701 adjust your webserver instead.
1703 Whether to force using https while accessing phpMyAdmin. In a reverse
1704 proxy setup, setting this to ``true`` is not supported.
1708 In some setups (like separate SSL proxy or load balancer) you might
1709 have to set :config:option:`$cfg['PmaAbsoluteUri']` for correct
1712 .. config:option:: $cfg['MysqlSslWarningSafeHosts']
1715 :default: ``['127.0.0.1', 'localhost']``
1717 This search is case-sensitive and will match the exact string only.
1718 If your setup does not use SSL but is safe because you are using a
1719 local connection or private network, you can add your hostname or :term:`IP` to the list.
1720 You can also remove the default entries to only include yours.
1722 This check uses the value of :config:option:`$cfg['Servers'][$i]['host']`.
1724 .. versionadded:: 5.1.0
1726 Example configuration
1730 $cfg['MysqlSslWarningSafeHosts'] = ['127.0.0.1', 'localhost', 'mariadb.local'];
1733 .. config:option:: $cfg['ExecTimeLimit']
1735 :type: integer [number of seconds]
1738 Set the number of seconds a script is allowed to run. If seconds is
1739 set to zero, no time limit is imposed. This setting is used while
1740 importing/exporting dump files but has
1741 no effect when PHP is running in safe mode.
1743 .. config:option:: $cfg['SessionSavePath']
1748 Path for storing session data (`session\_save\_path PHP parameter
1749 <https://www.php.net/session_save_path>`_).
1753 This folder should not be publicly accessible through the webserver,
1754 otherwise you risk leaking private data from your session.
1756 .. config:option:: $cfg['MemoryLimit']
1758 :type: string [number of bytes]
1761 Set the number of bytes a script is allowed to allocate. If set to
1762 ``'-1'``, no limit is imposed. If set to ``'0'``, no change of the
1763 memory limit is attempted and the :file:`php.ini` ``memory_limit`` is
1766 This setting is used while importing/exporting dump files
1767 so you definitely don't want to put here a too low
1768 value. It has no effect when PHP is running in safe mode.
1770 You can also use any string as in :file:`php.ini`, eg. '16M'. Ensure you
1771 don't omit the suffix (16 means 16 bytes!)
1773 .. config:option:: $cfg['SkipLockedTables']
1778 Mark used tables and make it possible to show databases with locked
1779 tables (since MySQL 3.23.30).
1781 .. config:option:: $cfg['ShowSQL']
1786 Defines whether :term:`SQL` queries
1787 generated by phpMyAdmin should be displayed or not.
1789 .. config:option:: $cfg['RetainQueryBox']
1794 Defines whether the :term:`SQL` query box
1795 should be kept displayed after its submission.
1797 .. config:option:: $cfg['CodemirrorEnable']
1802 Defines whether to use a Javascript code editor for SQL query boxes.
1803 CodeMirror provides syntax highlighting and line numbers. However,
1804 middle-clicking for pasting the clipboard contents in some Linux
1805 distributions (such as Ubuntu) is not supported by all browsers.
1807 .. config:option:: $cfg['DefaultForeignKeyChecks']
1810 :default: ``'default'``
1812 Default value of the checkbox for foreign key checks, to disable/enable
1813 foreign key checks for certain queries. The possible values are ``'default'``,
1814 ``'enable'`` or ``'disable'``. If set to ``'default'``, the value of the
1815 MySQL variable ``FOREIGN_KEY_CHECKS`` is used.
1817 .. config:option:: $cfg['AllowUserDropDatabase']
1824 This is not a security measure as there will be always ways to
1825 circumvent this. If you want to prohibit users from dropping databases,
1826 revoke their corresponding DROP privilege.
1828 Defines whether normal users (non-administrator) are allowed to delete
1829 their own database or not. If set as false, the link :guilabel:`Drop
1830 Database` will not be shown, and even a ``DROP DATABASE mydatabase`` will
1831 be rejected. Quite practical for :term:`ISP` 's with many customers.
1833 This limitation of :term:`SQL` queries is not as strict as when using MySQL
1834 privileges. This is due to nature of :term:`SQL` queries which might be
1835 quite complicated. So this choice should be viewed as help to avoid
1836 accidental dropping rather than strict privilege limitation.
1838 .. config:option:: $cfg['Confirm']
1843 Whether a warning ("Are your really sure...") should be displayed when
1844 you're about to lose data.
1846 .. config:option:: $cfg['UseDbSearch']
1851 Define whether the "search string inside database" is enabled or not.
1853 .. config:option:: $cfg['IgnoreMultiSubmitErrors']
1858 Define whether phpMyAdmin will continue executing a multi-query
1859 statement if one of the queries fails. Default is to abort execution.
1861 .. config:option:: $cfg['enable_drag_drop_import']
1866 Whether or not the drag and drop import feature is enabled.
1867 When enabled, a user can drag a file in to their browser and phpMyAdmin will
1868 attempt to import the file.
1870 .. config:option:: $cfg['URLQueryEncryption']
1875 .. versionadded:: 4.9.8
1877 Define whether phpMyAdmin will encrypt sensitive data (like database name
1878 and table name) from the URL query string. Default is to not encrypt the URL
1881 .. config:option:: $cfg['URLQueryEncryptionSecretKey']
1886 .. versionadded:: 4.9.8
1888 A secret key used to encrypt/decrypt the URL query string.
1889 Should be 32 bytes long.
1891 .. seealso:: :ref:`faq2_10`
1893 Cookie authentication options
1894 -----------------------------
1896 .. config:option:: $cfg['blowfish_secret']
1901 The "cookie" auth\_type uses the :term:`Sodium` extension to encrypt the cookies (see :term:`Cookie`). If you are
1902 using the "cookie" auth\_type, enter here a generated string of random bytes to be used as an encryption key. It
1903 will be used internally by the :term:`Sodium` extension: you won't be prompted for this encryption key.
1905 Since a binary string is usually not printable, it can be converted into a hexadecimal representation (using a
1906 function like `sodium_bin2hex <https://www.php.net/sodium_bin2hex>`_) and then used in the configuration file. For
1911 // The string is a hexadecimal representation of a 32-bytes long string of random bytes.
1912 $cfg['blowfish_secret'] = sodium_hex2bin('f16ce59f45714194371b48fe362072dc3b019da7861558cd4ad29e4d6fb13851');
1916 The encryption key must be 32 bytes long. If it is longer than the length of bytes, only the first 32 bytes will
1917 be used, and if it is shorter, a new temporary key will be automatically generated for you. However, this
1918 temporary key will only last for the duration of the session.
1922 The configuration is called blowfish_secret for historical reasons as
1923 Blowfish algorithm was originally used to do the encryption.
1925 .. versionchanged:: 3.1.0
1927 Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
1928 makes a bit weaker security as this generated secret is stored in
1929 session and furthermore it makes impossible to recall user name from
1932 .. versionchanged:: 5.2.0
1934 Since version 5.2.0, phpMyAdmin uses the
1935 `sodium\_crypto\_secretbox <https://www.php.net/sodium_crypto_secretbox>`_ and
1936 `sodium\_crypto\_secretbox\_open <https://www.php.net/sodium_crypto_secretbox_open>`_ PHP functions to encrypt
1937 and decrypt cookies, respectively.
1939 .. seealso:: :ref:`faq2_10`
1941 .. config:option:: $cfg['CookieSameSite']
1944 :default: ``'Strict'``
1946 .. versionadded:: 5.1.0
1948 It sets SameSite attribute of the Set-Cookie :term:`HTTP` response header.
1955 .. seealso:: `rfc6265 bis <https://tools.ietf.org/id/draft-ietf-httpbis-rfc6265bis-03.html#rfc.section.5.3.7>`_
1957 .. config:option:: $cfg['LoginCookieRecall']
1962 Define whether the previous login should be recalled or not in cookie
1963 authentication mode.
1965 This is automatically disabled if you do not have
1966 configured :config:option:`$cfg['blowfish_secret']`.
1968 .. config:option:: $cfg['LoginCookieValidity']
1970 :type: integer [number of seconds]
1973 Define how long a login cookie is valid. Please note that php
1974 configuration option `session.gc\_maxlifetime
1975 <https://www.php.net/manual/en/session.configuration.php#ini.session.gc-
1976 maxlifetime>`_ might limit session validity and if the session is lost,
1977 the login cookie is also invalidated. So it is a good idea to set
1978 ``session.gc_maxlifetime`` at least to the same value of
1979 :config:option:`$cfg['LoginCookieValidity']`.
1981 .. config:option:: $cfg['LoginCookieStore']
1983 :type: integer [number of seconds]
1986 Define how long login cookie should be stored in browser. Default 0
1987 means that it will be kept for existing session. This is recommended
1988 for not trusted environments.
1990 .. config:option:: $cfg['LoginCookieDeleteAll']
1995 If enabled (default), logout deletes cookies for all servers,
1996 otherwise only for current one. Setting this to false makes it easy to
1997 forget to log out from other server, when you are using more of them.
1999 .. _AllowArbitraryServer:
2000 .. config:option:: $cfg['AllowArbitraryServer']
2005 If enabled, allows you to log in to arbitrary servers using cookie
2010 Please use this carefully, as this may allow users access to MySQL servers
2011 behind the firewall where your :term:`HTTP` server is placed.
2012 See also :config:option:`$cfg['ArbitraryServerRegexp']`.
2014 .. config:option:: $cfg['ArbitraryServerRegexp']
2019 Restricts the MySQL servers to which the user can log in when
2020 :config:option:`$cfg['AllowArbitraryServer']` is enabled by
2021 matching the :term:`IP` or the hostname of the MySQL server
2022 to the given regular expression. The regular expression must be enclosed
2023 with a delimiter character.
2025 It is recommended to include start and end symbols in the regular
2026 expression, so that you can avoid partial matches on the string.
2032 // Allow connection to three listed servers:
2033 $cfg['ArbitraryServerRegexp'] = '/^(server|another|yetdifferent)$/';
2035 // Allow connection to range of IP addresses:
2036 $cfg['ArbitraryServerRegexp'] = '@^192\.168\.0\.[0-9]{1,}$@';
2038 // Allow connection to server name ending with -mysql:
2039 $cfg['ArbitraryServerRegexp'] = '@^[^:]\-mysql$@';
2043 The whole server name is matched, it can include port as well. Due to
2044 way MySQL is permissive in connection parameters, it is possible to use
2045 connection strings as ```server:3306-mysql```. This can be used to
2046 bypass regular expression by the suffix, while connecting to another

2184 Defines a string to be used to nest table spaces. This means if you have
2185 tables like ``first__second__third`` this will be shown as a three-level
2186 hierarchy like: first > second > third. If set to false or empty, the
2187 feature is disabled. NOTE: You should not use this separator at the
2188 beginning or end of a table name or multiple times after another without
2189 any other characters in between.
2191 .. config:option:: $cfg['NavigationTreeTableLevel']
2196 Defines how many sublevels should be displayed when splitting up
2197 tables by the above separator.
2199 .. config:option:: $cfg['NumRecentTables']
2204 The maximum number of recently used tables shown in the navigation
2205 panel. Set this to 0 (zero) to disable the listing of recent tables.
2207 .. config:option:: $cfg['NumFavoriteTables']
2212 The maximum number of favorite tables shown in the navigation
2213 panel. Set this to 0 (zero) to disable the listing of favorite tables.

2220 Enables Zero Configuration mode in which the user will be offered a choice to
2221 create phpMyAdmin configuration storage in the current database
2222 or use the existing one, if already present.
2224 This setting has no effect if the phpMyAdmin configuration storage database
2225 is properly created and the related configuration directives (such as

2249 Enter the :term:`URL` where the logo in the navigation panel will point to.
2250 For use especially with self made theme which changes this.
2251 For relative/internal URLs, you need to have leading `` ./ `` or trailing characters `` ? `` such as ``'./index.php?route=/server/sql?'``.
2252 For external URLs, you should include URL protocol schemes (``http`` or ``https``) with absolute URLs.

2259 :default: ``'main'``
2261 Whether to open the linked page in the main window (``main``) or in a
2262 new one (``new``). Note: use ``new`` if you are linking to
2265 To open the link in the main window you will need to add the value of :config:option:`$cfg['NavigationLogoLink']`
2266 to :config:option:`$cfg['CSPAllow']` because of the :term:`Content Security Policy` header.

2284 Defines the minimum number of databases to display a JavaScript filter
2285 box above the list of databases in the navigation tree.
2287 To disable the filter completely some high number can be used
2290 .. config:option:: $cfg['NavigationDisplayServers']
2295 Defines whether or not to display a server choice at the top of the
2298 .. config:option:: $cfg['DisplayServersList']
2303 Defines whether to display this server choice as links instead of in a
2306 .. config:option:: $cfg['NavigationTreeDefaultTabTable']
2309 :default: ``'structure'``
2311 Defines the tab displayed by default when clicking the small icon next
2312 to each table name in the navigation panel. The possible values are the
2313 localized equivalent of:
2321 .. config:option:: $cfg['NavigationTreeDefaultTabTable2']
2326 Defines the tab displayed by default when clicking the second small icon next
2327 to each table name in the navigation panel. The possible values are the
2328 localized equivalent of:
2337 .. config:option:: $cfg['NavigationTreeEnableExpansion']
2342 Whether to offer the possibility of tree expansion in the navigation panel.
2344 .. config:option:: $cfg['NavigationTreeShowTables']
2349 Whether to show tables under database in the navigation panel.
2351 .. config:option:: $cfg['NavigationTreeShowViews']
2356 Whether to show views under database in the navigation panel.
2358 .. config:option:: $cfg['NavigationTreeShowFunctions']
2363 Whether to show functions under database in the navigation panel.

2389 .. config:option:: $cfg['ShowStats']
2394 Defines whether or not to display space usage and statistics about
2395 databases and tables. Note that statistics requires at least MySQL
2396 3.23.3 and that, at this date, MySQL doesn't return such information
2397 for Berkeley DB tables.
2399 .. config:option:: $cfg['ShowServerInfo']
2404 Defines whether to display detailed server information on main page.
2405 You can additionally hide more information by using

2413 Defines whether to display the :guilabel:`PHP information` or not at
2414 the starting main (right) frame.
2416 Please note that to block the usage of ``phpinfo()`` in scripts, you have to
2417 put this in your :file:`php.ini`:
2421 disable_functions = phpinfo()
2425 Enabling phpinfo page will leak quite a lot of information about server
2426 setup. Is it not recommended to enable this on shared installations.
2428 This might also make easier some remote attacks on your installations,
2429 so enable this only when needed.
2431 .. config:option:: $cfg['ShowChgPassword']
2436 Defines whether to display the :guilabel:`Change password` link or not at
2437 the starting main (right) frame. This setting does not check MySQL commands
2440 Please note that enabling the :guilabel:`Change password` link has no effect
2441 with config authentication mode: because of the hard coded password value
2442 in the configuration file, end users can't be allowed to change their
2445 .. config:option:: $cfg['ShowCreateDb']
2450 Defines whether to display the form for creating database or not at the
2451 starting main (right) frame. This setting does not check MySQL commands
2454 .. config:option:: $cfg['ShowGitRevision']
2459 Defines whether to display information about the current Git revision (if
2460 applicable) on the main panel.
2462 .. config:option:: $cfg['MysqlMinVersion']
2466 Defines the minimum supported MySQL version. The default is chosen
2467 by the phpMyAdmin team; however this directive was asked by a developer
2468 of the Plesk control panel to ease integration with older MySQL servers
2469 (where most of the phpMyAdmin features work).
2474 .. config:option:: $cfg['ShowDbStructureCreation']
2479 Defines whether the database structure page (tables list) has a
2480 "Creation" column that displays when each table was created.

2521 Defines whether the table navigation links contain ``'icons'``, ``'text'``
2524 .. config:option:: $cfg['ActionLinksMode']
2527 :default: ``'both'``
2529 If set to ``icons``, will display icons instead of text for db and table
2530 properties links (like :guilabel:`Browse`, :guilabel:`Select`,
2531 :guilabel:`Insert`, ...). Can be set to ``'both'``
2532 if you want icons AND text. When set to ``text``, will only show text.
2534 .. config:option:: $cfg['RowActionType']
2537 :default: ``'both'``
2539 Whether to display icons or text or both icons and text in table row action
2540 segment. Value can be either of ``'icons'``, ``'text'`` or ``'both'``.
2542 .. config:option:: $cfg['ShowAll']
2547 Defines whether a user should be displayed a ":guilabel:`Show all`" button in browse
2548 mode or not in all cases. By default it is shown only on small tables (less
2549 than 500 rows) to avoid performance issues while getting too many rows.
2551 .. config:option:: $cfg['MaxRows']
2556 Number of rows displayed when browsing a result set and no LIMIT
2557 clause is used. If the result set contains more rows, ":guilabel:`Previous`" and
2558 ":guilabel:`Next`" links will be shown. Possible values: 25,50,100,250,500.
2560 .. config:option:: $cfg['Order']
2563 :default: ``'SMART'``
2565 Defines whether columns are displayed in ascending (``ASC``) order, in
2566 descending (``DESC``) order or in a "smart" (``SMART``) order - I.E.
2567 descending order for columns of type TIME, DATE, DATETIME and
2568 TIMESTAMP, ascending order else- by default.
2570 .. versionchanged:: 3.4.0
2571 Since phpMyAdmin 3.4.0 the default value is ``'SMART'``.
2573 .. config:option:: $cfg['GridEditing']
2576 :default: ``'double-click'``
2578 Defines which action (``double-click`` or ``click``) triggers grid
2579 editing. Can be deactivated with the ``disabled`` value.
2581 .. config:option:: $cfg['RelationalDisplay']
2586 Defines the initial behavior for Options > Relational. ``K``, which
2587 is the default, displays the key while ``D`` shows the display column.
2589 .. config:option:: $cfg['SaveCellsAtOnce']
2594 Defines whether or not to save all edited cells at once for grid
2600 .. config:option:: $cfg['ProtectBinary']
2602 :type: boolean or string
2603 :default: ``'blob'``
2605 Defines whether ``BLOB`` or ``BINARY`` columns are protected from
2606 editing when browsing a table's content. Valid values are:
2608 * ``false`` to allow editing of all columns;
2609 * ``'blob'`` to allow editing of all columns except ``BLOBS``;
2610 * ``'noblob'`` to disallow editing of all columns except ``BLOBS`` (the
2611 opposite of ``'blob'``);
2612 * ``'all'`` to disallow editing of all ``BINARY`` or ``BLOB`` columns.
2614 .. config:option:: $cfg['ShowFunctionFields']
2619 Defines whether or not MySQL functions fields should be initially
2620 displayed in edit/insert mode. Since version 2.10, the user can toggle
2621 this setting from the interface.
2623 .. config:option:: $cfg['ShowFieldTypesInDataEditView']
2628 Defines whether or not type fields should be initially displayed in
2629 edit/insert mode. The user can toggle this setting from the interface.
2631 .. config:option:: $cfg['InsertRows']
2636 Defines the default number of rows to be entered from the Insert page.
2637 Users can manually change this from the bottom of that page to add or remove
2640 .. config:option:: $cfg['ForeignKeyMaxLimit']
2645 If there are fewer items than this in the set of foreign keys, then a
2646 drop-down box of foreign keys is presented, in the style described by
2647 the :config:option:`$cfg['ForeignKeyDropdownOrder']` setting.
2649 .. config:option:: $cfg['ForeignKeyDropdownOrder']
2652 :default: array('content-id', 'id-content')
2654 For the foreign key drop-down fields, there are several methods of
2655 display, offering both the key and value data. The contents of the
2656 array should be one or both of the following strings: ``content-id``,
2659 Export and import settings
2660 --------------------------
2662 .. config:option:: $cfg['ZipDump']
2667 .. config:option:: $cfg['GZipDump']
2672 .. config:option:: $cfg['BZipDump']
2677 Defines whether to allow the use of zip/GZip/BZip2 compression when
2678 creating a dump file
2680 .. config:option:: $cfg['CompressOnFly']
2685 Defines whether to allow on the fly compression for GZip/BZip2
2686 compressed exports. This doesn't affect smaller dumps and allows users
2687 to create larger dumps that won't otherwise fit in memory due to php
2688 memory limit. Produced files contain more GZip/BZip2 headers, but all
2689 normal programs handle this correctly.
2691 .. config:option:: $cfg['Export']
2694 :default: array(...)
2696 In this array are defined default parameters for export, names of
2697 items are similar to texts seen on export page, so you can easily
2698 identify what they mean.
2700 .. config:option:: $cfg['Export']['format']
2705 Default export format.
2707 .. config:option:: $cfg['Export']['method']
2710 :default: ``'quick'``
2712 Defines how the export form is displayed when it loads. Valid values
2715 * ``quick`` to display the minimum number of options to configure
2716 * ``custom`` to display every available option to configure
2717 * ``custom-no-form`` same as ``custom`` but does not display the option
2718 of using quick export
2720 .. config:option:: $cfg['Export']['charset']
2725 Defines charset for generated export. By default no charset conversion is
2726 done assuming UTF-8.
2728 .. config:option:: $cfg['Export']['file_template_table']
2731 :default: ``'@TABLE@'``
2733 Default filename template for table exports.
2735 .. seealso:: :ref:`faq6_27`
2737 .. config:option:: $cfg['Export']['file_template_database']
2740 :default: ``'@DATABASE@'``
2742 Default filename template for database exports.

2760 Remove DEFINER clause from the event, view and routine definitions.
2762 .. versionadded:: 5.2.0
2764 .. config:option:: $cfg['Import']
2767 :default: array(...)
2769 In this array are defined default parameters for import, names of
2770 items are similar to texts seen on import page, so you can easily
2771 identify what they mean.
2773 .. config:option:: $cfg['Import']['charset']
2778 Defines charset for import. By default no charset conversion is done
2781 Tabs display settings
2782 ---------------------
2784 .. config:option:: $cfg['TabsMode']
2787 :default: ``'both'``
2789 Defines whether the menu tabs contain ``'icons'``, ``'text'`` or ``'both'``.
2791 .. config:option:: $cfg['PropertiesNumColumns']
2796 How many columns will be utilized to display the tables on the database
2797 property view? When setting this to a value larger than 1, the type of the
2798 database will be omitted for more display space.
2800 .. config:option:: $cfg['DefaultTabServer']
2803 :default: ``'welcome'``
2805 Defines the tab displayed by default on server view. The possible values
2806 are the localized equivalent of:
2808 * ``welcome`` (recommended for multi-user setups)
2814 .. config:option:: $cfg['DefaultTabDatabase']
2817 :default: ``'structure'``
2819 Defines the tab displayed by default on database view. The possible values
2820 are the localized equivalent of:
2827 .. config:option:: $cfg['DefaultTabTable']
2830 :default: ``'browse'``
2832 Defines the tab displayed by default on table view. The possible values
2833 are the localized equivalent of:
2844 .. config:option:: $cfg['PDFPageSizes']
2847 :default: ``array('A3', 'A4', 'A5', 'letter', 'legal')``
2849 Array of possible paper sizes for creating PDF pages.
2851 You should never need to change this.
2853 .. config:option:: $cfg['PDFDefaultPageSize']
2858 Default page size to use when creating PDF pages. Valid values are any
2859 listed in :config:option:`$cfg['PDFPageSizes']`.
2864 .. config:option:: $cfg['DefaultLang']
2869 Defines the default language to use, if not browser-defined or user-
2870 defined. The corresponding language file needs to be in
2871 locale/*code*/LC\_MESSAGES/phpmyadmin.mo.
2873 .. config:option:: $cfg['DefaultConnectionCollation']
2876 :default: ``'utf8mb4_general_ci'``
2878 Defines the default connection collation to use, if not user-defined.
2879 See the `MySQL documentation for charsets
2880 <https://dev.mysql.com/doc/refman/5.7/en/charset-charsets.html>`_
2881 for list of possible values.
2883 .. config:option:: $cfg['Lang']
2888 Force language to use. The corresponding language file needs to be in
2889 locale/*code*/LC\_MESSAGES/phpmyadmin.mo.
2891 .. config:option:: $cfg['FilterLanguages']
2896 Limit list of available languages to those matching the given regular
2897 expression. For example if you want only Czech and English, you should
2898 set filter to ``'^(cs|en)'``.
2900 .. config:option:: $cfg['RecodingEngine']
2903 :default: ``'auto'``
2905 You can select here which functions will be used for character set
2906 conversion. Possible values are:
2908 * auto - automatically use available one (first is tested iconv, then
2910 * iconv - use iconv or libiconv functions
2911 * recode - use recode\_string function
2912 * mb - use :term:`mbstring` extension
2913 * none - disable encoding conversion
2915 Enabled charset conversion activates a pull-down menu in the Export
2916 and Import pages, to choose the character set when exporting a file.
2917 The default value in this menu comes from
2918 :config:option:`$cfg['Export']['charset']` and :config:option:`$cfg['Import']['charset']`.
2920 .. config:option:: $cfg['IconvExtraParams']
2923 :default: ``'//TRANSLIT'``
2925 Specify some parameters for iconv used in charset conversion. See
2926 `iconv documentation <https://www.gnu.org/savannah-checkouts/gnu/libiconv/documentati
2927 on/libiconv-1.15/iconv_open.3.html>`_ for details. By default
2928 ``//TRANSLIT`` is used, so that invalid characters will be
2931 .. config:option:: $cfg['AvailableCharsets']
2934 :default: array(...)
2936 Available character sets for MySQL conversion. You can add your own
2937 (any of supported by recode/iconv) or remove these which you don't
2938 use. Character sets will be shown in same order as here listed, so if
2939 you frequently use some of these move them to the top.
2944 .. config:option:: $cfg['OBGzip']
2946 :type: string/boolean
2947 :default: ``'auto'``
2949 Defines whether to use GZip output buffering for increased speed in
2950 :term:`HTTP` transfers. Set to
2951 true/false for enabling/disabling. When set to 'auto' (string),
2952 phpMyAdmin tries to enable output buffering and will automatically
2953 disable it if your browser has some problems with buffering. IE6 with
2954 a certain patch is known to cause data corruption when having enabled
2957 .. config:option:: $cfg['TrustedProxies']
2962 Lists proxies and HTTP headers which are trusted for
2963 :config:option:`$cfg['Servers'][$i]['AllowDeny']['order']`. This list is by
2964 default empty, you need to fill in some trusted proxy servers if you
2965 want to use rules for IP addresses behind proxy.
2967 The following example specifies that phpMyAdmin should trust a
2968 HTTP\_X\_FORWARDED\_FOR (``X-Forwarded-For``) header coming from the proxy
2973 $cfg['TrustedProxies'] = ['1.2.3.4' => 'HTTP_X_FORWARDED_FOR'];
2975 The :config:option:`$cfg['Servers'][$i]['AllowDeny']['rules']` directive uses the
2976 client's IP address as usual.
2978 .. config:option:: $cfg['GD2Available']
2981 :default: ``'auto'``
2983 Specifies whether GD >= 2 is available. If yes it can be used for MIME
2984 transformations. Possible values are:
2986 * auto - automatically detect
2987 * yes - GD 2 functions can be used
2988 * no - GD 2 function cannot be used
2990 .. config:option:: $cfg['CheckConfigurationPermissions']
2995 We normally check the permissions on the configuration file to ensure
2996 it's not world writable. However, phpMyAdmin could be installed on a
2997 NTFS filesystem mounted on a non-Windows server, in which case the
2998 permissions seems wrong but in fact cannot be detected. In this case a
2999 sysadmin would set this parameter to ``false``.
3001 .. config:option:: $cfg['LinkLengthLimit']
3006 Limit for length of :term:`URL` in links. When length would be above this
3007 limit, it is replaced by form with button. This is required as some web
3008 servers (:term:`IIS`) have problems with long :term:`URL` .
3010 .. config:option:: $cfg['CSPAllow']
3015 Additional string to include in allowed script and image sources in Content
3016 Security Policy header.
3018 This can be useful when you want to include some external JavaScript files
3019 in :file:`config.footer.inc.php` or :file:`config.header.inc.php`, which
3020 would be normally not allowed by :term:`Content Security Policy`.
3022 To allow some sites, just list them within the string:
3026 $cfg['CSPAllow'] = 'example.com example.net';
3028 .. versionadded:: 4.0.4
3030 .. config:option:: $cfg['DisableMultiTableMaintenance']
3035 In the database Structure page, it's possible to mark some tables then
3036 choose an operation like optimizing for many tables. This can slow
3037 down a server; therefore, setting this to ``true`` prevents this kind
3038 of multiple maintenance operation.
3043 Please directly modify :file:`themes/themename/scss/_variables.scss`, although
3044 your changes will be overwritten with the next update.
3046 Design customization
3047 --------------------
3049 .. config:option:: $cfg['NavigationTreePointerEnable']
3054 When set to true, hovering over an item in the navigation panel causes that item to be marked
3055 (the background is highlighted).
3057 .. config:option:: $cfg['BrowsePointerEnable']
3062 When set to true, hovering over a row in the Browse page causes that row to be marked (the background
3065 .. config:option:: $cfg['BrowseMarkerEnable']
3070 When set to true, a data row is marked (the background is highlighted) when the row is selected
3073 .. config:option:: $cfg['LimitChars']
3078 Maximum number of characters shown in any non-numeric field on browse
3079 view. Can be turned off by a toggle button on the browse page.
3081 .. config:option:: $cfg['RowActionLinks']
3084 :default: ``'left'``
3086 Defines the place where table row links (Edit, Copy, Delete) would be
3087 put when tables contents are displayed (you may have them displayed at
3088 the left side, right side, both sides or nowhere).
3090 .. config:option:: $cfg['RowActionLinksWithoutUnique']
3095 Defines whether to show row links (Edit, Copy, Delete) and checkboxes
3096 for multiple row operations even when the selection does not have a :term:`unique key`.
3097 Using row actions in the absence of a unique key may result in different/more
3098 rows being affected since there is no guaranteed way to select the exact row(s).
3100 .. config:option:: $cfg['RememberSorting']
3105 If enabled, remember the sorting of each table when browsing them.
3107 .. config:option:: $cfg['TablePrimaryKeyOrder']
3110 :default: ``'NONE'``
3112 This defines the default sort order for the tables, having a :term:`primary key`,
3113 when there is no sort order defines externally.
3114 Acceptable values : ['NONE', 'ASC', 'DESC']
3116 .. config:option:: $cfg['ShowBrowseComments']
3121 .. config:option:: $cfg['ShowPropertyComments']
3126 By setting the corresponding variable to ``true`` you can enable the
3127 display of column comments in Browse or Property display. In browse
3128 mode, the comments are shown inside the header. In property mode,
3129 comments are displayed using a CSS-formatted dashed-line below the
3130 name of the column. The comment is shown as a tool-tip for that
3133 .. config:option:: $cfg['FirstDayOfCalendar']
3138 This will define the first day of week in the calendar. The number
3139 can be set from 0 to 6, which represents the seven days of the week,
3140 Sunday to Saturday respectively. This value can also be configured by the user
3141 in :guilabel:`Settings` -> :guilabel:`Features` -> :guilabel:`General` -> :guilabel:`First day of calendar` field.
3146 .. config:option:: $cfg['CharEditing']
3149 :default: ``'input'``
3151 Defines which type of editing controls should be used for CHAR and
3152 VARCHAR columns. Applies to data editing and also to the default values
3153 in structure editing. Possible values are:
3155 * input - this allows to limit size of text to size of columns in MySQL,
3156 but has problems with newlines in columns
3157 * textarea - no problems with newlines in columns, but also no length
3160 .. config:option:: $cfg['MinSizeForInputField']
3165 Defines the minimum size for input fields generated for CHAR and
3168 .. config:option:: $cfg['MaxSizeForInputField']
3173 Defines the maximum size for input fields generated for CHAR and
3176 .. config:option:: $cfg['TextareaCols']
3181 .. config:option:: $cfg['TextareaRows']
3186 .. config:option:: $cfg['CharTextareaCols']
3191 .. config:option:: $cfg['CharTextareaRows']
3196 Number of columns and rows for the textareas. This value will be
3197 emphasized (\*2) for :term:`SQL` query
3198 textareas and (\*1.25) for :term:`SQL`
3199 textareas inside the query window.
3201 The Char\* values are used for CHAR
3202 and VARCHAR editing (if configured via :config:option:`$cfg['CharEditing']`).
3204 .. versionchanged:: 5.0.0
3206 The default value was changed from 2 to 7.
3208 .. config:option:: $cfg['LongtextDoubleTextarea']
3213 Defines whether textarea for LONGTEXT columns should have double size.
3215 .. config:option:: $cfg['TextareaAutoSelect']
3220 Defines if the whole textarea of the query box will be selected on
3223 .. config:option:: $cfg['EnableAutocompleteForTablesAndColumns']
3228 Whether to enable autocomplete for table and column names in any
3231 SQL query box settings
3232 ----------------------
3234 .. config:option:: $cfg['SQLQuery']['Edit']
3239 Whether to display an edit link to change a query in any SQL Query
3242 .. config:option:: $cfg['SQLQuery']['Explain']
3247 Whether to display a link to explain a SELECT query in any SQL Query
3250 .. config:option:: $cfg['SQLQuery']['ShowAsPHP']
3255 Whether to display a link to wrap a query in PHP code in any SQL Query
3258 .. config:option:: $cfg['SQLQuery']['Refresh']
3263 Whether to display a link to refresh a query in any SQL Query box.
3267 Web server upload/save/import directories
3268 -----------------------------------------
3270 If PHP is running in safe mode, all directories must be owned by the same user
3271 as the owner of the phpMyAdmin scripts.
3273 If the directory where phpMyAdmin is installed is subject to an
3274 ``open_basedir`` restriction, you need to create a temporary directory in some
3275 directory accessible by the PHP interpreter.
3277 For security reasons, all directories should be outside the tree published by
3278 webserver. If you cannot avoid having this directory published by webserver,
3279 limit access to it either by web server configuration (for example using
3280 .htaccess or web.config files) or place at least an empty :file:`index.html`
3281 file there, so that directory listing is not possible. However as long as the
3282 directory is accessible by web server, an attacker can guess filenames to download
3285 .. config:option:: $cfg['UploadDir']
3290 The name of the directory where :term:`SQL` files have been uploaded by
3291 other means than phpMyAdmin (for example, FTP). Those files are available
3292 under a drop-down box when you click the database or table name, then the
3296 you want different directory for each user, %u will be replaced with
3299 Please note that the file names must have the suffix ".sql"
3300 (or ".sql.bz2" or ".sql.gz" if support for compressed formats is
3303 This feature is useful when your file is too big to be
3304 uploaded via :term:`HTTP`, or when file
3305 uploads are disabled in PHP.
3309 Please see top of this chapter (:ref:`web-dirs`) for instructions how
3310 to setup this directory and how to make its usage secure.
3314 See :ref:`faq1_16` for alternatives.
3316 .. config:option:: $cfg['SaveDir']
3321 The name of the webserver directory where exported files can be saved.
3323 If you want a different directory for each user, %u will be replaced with the
3326 Please note that the directory must exist and has to be writable for
3327 the user running webserver.
3331 Please see top of this chapter (:ref:`web-dirs`) for instructions how
3332 to setup this directory and how to make its usage secure.
3334 .. config:option:: $cfg['TempDir']
3337 :default: ``'./tmp/'``
3339 The name of the directory where temporary files can be stored. It is used
3340 for several purposes, currently:
3342 * The templates cache which speeds up page loading.
3343 * ESRI Shapefiles import, see :ref:`faq6_30`.
3344 * To work around limitations of ``open_basedir`` for uploaded files, see
3347 This directory should have as strict permissions as possible as the only
3348 user required to access this directory is the one who runs the webserver.
3349 If you have root privileges, simply make this user owner of this directory
3350 and make it accessible only by it:
3354 chown www-data:www-data tmp
3357 If you cannot change owner of the directory, you can achieve a similar
3358 setup using :term:`ACL`:
3363 setfacl -m "g:www-data:rwx" tmp
3364 setfacl -d -m "g:www-data:rwx" tmp
3366 If neither of above works for you, you can still make the directory
3367 :command:`chmod 777`, but it might impose risk of other users on system
3368 reading and writing data in this directory.
3372 Please see top of this chapter (:ref:`web-dirs`) for instructions how
3373 to setup this directory and how to make its usage secure.
3375 Various display setting
3376 -----------------------
3378 .. config:option:: $cfg['RepeatCells']
3383 Repeat the headers every X cells, or 0 to deactivate.
3385 .. config:option:: $cfg['QueryHistoryDB']
3390 .. config:option:: $cfg['QueryHistoryMax']
3395 If :config:option:`$cfg['QueryHistoryDB']` is set to ``true``, all your
3396 Queries are logged to a table, which has to be created by you (see
3397 :config:option:`$cfg['Servers'][$i]['history']`). If set to false, all your
3398 queries will be appended to the form, but only as long as your window is
3399 opened they remain saved.
3401 When using the JavaScript based query window, it will always get updated
3402 when you click on a new table/db to browse and will focus if you click on
3403 :guilabel:`Edit SQL` after using a query. You can suppress updating the
3404 query window by checking the box :guilabel:`Do not overwrite this query
3405 from outside the window` below the query textarea. Then you can browse
3406 tables/databases in the background without losing the contents of the
3407 textarea, so this is especially useful when composing a query with tables
3408 you first have to look in. The checkbox will get automatically checked
3409 whenever you change the contents of the textarea. Please uncheck the button
3410 whenever you definitely want the query window to get updated even though
3411 you have made alterations.
3413 If :config:option:`$cfg['QueryHistoryDB']` is set to ``true`` you can
3414 specify the amount of saved history items using
3415 :config:option:`$cfg['QueryHistoryMax']`.
3417 .. config:option:: $cfg['BrowseMIME']
3422 Enable :ref:`transformations`.
3424 .. config:option:: $cfg['MaxExactCount']
3429 For InnoDB tables, determines for how large tables phpMyAdmin should
3430 get the exact row count using ``SELECT COUNT``. If the approximate row
3431 count as returned by ``SHOW TABLE STATUS`` is smaller than this value,
3432 ``SELECT COUNT`` will be used, otherwise the approximate count will be
3435 .. versionchanged:: 4.8.0
3437 The default value was lowered to 50000 for performance reasons.
3439 .. versionchanged:: 4.2.6
3441 The default value was changed to 500000.
3443 .. seealso:: :ref:`faq3_11`
3445 .. config:option:: $cfg['MaxExactCountViews']
3450 For VIEWs, since obtaining the exact count could have an impact on
3451 performance, this value is the maximum to be displayed, using a
3452 ``SELECT COUNT ... LIMIT``. Setting this to 0 bypasses any row
3455 .. config:option:: $cfg['NaturalOrder']
3460 Sorts database and table names according to natural order (for
3461 example, t1, t2, t10). Currently implemented in the navigation panel
3462 and in Database view, for the table list.
3464 .. config:option:: $cfg['InitialSlidersState']
3467 :default: ``'closed'``
3469 If set to ``'closed'``, the visual sliders are initially in a closed
3470 state. A value of ``'open'`` does the reverse. To completely disable
3471 all visual sliders, use ``'disabled'``.
3473 .. config:option:: $cfg['UserprefsDisallow']
3478 Contains names of configuration options (keys in ``$cfg`` array) that
3479 users can't set through user preferences. For possible values, refer
3480 to classes under :file:`libraries/classes/Config/Forms/User/`.
3482 .. config:option:: $cfg['UserprefsDeveloperTab']
3487 .. versionadded:: 3.4.0
3489 Activates in the user preferences a tab containing options for
3490 developers of phpMyAdmin.
3495 .. config:option:: $cfg['TitleTable']
3498 :default: ``'@HTTP_HOST@ / @VSERVER@ / @DATABASE@ / @TABLE@ | @PHPMYADMIN@'``
3500 .. config:option:: $cfg['TitleDatabase']
3503 :default: ``'@HTTP_HOST@ / @VSERVER@ / @DATABASE@ | @PHPMYADMIN@'``
3505 .. config:option:: $cfg['TitleServer']
3508 :default: ``'@HTTP_HOST@ / @VSERVER@ | @PHPMYADMIN@'``
3510 .. config:option:: $cfg['TitleDefault']
3513 :default: ``'@HTTP_HOST@ | @PHPMYADMIN@'``
3515 Allows you to specify window's title bar. You can use :ref:`faq6_27`.
3517 Theme manager settings
3518 ----------------------
3520 .. config:option:: $cfg['ThemeManager']
3525 Enables user-selectable themes. See :ref:`faqthemes`.
3527 .. config:option:: $cfg['ThemeDefault']
3530 :default: ``'pmahomme'``
3532 The default theme (a subdirectory under :file:`./themes/`).
3534 .. config:option:: $cfg['ThemePerServer']
3539 Whether to allow different theme for each server.
3541 .. config:option:: $cfg['FontSize']
3546 .. deprecated:: 5.0.0
3548 This setting was removed as the browser is more efficient,
3549 thus no need of this option.
3551 Font size to use, is applied in CSS.
3556 .. config:option:: $cfg['DefaultQueryTable']
3559 :default: ``'SELECT * FROM @TABLE@ WHERE 1'``
3561 .. config:option:: $cfg['DefaultQueryDatabase']
3566 Default queries that will be displayed in query boxes when user didn't
3567 specify any. You can use standard :ref:`faq6_27`.
3572 .. config:option:: $cfg['DefaultFunctions']
3575 :default: ``array('FUNC_CHAR' => '', 'FUNC_DATE' => '', 'FUNC_NUMBER' => '', 'FUNC_SPATIAL' => 'GeomFromText', 'FUNC_UUID' => 'UUID', 'first_timestamp' => 'NOW')``
3577 Functions selected by default when inserting/changing row, Functions
3578 are defined for meta types as (``FUNC_NUMBER``, ``FUNC_DATE``, ``FUNC_CHAR``,
3579 ``FUNC_SPATIAL``, ``FUNC_UUID``) and for ``first_timestamp``, which is used
3580 for first timestamp column in table.
3582 Example configuration
3586 $cfg['DefaultFunctions'] = [
3589 'FUNC_NUMBER' => '',
3590 'FUNC_SPATIAL' => 'ST_GeomFromText',

3688 Switch to dark theme
3690 .. config:option:: $cfg['Console']['Mode']
3697 .. config:option:: $cfg['Console']['Height']
3709 These settings might have huge effect on performance or security.
3711 .. config:option:: $cfg['environment']
3714 :default: ``'production'``
3716 Sets the working environment.
3718 This only needs to be changed when you are developing phpMyAdmin itself.
3719 The ``development`` mode may display debug information in some places.
3721 Possible values are ``'production'`` or ``'development'``.
3723 .. config:option:: $cfg['DBG']
3728 .. config:option:: $cfg['DBG']['sql']
3733 Enable logging queries and execution times to be
3734 displayed in the console's Debug SQL tab.
3736 .. config:option:: $cfg['DBG']['sqllog']
3741 Enable logging of queries and execution times to the syslog.
3742 Requires :config:option:`$cfg['DBG']['sql']` to be enabled.
3744 .. config:option:: $cfg['DBG']['demo']
3749 Enable to let server present itself as demo server.
3750 This is used for `phpMyAdmin demo server <https://www.phpmyadmin.net/try/>`_.
3752 It currently changes following behavior:
3754 * There is welcome message on the main page.
3755 * There is footer information about demo server and used Git revision.
3756 * The setup script is enabled even with existing configuration.
3757 * The setup does not try to connect to the MySQL server.
3759 .. config:option:: $cfg['DBG']['simple2fa']
3764 Can be used for testing two-factor authentication using :ref:`simple2fa`.
3766 .. _config-examples:
3771 See following configuration snippets for typical setups of phpMyAdmin.
3776 Example configuration file, which can be copied to :file:`config.inc.php` to
3777 get some core configuration layout; it is distributed with phpMyAdmin as
3778 :file:`config.sample.inc.php`. Please note that it does not contain all
3779 configuration options, only the most frequently used ones.
3781 .. literalinclude:: ../config.sample.inc.php
3786 Don't use the controluser 'pma' if it does not yet exist and don't use 'pmapass'
3791 Example for signon authentication
3792 +++++++++++++++++++++++++++++++++
3794 This example uses :file:`examples/signon.php` to demonstrate usage of :ref:`auth_signon`:
3801 $cfg['Servers'][$i]['auth_type'] = 'signon';
3802 $cfg['Servers'][$i]['SignonSession'] = 'SignonSession';
3803 $cfg['Servers'][$i]['SignonURL'] = 'examples/signon.php';
3805 Example for IP address limited autologin
3806 ++++++++++++++++++++++++++++++++++++++++
3808 If you want to automatically login when accessing phpMyAdmin locally while asking
3809 for a password when accessing remotely, you can achieve it using following snippet:
3813 if ($_SERVER['REMOTE_ADDR'] === '127.0.0.1') {
3814 $cfg['Servers'][$i]['auth_type'] = 'config';
3815 $cfg['Servers'][$i]['user'] = 'root';
3816 $cfg['Servers'][$i]['password'] = 'yourpassword';
3818 $cfg['Servers'][$i]['auth_type'] = 'cookie';
3823 Filtering based on IP addresses isn't reliable over the internet, use it
3824 only for local address.
3826 Example for using multiple MySQL servers
3827 ++++++++++++++++++++++++++++++++++++++++
3829 You can configure any number of servers using :config:option:`$cfg['Servers']`,
3830 following example shows two of them:
3835 // The string is a hexadecimal representation of a 32-bytes long string of random bytes.
3836 $cfg['blowfish_secret'] = sodium_hex2bin('f16ce59f45714194371b48fe362072dc3b019da7861558cd4ad29e4d6fb13851');
3840 $cfg['Servers'][$i]['auth_type'] = 'cookie';
3841 $cfg['Servers'][$i]['verbose'] = 'no1';
3842 $cfg['Servers'][$i]['host'] = 'localhost';
3843 // more options for #1 ...
3846 $cfg['Servers'][$i]['auth_type'] = 'cookie';
3847 $cfg['Servers'][$i]['verbose'] = 'no2';
3848 $cfg['Servers'][$i]['host'] = 'remote.host.addr';//or ip:'10.9.8.1'
3849 // this server must allow remote clients, e.g., host 10.9.8.%
3850 // not only in mysql.host but also in the startup configuration
3851 // more options for #2 ...
3853 // end of server sections

3860 Google Cloud SQL with SSL
3861 +++++++++++++++++++++++++
3863 To connect to Google Could SQL, you currently need to disable certificate
3864 verification. This is caused by the certificate being issued for CN matching
3865 your instance name, but you connect to an IP address and PHP tries to match
3866 these two. With verification you end up with error message like:
3868 .. code-block:: text
3870 Peer certificate CN=`api-project-851612429544:pmatest' did not match expected CN=`8.8.8.8'
3874 With disabled verification your traffic is encrypted, but you're open to
3875 man in the middle attacks.
3877 To connect phpMyAdmin to Google Cloud SQL using SSL download the client and
3878 server certificates and tell phpMyAdmin to use them:
3882 // IP address of your instance
3883 $cfg['Servers'][$i]['host'] = '8.8.8.8';
3884 // Use SSL for connection
3885 $cfg['Servers'][$i]['ssl'] = true;
