95 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
96 a single database. To accomplish the latter you'll need a properly set up
97 MySQL user who can read/write only the desired database. It's up to you to
98 look up the appropriate part in the MySQL manual.
101 <h3>Currently phpMyAdmin can:
</h3>
103 <ul><li>browse and drop databases, tables, views, fields and indexes

143 <h4>A word about users:
</h4>
144 <p> Many people have difficulty
145 understanding the concept of user management with regards to phpMyAdmin. When
146 a user logs in to phpMyAdmin, that username and password are passed directly
147 to MySQL. phpMyAdmin does no account management on its own (other than
148 allowing one to manipulate the MySQL user account information); all users
149 must be valid MySQL users.
</p>
151 <p class=
"footnote" id=
"footnote_1">
152 <sup>1)
</sup> phpMyAdmin can compress (Zip, GZip -RFC
1952- or Bzip2 formats)
153 dumps and
<abbr title=

</abbr> exports if you use
154 PHP with Zlib support (
<tt>--with-zlib
</tt>) and/or Bzip2 support
155 (
<tt>--with-bz2

169 phpMyAdmin does not apply any special security methods to the MySQL database
170 server. It is still the system administrator's job to grant permissions on
171 the MySQL databases properly. phpMyAdmin's

</h3>
187 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
188 Downloads page. Some kits contain only the English messages,
189 others contain all languages in UTF-
8 format (this should be fine
190 in most situations), others contain all
191 languages and all character sets. We'll assume you chose a kit whose
192 name looks like
<tt>phpMyAdmin-x.x.x-all-languages.tar.gz
</tt>.
194 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
195 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz
</tt> in your webserver's
196 document root. If you don't have direct access to your document root,
197 put the files in a directory on your local machine, and, after step
4,
198 transfer the directory on your web server using, for example, ftp.
</li>
199 <li>Ensure that all the scripts have the appropriate owner (if PHP is
200 running in safe mode, having some scripts with an owner different
201 from the owner of other scripts will be a
202 problem). See
<a href=
"#faq4_2">
203 <abbr title=
"Frequently Asked Questions">FAQ
</abbr> 4.2</a> and
204 <a href=
"#faq1_26"><abbr title=
"Frequently Asked Questions">FAQ
</abbr>
205 1.26</a> for suggestions.
</li>
206 <li>Now you must configure your installation. There are two methods that
207 can be used. Traditionally, users have hand-edited a copy of
208 <tt>config.inc.php
</tt>, but now a wizard-style setup script is
209 provided for those who prefer a graphical installation. Creating a
210 <tt>config.inc.php
</tt> is still a quick way to get started and needed for some advanced features.
211 <ul><li>To manually create the file, simply use your text editor to
212 create the file
<tt>config.inc.php
</tt> (you can copy
213 <tt>config.sample.inc.php
</tt> to get minimal configuration
214 file) in the main (top-level) phpMyAdmin directory (the one
215 that contains
<tt>index.php
</tt>). phpMyAdmin first loads
216 <tt>libraries/config.default.php
</tt> and then overrides those
217 values with anything found in
<tt>config.inc.php
</tt>. If the
218 default value is okay for a particular setting, there is no
219 need to include it in
<tt>config.inc.php
</tt>. You'll need a
220 few directives to get going, a simple configuration may look
224 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
228 $cfg['Servers'][$i]['auth_type'] = 'cookie';
231 Or, if you prefer to not be prompted every time you log in:
237 $cfg['Servers'][$i]['user'] = 'root';
238 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
241 For a full explanation of possible configuration values, see the
242 <a href=
"#config">Configuration Section
</a> of this document.
</li>
243 <li id=
"setup_script">Instead of manually editing
244 <tt>config.inc.php
</tt>, you can use the
245 <a href=
"setup/">Setup Script
</a>. First you must
246 manually create a folder
<tt>config
</tt> in the phpMyAdmin
247 directory. This is a security measure. On a Linux/Unix system you
248 can use the following commands:
251 mkdir config # create directory for saving
252 chmod o+rw config # give it world writable permissions
254 And to edit an existing configuration, copy it over first:
256 cp config.inc.php config/ # copy current configuration for editing
257 chmod o+w config/config.inc.php # give it world writable permissions
259 On other platforms, simply create the folder and ensure that your
260 web server has read and write access to it.
<a href=
"#faq1_26">FAQ
261 1.26</a> can help with this.
<br /><br />
263 Next, open
<tt><a href=
"setup/">setup/
</a>
264 </tt>in your browser. Note that
<strong>changes are not saved to
265 disk until explicitly choose
<tt>Save
</tt></strong> from the
266 <i>Configuration
</i> area of the screen. Normally the script saves
267 the new config.inc.php to the
<tt>config/
</tt> directory, but if
268 the webserver does not have the proper permissions you may see the
269 error
"Cannot load or save configuration." Ensure that the
<tt>
270 config/
</tt> directory exists and has the proper permissions -
271 or use the
<tt>Download
</tt> link to save the config file locally
272 and upload (via FTP or some similar means) to the proper location.
<br /><br />
274 Once the file has been saved, it must be moved out of the
<tt>
275 config/
</tt> directory and the permissions must be reset, again
276 as a security measure:
278 mv config/config.inc.php . # move file to current directory
279 chmod o-rw config.inc.php # remove world read and write permissions
281 Now the file is ready to be used. You can choose to review or edit
282 the file with your favorite editor, if you prefer to set some
283 advanced options which the setup script does not provide.
</li></ul></li>
284 <li>If you are using the
285 <tt>auth_type
</tt> "config
", it is suggested that you
286 protect the phpMyAdmin installation directory because using
287 config does not require a user to
288 enter a password to access the phpMyAdmin installation. Use of an alternate
289 authentication method is recommended, for example with
290 HTTP
–AUTH in a
<a href=
"#glossary"><i>.htaccess
</i></a> file or switch to using
291 <tt>auth_type
</tt> cookie or http. See the
292 <a href=
"#faqmultiuser"> multi
–user sub
–section
</a> of this
293 <abbr title=
"Frequently Asked Questions">FAQ
</abbr> for additional
294 information, especially
<a href=
"#faq4_4">
295 <abbr title=
"Frequently Asked Questions">FAQ
</abbr> 4.4</a>.
</li>
296 <li>Open the
<a href=
"index.php">main phpMyAdmin directory
</a>
297 in your browser. phpMyAdmin should now display a welcome screen
298 and your databases, or a login dialog if using
299 <abbr title=
"HyperText Transfer Protocol">HTTP
</abbr> or cookie
300 authentication mode.
</li>
301 <li>You should deny access to the
<tt>./libraries
</tt> and
302 <tt>./setup/lib
</tt> subfolders in your webserver configuration. For
303 Apache you can use supplied .htaccess file in that folder, for other
304 webservers, you should configure this yourself. Such configuration
305 prevents from possible path exposure and cross side scripting
306 vulnerabilities that might happen to be found in that code.
</li>
308 It is generally good idea to protect public phpMyAdmin installation
309 against access by robots as they usually can not do anything good
310 there. You can do this using
<code>robots.txt
</code> file in root of
311 your webserver or limit access by web server configuration. You can
312 find example
<code>.htaccess
</code> file which can help you achieve
313 this in
<code>contrib
</code> directory in phpMyAdmin.
317 <h3 id=
"linked-tables">Linked-tables infrastructure
</h3>
319 <p> For a whole set of new features (bookmarks, comments,
320 <abbr title=
"structured query language">SQL
</abbr>-history,
321 <abbr title=
"Portable Document Format">PDF
</abbr>-generation, field contents
322 transformation, etc.) you need to create a set of special tables. Those
323 tables can be located in your own database, or in a central database for a
324 multi-user installation (this database would then be accessed by the
325 controluser, so no other user should have rights to it).
</p>
327 <p> Please look at your
<tt>./scripts/
</tt> directory, where you should find a
328 file called
<i>create_tables.sql
</i>. (If you are using a Windows server, pay
329 special attention to
<a href=
"#faq1_23">
330 <abbr title=
"Frequently Asked Questions">FAQ
</abbr> 1.23</a>).
</p>
332 <p> If you already had this infrastructure and upgraded to MySQL
4.1.2
333 or newer, please use
<i>./scripts/upgrade_tables_mysql_4_1_2+.sql
</i>.
</p>
335 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
336 that you may need special (administrator) privileges to create the database
337 and tables, and that the script may need some tuning, depending on the
340 <p> After having imported the
<i>./scripts/create_tables.sql
</i> file, you
341 should specify the table names in your
<i>./config.inc.php
</i> file. The
342 directives used for that can be found in the
<a href=
"#config">Configuration
343 section
</a>. You will also need to have a controluser with the proper rights
344 to those tables (see section
<a href=
"#authentication_modes">Using
345 authentication modes
</a> below).
</p>
347 <h3 id=
"upgrading">Upgrading from an older version
</h3>
349 <p> Simply copy
<i>./config.inc.php
</i> from your previous installation into the newly
350 unpacked one. Configuration files from very old versions (
2.3.0 or before) may
351 require some tweaking as some options have been changed or removed.
352 For compatibility with PHP
6, remove a
<tt>set_magic_quotes_runtime(
0);
</tt>
353 statement that you might find near the end of your configuration file.
</p>
355 <p> You should
<strong>not
</strong> copy
<tt>libraries/config.default.php
</tt>
356 over
<tt>config.inc.php
</tt> because the default configuration file
357 is version-specific.
</p>
359 <p> If you have upgraded your MySQL server from a version previous to
4.1.2 to
360 version
4.1.2 or newer and if you use the pmadb/linked table infrastructure,
361 you should run the SQL script found in
362 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql
</tt>.
</p>
364 <h3 id=
"authentication_modes">Using authentication modes
</h3>
366 <ul><li><abbr title=
"HyperText Transfer Protocol">HTTP
</abbr> and cookie
367 authentication modes are recommended in a
<b>multi-user environment
</b>
368 where you want to give users access to their own database and don't want
369 them to play around with others.
<br />
370 Nevertheless be aware that MS Internet Explorer seems to be really buggy
371 about cookies, at least till version
6, and PHP
4.1.1 is also a bit buggy
373 Even in a
<b>single-user environment
</b>, you might prefer to use
374 <abbr title=
"HyperText Transfer Protocol">HTTP
</abbr> or cookie mode so
375 that your user/password pair are not in clear in the configuration file.
378 <li><abbr title=
"HyperText Transfer Protocol">HTTP
</abbr> and cookie
379 authentication modes are more secure: the MySQL login information does
380 not need to be set in the phpMyAdmin configuration file (except possibly
381 for the
<a href=
"#controluser">controluser
</a>).
<br />
382 However, keep in mind that the password travels in plain text, unless
383 you are using the HTTPS protocol.
<br />
384 In cookie mode, the password is stored, encrypted with the blowfish
385 algorithm, in a temporary cookie.
</li>
387 <li>Note: starting with phpMyAdmin
2.6.1, this section is only applicable if
388 your MySQL server is running with
<tt>--skip-show-database
</tt>.
<br /><br />
390 For '
<abbr title=
"HyperText Transfer Protocol">HTTP
</abbr>' and 'cookie'
391 modes, phpMyAdmin needs a controluser that has
<b>only
</b> the
392 <tt>SELECT
</tt> privilege on the
<i>`mysql`.`user` (all columns except
393 `Password`)
</i>,
<i>`mysql`.`db` (all columns)
</i>,
<i>`mysql`.`host`
394 (all columns)
</i> and
<i>`mysql`.`tables_priv` (all columns except
395 `Grantor` and `Timestamp`)
</i> tables.
<br /> You must specify the details
396 for the
<a href=
"#controluser">controluser
</a> in the
<tt>config.inc.php
</tt>
398 <tt><a href=
"#cfg_Servers_controluser" class=
"configrule">
399 $cfg['Servers'][$i]['controluser']
</a></tt> and
400 <tt><a href=
"#cfg_Servers_controlpass" class=
"configrule">
401 $cfg['Servers'][$i]['controlpass']
</a></tt> settings.
<br />
402 The following example assumes you want to use
<tt>pma
</tt> as the
403 controluser and
<tt>pmapass
</tt> as the controlpass, but
<b>this is
404 only an example: use something else in your file!
</b> Input these
405 statements from the phpMyAdmin SQL Query window or mysql command
–line
407 Of course you have to replace
<tt>localhost
</tt> with the webserver's host
408 if it's not the same as the MySQL server's one.
411 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
413 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
414 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
415 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
416 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
417 Execute_priv, Repl_slave_priv, Repl_client_priv
418 ) ON mysql.user TO 'pma'@'localhost';
419 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
420 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
421 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
422 ON mysql.tables_priv TO 'pma'@'localhost';
</pre>
424 If you want to use the many new relation and bookmark features:
427 GRANT SELECT, INSERT, UPDATE, DELETE ON
<pma_db
>.* TO 'pma'@'localhost';
430 (this of course requires that your
<a href=
"#linked-tables">linked-tables
431 infrastructure
</a> be set up).
<br /></li>
433 <li>Then each of the
<i>true
</i> users should be granted a set of privileges
434 on a set of particular databases. Normally you shouldn't give global
435 privileges to an ordinary user, unless you understand the impact of those
436 privileges (for example, you are creating a superuser).
<br />
437 For example, to grant the user
<i>real_user
</i> with all privileges on
438 the database
<i>user_base
</i>:
<br />
441 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
444 What the user may now do is controlled entirely by the MySQL user
445 management system.
<br />
446 With
<abbr title=
"HyperText Transfer Protocol">HTTP

447 authentication mode, you don't need to fill the user/password fields

478 <li>Obviously, the user must enable cookies in the browser, but this is

501 <ul><li>This mode is the less secure one because it requires you to fill the

</a> and
504 <a href=
"#servers_user" class=
"configrule">
505 $cfg['Servers'][$i]['password']
</a> fields (and as a result, anyone who
506 can read your config.inc.php can discover your username and password).
508 But you don't need to setup a
"controluser

522 <li>Unlike cookie and http, does not require a user to log in when first
523 loading the phpMyAdmin site. This is by design but could allow any
524 user to access your installation. Use of some restriction method is
525 suggested, perhaps a
<a href=
"#glossary">.htaccess
</a> file with the
526 HTTP-AUTH directive or disallowing incoming HTTP requests at
527 one
’s router or firewall will suffice (both of which
528 are beyond the scope of this manual but easily searchable with Google).

530 <h4 id=
"swekey">Swekey authentication
</h4>
532 The Swekey is a low cost authentication USB key that can be used in
533 web applications.
<br /><br />
534 When Swekey authentication is activated, phpMyAdmin requires the
535 users's Swekey to be plugged before entering the login page (currently
536 supported for cookie authentication mode only). Swekey Authentication is
537 disabled by default.
<br /><br />
538 To enable it, add the following line to
<tt>config.inc.php
</tt>:
541 $cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';
544 You then have to create the
<tt>swekey.conf
</tt> file that will associate
545 each user with their Swekey Id. It is important to place this file outside
546 of your web server's document root (in the example, it is located in
<tt>/etc
</tt>). A self documented sample file is provided
547 in the
<tt>contrib
</tt> directory. Feel free to use it with your own
548 users' information.

549 If you want to purchase a Swekey please visit

939 the relations between your tables. To do this it needs two tables
940 "pdf_pages

964 Since release
2.3.0 you can store comments to describe each column for

968 Starting with release
2.5.0, comments are consequently used on the table
969 property pages and table browse view, showing up as tool-tips above the
970 column name (properties page) or embedded within the header of table in
971 browse view. They can also be shown in a table dump. Please see the
972 relevant configuration directives later on.
<br /><br />
974 Also new in release
2.5.0 is a MIME-transformation system which is also
975 based on the following table structure. See
<a href=
"#transformations">
976 Transformations
</a> for further information. To use the
977 MIME-transformation system, your column_info table has to have the three
978 new fields 'mimetype', 'transformation', 'transformation_options'.

1075 If your rule order is set to

</tt> then the system applies
1076 all deny rules followed by allow rules. Access is allowed by default. Any

1078 will be allowed access to the server.
<br /><br />
1080 If your rule order is set to

1735 the rotation of the header for horizontalflipped is done via CSS. If
1736 set to 'fake' PHP does the transformation for you, but of course this
1737 does not look as good as CSS.

1744 'vertical' you can have each field lined up vertically beneath each
1745 other. You can save up a lot of place on the horizontal direction and
1746 no longer have to scroll. If you set this to integer, editing of fewer
1747 columns will appear in 'vertical' mode, while editing of more fields
1748 still in 'horizontal' mode. This way you can still effectively edit

1833 If the directory where phpMyAdmin is installed is subject to an
1834 <tt>open_basedir
</tt> restriction, you need to create a
1835 temporary directory in some directory accessible by the web
1836 server. However for security reasons, this directory should be outside
1837 the tree published by webserver. If you cannot avoid having this
1838 directory published by webserver, place at least an empty
1839 <tt>index.html
</tt> file there, so that directory listing is not
1843 This directory should have as strict permissions as possible as the only
1844 user required to access this directory is the one who runs the
1845 webserver. If you have root privileges, simply make this user owner of
1846 this directory and make it accessible only by it:
1850 chown www-data:www-data tmp
1854 If you cannot change owner of the directory, you can achieve a similar
1855 setup using
<abbr title=
"Access Control List">ACL
</abbr>:
1859 setfacl -m
"g:www-data:rwx" tmp
1860 setfacl -d -m
"g:www-data:rwx" tmp
1863 If neither of above works for you, you can still make the directory

1895 All those variables affect the query window feature. A
<tt><abbr title=
"structured query language">SQL
</abbr></tt> link
1896 or icon is always displayed on the left panel. If JavaScript is enabled in
1897 your browser, a click on this opens a distinct query window, which is
1898 a direct interface to enter
<abbr title=
"structured query language">SQL
</abbr> queries. Otherwise, the right panel
1899 changes to display a query box.
<br /><br />
1901 The size of this query window can be customized with
1902 <tt>$cfg['QueryWindowWidth']
</tt> and
<tt>$cfg['QueryWindowWidth']
</tt>
1903 - both integers for the size in pixels. Note that normally, those
1904 parameters will be modified in
<tt>layout.inc.php
</tt> for the
1905 theme you are using.
<br /><br />
1907 If
<tt>$cfg['EditInWindow']
</tt> is set to true, a click on [Edit]
1908 from the results page (in the
"Showing Rows
" section)
1909 opens the query window and puts the current query
1910 inside it. If set to false, clicking on the link puts the
<abbr title=
"structured query language">SQL
</abbr>
1911 query in the right panel's query box.
1913 The usage of the JavaScript query window is recommended if you have a
1914 JavaScript enabled browser. Basic functions are used to exchange quite
1915 a few variables, so most
4th generation browsers should be capable to
1916 use that feature. It currently is only tested with Internet Explorer
6
1919 If
<tt>$cfg['QueryHistoryDB']
</tt> is set to
<tt>TRUE
</tt>, all your Queries are logged
1920 to a table, which has to be created by you (see
<a
1921 href=
"#history" class=
"configrule">$cfg['Servers'][$i]['history']
</a>). If set to FALSE,
1922 all your queries will be appended to the form, but only as long as
1923 your window is opened they remain saved.
1925 When using the JavaScript based query window, it will always get
1926 updated when you click on a new table/db to browse and will focus if
1927 you click on
"Edit <abbr title="structured query language
">SQL</abbr>" after using a query. You can suppress updating
1928 the query window by checking the box
"Do not overwrite this query from
1929 outside the window" below the query textarea. Then you can browse
1930 tables/databases in the background without losing the contents of the
1931 textarea, so this is especially useful when composing a query with
1932 tables you first have to look in. The checkbox will get automatically
1933 checked whenever you change the contents of the textarea. Please
1934 uncheck the button whenever you definitely want the query window to
1935 get updated even though you have made alterations.
1937 If
<tt>$cfg['QueryHistoryDB']
</tt> is set to
<tt>TRUE
</tt> you can specify the amount of
1938 saved history items using
<tt>$cfg['QueryHistoryMax']
</tt>.
1940 The query window also has a custom tabbed look to group the features.
1941 Using the variable
<tt>$cfg['QueryWindowDefTab']
</tt> you can specify the
1942 default tab to be used when opening the query window. It can be set to
1943 either 'sql', 'files', 'history' or 'full'.

1968 where you edit x/y coordinates of those elements you can activate a
1969 scratchboard where all your elements are placed. By clicking on an
1970 element, you can move them around in the pre-defined area and the x/y
1971 coordinates will get updated dynamically. Likewise, when entering a
1972 new position directly into the input field, the new position in the
1973 scratchboard changes after your cursor leaves the input field.
<br />
1974 You have to click on the 'OK'-button below the tables to save the new
1975 positions. If you want to place a new element, first add it to the
1976 table of elements and then you can drag the new element around.
<br />
1977 By changing the paper size and the orientation you can change the size
1978 of the scratchboard as well. You can do so by just changing the
1979 dropdown field below, and the scratchboard will resize automatically,
1980 without interfering with the current placement of the elements.

">File structure</a></li>
2213 <h3 id="transformationsintro
">1. Introduction</h3>
2215 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2216 and the proper directives. Please see the <a href="#config
">Configuration
2217 section</a> on how to do so.</p>
2219 <p> You can apply different transformations to the contents of each field. The
2220 transformation will take the content of each field and transform it with
2221 certain rules defined in the selected transformation.</p>
2223 <p> Say you have a field 'filename' which contains a filename. Normally you would
2224 see in phpMyAdmin only this filename. Using transformations you can transform
2225 that filename into a HTML link, so you can click inside of the phpMyAdmin
2226 structure on the field's link and will see the file displayed in a new browser
2227 window. Using transformation options you can also specify strings to
2228 append/prepend to a string or the format you want the output stored in.</p>
2230 <p> For a general overview of all available transformations and their options,
2231 you can consult your
2232 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2235 <p> For a tutorial on how to effectively use transformations, see our
2236 <a href="http://www.phpmyadmin.net/home_page/docs.php
">Link section</a> on
2237 the official phpMyAdmin homepage.</p>
2239 <h3 id="transformationshowto
">2. Usage</h3>
2241 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2242 clicking on the 'Structure' link for a table). There click on
2243 "Change" (or change icon) and there you will see three new fields at
2244 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2245 'Transformation options'.</p>
2247 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2248 that corresponds to the column's contents. Please note that
2249 transformations are inactive as long as no MIME-type is selected.</li>
2251 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2252 hopefully growing amount of pre-defined transformations. See below for information on
2253 how to build your own transformation.<br />
2255 There are global transformations and mimetype-bound transformations. Global transformations
2256 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2257 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2258 transformations which operate on the main mimetype (like 'image'), which will most likely
2259 take the subtype into regard, and those who only operate on a
2260 specific subtype (like 'image/jpeg').<br />
2262 You can use transformations on mimetypes for which the function was not defined for. There
2263 is no security check for you selected the right transformation, so take care of what the
2264 output will be like.</li>
2266 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2267 transform-function specific options here. Usually the transforms can operate with default
2268 options, but it is generally a good idea to look up the overview to see which options are
2271 Much like the ENUM/SET-Fields, you have to split up several options using the format
2272 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2273 parsed as an array, leaving the first value the first element in the array, and so
2276 If you want to specify a MIME character set you can define it in the transformation_options.
2277 You have to put that outside of the pre-defined options of the specific mime-transform,
2278 as the last value of the set. Use the format "'; charset=XXX'
". If you use a transform,
2279 for which you can specify 2 options and you want to append a character set, enter "'first
2280 parameter','second parameter','charset=us-ascii'
". You can, however use the defaults for
2281 the parameters: "'','','charset=us-ascii'
".</li>
2284 <h3 id="transformationsfiles
">3. File structure</h3>
2286 <p> All mimetypes and their transformations are defined through single files in
2287 the directory 'libraries/transformations/'.</p>
2289 <p> They are stored in files to ease up customization and easy adding of new
2290 transformations.</p>
2292 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2293 always work. It makes no sense to apply a transformation to a mimetype, the
2294 transform-function doesn't know to handle.</p>
2296 <p> One can, however, use empty mime-types and global transformations which should work
2297 for many mimetypes. You can also use transforms on a different mimetype they where built
2298 for, but pay attention to option usage as well as what the transformation does to your
2301 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2302 any other transform function and provides some basic functions.</p>
2304 <p> There are 5 possible file names:</p>
2306 <ol><li>A mimetype+subtype transform:<br /><br />
2308 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2310 Please not that mimetype and subtype are separated via '_', which shall
2311 not be contained in their names. The transform function/filename may
2312 contain only characters which cause no problems in the file system as
2313 well as the PHP function naming convention.<br /><br />
2315 The transform function will the be called
2316 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2318 <b>Example:</b><br /><br />
2320 <tt>text_html__formatted.inc.php</tt><br />
2321 <tt>PMA_transform_text_html__formatted()</tt></li>
2323 <li>A mimetype (w/o subtype) transform:<br /><br />
2325 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2327 Please note that there are no single '_' characters.
2328 The transform function/filename may contain only characters which cause
2329 no problems in the file system as well as the PHP function naming
2330 convention.<br /><br />
2332 The transform function will the be called
2333 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2335 <b>Example:</b><br /><br />
2337 <tt>text__formatted.inc.php</tt><br />
2338 <tt>PMA_transform_text__formatted()</tt></li>
2340 <li>A mimetype+subtype without specific transform function<br /><br />
2342 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2344 Please note that there are no '__' characters in the filename. Do not
2345 use special characters in the filename causing problems with the file
2348 No transformation function is defined in the file itself.<br /><br />
2350 <b>Example:</b><br /><br />
2352 <tt>text_plain.inc.php</tt><br />
2355 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2357 <tt>[mimetype].inc.php</tt><br /><br />
2359 Please note that there are no '_' characters in the filename. Do not use
2360 special characters in the filename causing problems with the file system.
2363 No transformation function is defined in the file itself.<br /><br />
2365 <b>Example:</b><br /><br />
2367 <tt>text.inc.php</tt><br />
2370 <li>A global transform function with no specific mimetype<br /><br />
2372 <tt>global__[transform].inc.php</tt><br /><br />
2374 The transform function will the be called
2375 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2377 <b>Example:</b><br /><br />
2379 <tt>global__formatted</tt><br />
2380 <tt>PMA_transform_global__formatted()</tt></li>
2383 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2384 transform function.</p>
2386 <p> All filenames containing no '__' in themselves are not shown as valid transform
2387 functions in the dropdown.</p>
2389 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2390 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2391 without a transform function. Also note the introduction of a function description in
2392 the language files. For each function a $strTransformation_[filename without .inc.php]
2395 <p> You can use the template generator to generate new functions and entries in the
2398 <p> To create a new transform function please see
2399 <tt>libraries/transformations/template_generator.sh</tt>.
2400 To create a new, empty mimetype please see
2401 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2403 <p> A transform function always gets passed three variables:</p>
2405 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2406 you want to transform.</li>
2407 <li><b>$options</b> - Contains any user-passed options to a transform function
2409 <li><b>$meta</b> - Contains an object with field information to your column.
2410 The data is drawn from the output of the
2411 <a href="http://www.php.net/mysql_fetch_field
">mysql_fetch_field()</a>
2412 function. This means, all object properties described on the
2413 <a href="http://www.php.net/mysql_fetch_field
">manual page</a> are
2414 available in this variable and can be used to transform a field accordingly
2415 to unsigned/zerofill/not_null/... properties.<br />
2416 The $meta->mimetype variable contains the original MIME-type of the
2417 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>

2527 the system default is <i>/tmp</i>).<br />
2528 We recommend the following setup for Apache servers running in safe mode,
2529 to enable uploads of files while being reasonably secure:</p>
2531 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2532 <li>give ownership to the Apache server's user.group:

">1.16 I cannot upload big dump files (memory,

2616 <p> Starting with version 2.7.0, the import engine has been re–written and these
2617 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2618 to take advantage of the new import features.</p>
2620 <p> The first things to check (or ask your host provider to check) are the
2621 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2622 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2623 All of these three settings limit the maximum size of data that can be
2624 submitted and handled by PHP. One user also said that post_max_size
2625 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2627 There exist several workarounds if your upload is too big or your
2628 hosting provider is unwilling to change the settings:</p>
2630 <ul><li>Look at the <a href="#cfg_UploadDir
" class="configrule
">$cfg['UploadDir']</a>
2631 feature. This allows one to
2632 upload a file to the server via scp, ftp, or your favorite file transfer
2633 method. PhpMyAdmin is then able to import the files from the temporary
2634 directory. More information is available in the <a href="#config
">Configuration
2635 section</a> of this document.</li>
2636 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php
">
2637 BigDump</a>) to split the files before uploading. We cannot support this
2638 or any third party applications, but are aware of users having success
2640 <li>If you have shell (command line) access, use MySQL to import the files
2641 directly. You can do this by issuing the "source" command from

2673 <p> You tried to access MySQL with an old MySQL client library. The version of
2674 your MySQL client library can be checked in your phpinfo() output.

2677 <abbr title="Frequently Asked Questions
">FAQ</abbr> 1.17</a>.<br /><br />
2679 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2680 changed the authentication hash and your PHP is trying to use the old method.
2681 The proper solution is to use the <a href="http://www.php.net/mysqli
">mysqli extension</a>
2682 with the proper client library to match your MySQL installation. Your
2683 chosen extension is specified in <a href="#cfg_Servers_extension

2712 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2713 "MySQL extension". This extension may be part of the PHP
2714 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2715 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2716 to load the extension but failed.<br /><br />
2718 Usually, the problem is solved by installing a software package called
2719 "PHP-MySQL" or something similar.</p>

">1.23 I'm running MySQL on a Win32 machine. Each time I create

2739 <p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
2740 defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
2741 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2742 Just edit your <tt>my.ini</tt> file that should be located in your Windows

2887 you need mod_rewrite to be enabled. Then you just need to create following

">1.37 I run phpMyAdmin on cluster of different machines and
2921 password encryption in cookie auth doesn't work.</a></h4>
2923 <p> If your cluster consist of different architectures, PHP code used for
2924 encryption/decryption won't work correct. This is caused by use of

">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work,</a></h4>
2952 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />
2953 Example from the Apache 2.2 documentation:</p>
2955 ProxyPass /mirror/foo/ http://backend.example.com/
2956 ProxyPassReverse /mirror/foo/ http://backend.example.com/
2957 ProxyPassReverseCookieDomain backend.example.com public.example.com
2958 ProxyPassReverseCookiePath / /mirror/foo/
2961 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
2962 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
2963 This is not specific to phpmyadmin, it's just the behavior of Apache.
2967 ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin

3004 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3006 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3007 In your <i>php.ini</i> you will find a line</p>
3009 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3011 <p> change it to</p>
3013 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3015 <p> Then restart apache and it will work.</p>
3017 <p> Here is a fix suggested by Brad Ummer:</p>
3019 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3020 To do this, telnet to your server and go to the MySQL bin directory. In
3021 this directory there should be a file named <i>mysqladmin</i>. Type
3022 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3023 info about your MySQL server, including the socket
3024 (<i>/tmp/mysql.sock</i>, for example).</li>
3025 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3026 phpMyAdmin, you need to complete the socket information in the
3027 <i>config.inc.php</i>.<br />
3029 <a href="#cfg_Servers_socket
" class="configrule
">
3030 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3033 Please also make sure that the permissions of this file allow to be readable
3034 by your webserver (i.e. '0755').</li>
3037 <p> Have also a look at the

3066 <p> When you are using a port on your localhost, which you redirect via
3067 port-forwarding to another host, MySQL is not resolving the localhost
3069 Erik Wasser explains: The solution is: if your host is "localhost"
3070 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
3071 connection for speeding up things. And that doesn't work in this configuration
3072 with port forwarding.<br />

3083 Under <a href="#cfg_ThemePath

3084 should not delete the directory "original" or its underlying

3197 <p> The invalid part of the code is the horizontal line made of dashes that

3232 I get series of errors like "Warning: unable to parse url". How
3233 can this be fixed?</a></h4>
3235 Your table neither have a primary key nor an unique one, so we must use a
3236 long expression to identify this row. This causes problems to parse_url
3237 function. The workaround is to create a primary or unique key.

">3.8 I cannot use (clickable) HTML-forms in fields where I put

3245 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3246 nested forms can be put inside the table where phpMyAdmin displays the results.
3247 You can, however, use any form inside of a table if keep the parent
3248 form-container with the target to tbl_row_delete.php and just put your own
3249 input-elements inside. If you use a custom submit input field, the form will
3250 submit itself to the displaying page again, where you can validate the
3251 $HTTP_POST_VARS in a transformation.

3337 If you're running a server which cannot be accessed by other people, it's

3339 (with Apache you can use

3347 Your

</i> file should be
<tt>chmod

3350 All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
3351 is a user whose password is only known to you, and apache is the
3352 group under which Apache runs.
3355 You should use PHP safe mode, to protect from other users that try

3915 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3916 on them. Otherwise you could just put a comment on the field. Because entering
3917 your own mimetype will cause serious syntax checking issues and validation,
3918 this introduces a high-risk false-user-input situation. Instead you have to
3919 initialize mimetypes using functions or empty mimetype definitions.

3920 Plus, you have a whole overview of available mimetypes. Who knows all those
3921 mimetypes by heart so he/she can enter it at will?

"faqbookmark">
3924 <a href=
"#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
3925 can't I see any bookmarks below the query box? What is this variable for?
3928 <p> Any query you have executed can be stored as a bookmark on the page where the
3929 results are displayed. You will find a button labeled 'Bookmark this query'
3930 just at the end of the page.
<br />
3931 As soon as you have stored a bookmark, it is related to the database you run
3932 the query on. You can now access a bookmark dropdown on each page, the query
3933 box appears on for that database.
<br /><br />
3935 Since phpMyAdmin
2.5.0 you are also able to store variables for the bookmarks.
3936 Just use the string
<b>/*[VARIABLE]*/
</b> anywhere in your query. Everything
3937 which is put into the
<i>value
</i> input box on the query box page will
3938 replace the string
"/*[VARIABLE]*/
" in your stored query. Just be
3939 aware of that you HAVE to create a valid query, otherwise your query won't be
3940 even able to be stored in the database.
<br />
3941 Also remember, that everything else inside the
<b>/*[VARIABLE]*/
</b> string
3942 for your query will remain the way it is, but will be stripped of the /**/
3943 chars. So you can use:
<br /><br />
3945 <code>/*, [VARIABLE] AS myname */
</code><br /><br />
3947 which will be expanded to
<br /><br />
3949 <code>, VARIABLE as myname
</code><br /><br />
3951 in your query, where VARIABLE is the string you entered in the input box. If
3952 an empty string is provided, no replacements are made.
<br /><br />
3954 A more complex example. Say you have stored this query:
<br /><br />
3955 <code>SELECT Name, Address FROM addresses WHERE
1 /* AND Name LIKE '%[VARIABLE]%' */
</code>
3958 Say, you now enter
"phpMyAdmin
" as the variable for the stored query,
3959 the full query will be:
<br /><br />
3961 <code>SELECT Name, Address FROM addresses WHERE
1 AND Name LIKE '%phpMyAdmin%'
</code>
3964 You can use multiple occurrences of
<b>/*[VARIABLE]*/
</b> in a single query.
<br />
3965 <b>NOTE THE ABSENCE OF SPACES
</b> inside the
"/**/
" construct. Any
3966 spaces inserted there
3967 will be later also inserted as spaces in your query and may lead to unexpected
3968 results especially when
3969 using the variable expansion inside of a
"LIKE ''
" expression.
<br />
3970 Your initial query which is going to be stored as a bookmark has to yield at
3971 least one result row so
3972 you can store the bookmark. You may have that to work around using well
3973 positioned
"/**/
" comments.

4013 You will see two lists of values, the first list containing the key

4015 and the key. The reason for this is to be able to type the first
4016 letter of either the key or the display field.

</a></h4>
4082 <p> First, for general information about BLOB streaming on MySQL, visit
<a href=
"http://blobstreaming.org">blobstreaming.org
</a>. We currently support streaming if you are running MySQL
5.1 with the PBXT and PBMS storage engines.
</p>
4085 <li>In
<tt>config.inc.php
</tt> your host should be defined with a FQDN (fully qualified domain name) instead of something like
"localhost
".
</li>
4086 <li>A current limitation is that your first login via phpMyAdmin to a freshly-started server must be done with an account that has the SUPER privilege.
</li>
4087 <li>On your target database, go to Operations and in the
"BLOB Repository
" section, click
"Enable
". This creates the PBMS system tables inside your database.
</li>
4088 <li>Ensure that your target table is under the PBXT storage engine and has a LONGBLOB column.
</li>
4089 <li>When you insert or update a row in this table, put a checkmark on the
"Upload to BLOB repository
" optional choice; otherwise, the upload will be done directly in your column instead of the repository.
</li>
4090 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example
"View image
". A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time but in case it's incorrect, it's possible to edit it by clicking on the displayed MIME-type.

4160 <p> If you use Apache web server, phpMyAdmin exports information about
4161 authentication to Apache environment and it can be used in Apache logs.
4162 Currently there are two variables available:
4165 <dt><code>userID
</code></dt>
4166 <dd>User name of currently active user (he does not have to be logged
4168 <dt><code>userStatus
</code></dt>
4169 <dd>Status of currently active user, one of
<code>ok
</code> (user is
4170 logged in),
<code>mysql-denied
</code> (MySQL denied user login),
4171 <code>allow-denied
</code> (user denied by allow/deny rules),
4172 <code>root-denied
</code> (root is denied in configuration),
4173 <code>empty-denied
</code> (empty password is denied).
4176 <code>LogFormat
</code> directive for Apache can look like following:
4179 LogFormat
"%h %l %u %t \"%r\
" %>s %b \
4180 \"%{Referer}i\
" \"%{User-Agent}i\
" %{userID}n %{userStatus}n" pma_combined
4183 You can then use any log analyzing tools to detect possible break in

4190 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
4191 great features have been written by other people and you too can help to
4192 make phpMyAdmin a useful tool.
</p>
4194 <p> If you're planning to contribute source, please read the following
4197 <ul><li>All files include
<i>libraries/header.inc.php
</i> (layout),.
4198 <i>libraries/common.lib.php
</i> (common functions) and
4199 <i>config.inc.php
</i>.
<br />
4200 Only configuration data should go in
<i>config.inc.php
</i>. Please keep
4201 it free from other code.
<br />
4202 Commonly used functions should be added to
4203 <i>libraries/common.lib.php
</i> and more specific ones may be added
4204 within a library stored into the
<i>libraries
</i> sub-directory.
</li>
4205 <li>Obviously, you're free to use whatever coding style you want. But
4206 please try to keep your code as simple as possible: beginners are
4207 using phpMyAdmin as an example application.
<br />
4208 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4209 compliant on one hand, they fit the
4210 <a href=
"http://pear.php.net/">
4211 <abbr title=
"PHP Extension and Application Repository">PEAR
</abbr>
4212 coding standards
</a>
4213 on the other hand. Please pay attention to this.
</li>
4214 <li>Please try to keep up the file-naming conventions. Table-related stuff
4215 goes to
<i>tbl_*.php
</i>, db-related code to
<i>db_*.php
</i>,
4216 server-related tools to
<i>server_*.php
</i> and so on.
</li>
4217 <li>Please don't put message strings in your code, instead add the string
4218 (at least) to
<i>english-utf-
8.inc.php
</i> and print() it out.
</li>
4219 <li>If you want to be really helpful, write an entry for the ChangeLog.

4427 Original Credits of Version
2.1.0
4428 ---------------------------------
4430 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4431 to create a web-based interface to MySQL using PHP3. Although I have not
4432 used any of his source-code, there are some concepts I've borrowed from
4433 him. phpMyAdmin was created because Peter told me he wasn't going to
4434 further develop his (great) tool.
4436 - Amalesh Kempf
<ak-lsml_at_living-source.com
> who contributed the
4437 code for the check when dropping a table or database. He also suggested
4438 that you should be able to specify the primary key on tbl_create.php3. To
4439 version
1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4440 well as a bug-report. Plus many smaller improvements.
4441 - Jan Legenhausen
<jan_at_nrw.net
>: He made many of the changes that
4442 were introduced in
1.3.0 (including quite significant ones like the
4443 authentication). For
1.4.1 he enhanced the table-dump feature. Plus
4445 - Marc Delisle
<DelislMa_at_CollegeSherbrooke.qc.ca
> made phpMyAdmin
4446 language-independent by outsourcing the strings to a separate file. He
4447 also contributed the French translation.
4448 - Alexandr Bravo
<abravo_at_hq.admiral.ru
> who contributed
4449 tbl_select.php3, a feature to display only some fields from a table.
4450 - Chris Jackson
<chrisj_at_ctel.net
> added support for MySQL
4451 functions in tbl_change.php3. He also added the
4452 "Query by Example
" feature in
2.0.
4453 - Dave Walton
<walton_at_nordicdms.com
> added support for multiple
4454 servers and is a regular contributor for bug-fixes.
4455 - Gabriel Ash
<ga244_at_is8.nyu.edu
> contributed the random access
4457 The following people have contributed minor changes, enhancements, bugfixes
4458 or support for a new language:
4459 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4460 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4461 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4464 And thanks to everyone else who sent me email with suggestions, bug-reports
4465 and or just some feedback.
