96 <!-- INTRODUCTION -->
99 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
100 a single database. To accomplish the latter you'll need a properly set up
101 MySQL user who can read/write only the desired database. It's up to you to
102 look up the appropriate part in the MySQL manual.

151 </li>
153 </ul>
156 <p> Many people have difficulty
157 understanding the concept of user management with regards to phpMyAdmin. When
158 a user logs in to phpMyAdmin, that username and password are passed directly
159 to MySQL. phpMyAdmin does no account management on its own (other than
160 allowing one to manipulate the MySQL user account information); all users
161 must be valid MySQL users.</p>
170 <!-- INSTALLATION -->
178 </ol>
181 phpMyAdmin does not apply any special security methods to the MySQL database
182 server. It is still the system administrator's job to grant permissions on
184 be used for this.
185 </p>
193 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
194 before uploading them to your server, as PHP seems not to like
199 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
200 Downloads page. Some kits contain only the English messages,
201 others contain all languages in UTF-8 format (this should be fine
202 in most situations), others contain all
203 languages and all character sets. We'll assume you chose a kit whose
205 </li>
206 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
208 document root. If you don't have direct access to your document root,
209 put the files in a directory on your local machine, and, after step 4,
210 transfer the directory on your web server using, for example, ftp.</li>
211 <li>Ensure that all the scripts have the appropriate owner (if PHP is
212 running in safe mode, having some scripts with an owner different
213 from the owner of other scripts will be a
218 <li>Now you must configure your installation. There are two methods that
219 can be used. Traditionally, users have hand-edited a copy of
221 provided for those who prefer a graphical installation. Creating a
222 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
223 <ul><li>To manually create the file, simply use your text editor to
226 file) in the main (top-level) phpMyAdmin directory (the one
230 default value is okay for a particular setting, there is no
232 few directives to get going, a simple configuration may look
233 like this:
234 <pre>
235 <?php
236 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
238 $i=0;
239 $i++;
240 $cfg['Servers'][$i]['auth_type'] = 'cookie';
241 ?>
242 </pre>
243 Or, if you prefer to not be prompted every time you log in:
244 <pre>
245 <?php
247 $i=0;
248 $i++;
249 $cfg['Servers'][$i]['user'] = 'root';
250 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
251 $cfg['Servers'][$i]['auth_type'] = 'config';
252 ?>
253 </pre>
254 For a full explanation of possible configuration values, see the
260 directory. This is a security measure. On a Linux/Unix system you
261 can use the following commands:
262 <pre>
263 cd phpMyAdmin
264 mkdir config # create directory for saving
265 chmod o+rw config # give it world writable permissions
266 </pre>
267 And to edit an existing configuration, copy it over first:
268 <pre>
269 cp config.inc.php config/ # copy current configuration for editing
270 chmod o+w config/config.inc.php # give it world writable permissions
271 </pre>
272 On other platforms, simply create the folder and ensure that your
281 the webserver does not have the proper permissions you may see the
283 config/</tt> directory exists and has the proper permissions -
285 and upload (via FTP or some similar means) to the proper location.<br /><br />
287 Once the file has been saved, it must be moved out of the <tt>
288 config/</tt> directory and the permissions must be reset, again
289 as a security measure:
290 <pre>
291 mv config/config.inc.php . # move file to current directory
292 chmod o-rw config.inc.php # remove world read and write permissions
293 rm -rf config # remove not needed directory
294 </pre>
295 Now the file is ready to be used. You can choose to review or edit
296 the file with your favorite editor, if you prefer to set some
297 advanced options which the setup script does not provide.</li></ul></li>
298 <li>If you are using the
300 protect the phpMyAdmin installation directory because using
301 config does not require a user to
302 enter a password to access the phpMyAdmin installation. Use of an alternate
303 authentication method is recommended, for example with
311 in your browser. phpMyAdmin should now display a welcome screen
312 and your databases, or a login dialog if using
314 authentication mode.</li>
317 Apache you can use supplied <a href="#glossary"><i>.htaccess</i></a> file in that folder, for other
318 webservers, you should configure this yourself. Such configuration
319 prevents from possible path exposure and cross side scripting
320 vulnerabilities that might happen to be found in that code.</li>
321 <li>
322 It is generally good idea to protect public phpMyAdmin installation
323 against access by robots as they usually can not do anything good
325 your webserver or limit access by web server configuration, see
327 </li>
328 </ol>
332 <p> For a whole set of new features (bookmarks, comments,
334 tracking mechanism,
336 transformation, etc.) you need to create a set of special tables. Those
337 tables can be located in your own database, or in a central database for a
338 multi-user installation (this database would then be accessed by the
339 controluser, so no other user should have rights to it).</p>
350 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
351 that you may need special (administrator) privileges to create the database
352 and tables, and that the script may need some tuning, depending on the
353 database name.</p>
358 section</a>. You will also need to have a controluser with the proper rights
365 unpacked one. Configuration files from old versions may
366 require some tweaking as some options have been changed or removed; in
368 so you better remove it from your file and just use the default one.

386 them to play around with others.<br />
387 Nevertheless be aware that MS Internet Explorer seems to be really buggy
391 that your user/password pair are not in clear in the configuration file.
392 </li>
395 authentication modes are more secure: the MySQL login information does
396 not need to be set in the phpMyAdmin configuration file (except possibly
398 However, keep in mind that the password travels in plain text, unless
399 you are using the HTTPS protocol.<br />
400 In cookie mode, the password is stored, encrypted with the blowfish

963 table, which column is to be displayed as a tool-tip when moving the
964 cursor over the corresponding key.<br />
965 This configuration variable will hold the name of this special
966 table. To allow the usage of this functionality:
968 <li>put the table name in
970 'pma_table_info')</li>
971 <li>then for each table where you want to use this feature,
973 to choose the column.</li>

1007 Since release 2.3.0 you can store comments to describe each column for

1011 Starting with release 2.5.0, comments are consequently used on the table
1012 property pages and table browse view, showing up as tool-tips above the
1013 column name (properties page) or embedded within the header of table in
1014 browse view. They can also be shown in a table dump. Please see the
1015 relevant configuration directives later on.<br /><br />
1017 Also new in release 2.5.0 is a MIME-transformation system which is also
1019 Transformations</a> for further information. To use the
1020 MIME-transformation system, your column_info table has to have the three
1021 new columns 'mimetype', 'transformation', 'transformation_options'.

1051 don't want to use a table-based history, you can use the JavaScript-based
1052 history. Using that, all your history items are deleted when closing the
1053 window.<br /><br />
1055 Using
1057 you can specify an amount of history items you want to have on hold. On
1058 every login, this list gets cut to the maximum amount.<br /><br />
1060 The query history is only available if JavaScript is enabled in your
1061 browser.<br /><br />

1076 Since release 3.5.0 you can show recently used tables in the left navigation frame.
1077 It helps you to jump across table directly, without the need to select the database,
1078 and then select the table. Using
1080 you can configure the maximum number of recent tables shown. When you select a table
1081 from the list, it will jump to the page specified in
1082 <a href="#cfg_LeftDefaultTabTable" class="configrule">$cfg['LeftDefaultTabTable']</a>.<br/><br/>
1084 Without configuring the storage, you can still access the recently used tables,
1085 but it will disappear after you logout.<br/><br/>

1099 Since release 3.5.0 phpMyAdmin can be configured to remember several things
1100 (sorted column
1102 , column order, and column visibility from a database table) for browsing tables.
1103 Without configuring the storage, these features still can be used,
1104 but the values will disappear after you logout.<br/><br/>
1106 To allow the usage of these functionality persistently:
1108 <ul>

1118 Since release 3.3.x a tracking mechanism is available.
1120 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1121 and data definition statements. After enabling it you can create versions of tables.
1122 <br/><br/>
1123 The creation of a version has two effects:
1125 <ul>
1127 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1128 </ul>
1130 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1131 For the report you can use filters, for example you can get a list of statements within a date range.
1132 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1133 In addition you can export the (filtered) report to a file or to a temporary database.

2203 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2204 or icon is always displayed on the left panel. If JavaScript is enabled in
2205 your browser, a click on this opens a distinct query window, which is
2206 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2207 changes to display a query box.<br /><br />

2218 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
2219 query in the right panel's query box.
2220 <br /><br />
2221 The usage of the JavaScript query window is recommended if you have a
2222 JavaScript enabled browser. Basic functions are used to exchange quite
2223 a few variables, so most 4th generation browsers should be capable to
2224 use that feature. It currently is only tested with Internet Explorer 6

2233 When using the JavaScript based query window, it will always get
2234 updated when you click on a new table/db to browse and will focus if
2235 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2236 the query window by checking the box "Do not overwrite this query from
2237 outside the window" below the query textarea. Then you can browse
2238 tables/databases in the background without losing the contents of the
2239 textarea, so this is especially useful when composing a query with
2240 tables you first have to look in. The checkbox will get automatically
2241 checked whenever you change the contents of the textarea. Please
2242 uncheck the button whenever you definitely want the query window to
2243 get updated even though you have made alterations.

2439 <!-- TRANSFORMATIONS -->
2445 </ol>
2449 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2451 section</a> on how to do so.</p>
2453 <p> You can apply different transformations to the contents of each column. The
2454 transformation will take the content of each column and transform it with
2455 certain rules defined in the selected transformation.</p>
2457 <p> Say you have a column 'filename' which contains a filename. Normally you would
2458 see in phpMyAdmin only this filename. Using transformations you can transform
2459 that filename into a HTML link, so you can click inside of the phpMyAdmin
2460 structure on the column's link and will see the file displayed in a new browser
2461 window. Using transformation options you can also specify strings to
2462 append/prepend to a string or the format you want the output stored in.</p>
2464 <p> For a general overview of all available transformations and their options,
2465 you can consult your
2466 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2467 installation.</p>
2469 <p> For a tutorial on how to effectively use transformations, see our
2471 the official phpMyAdmin homepage.</p>
2475 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2476 clicking on the 'Structure' link for a table). There click on
2477 "Change" (or change icon) and there you will see three new
2478 fields at
2479 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2480 'Transformation options'.</p>
2482 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2483 that corresponds to the column's contents. Please note that
2484 transformations are inactive as long as no MIME-type is selected.</li>
2486 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2487 hopefully growing amount of pre-defined transformations. See below for information on
2488 how to build your own transformation.<br />
2490 There are global transformations and mimetype-bound transformations. Global transformations
2491 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2492 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2493 transformations which operate on the main mimetype (like 'image'), which will most likely
2494 take the subtype into regard, and those who only operate on a
2495 specific subtype (like 'image/jpeg').<br />
2497 You can use transformations on mimetypes for which the function was not defined for. There
2498 is no security check for you selected the right transformation, so take care of what the
2499 output will be like.</li>
2501 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2502 transform-function specific options here. Usually the transforms can operate with default
2503 options, but it is generally a good idea to look up the overview to see which options are
2504 necessary.<br />
2506 Much like the ENUM/SET-Fields, you have to split up several options using the format
2507 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2508 parsed as an array, leaving the first value the first element in the array, and so
2509 forth.<br />
2511 If you want to specify a MIME character set you can define it in the transformation_options.
2512 You have to put that outside of the pre-defined options of the specific mime-transform,
2514 for which you can specify 2 options and you want to append a character set, enter "'first
2515 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2517 </ul>
2521 <p> All mimetypes and their transformations are defined through single files in
2522 the directory 'libraries/transformations/'.</p>
2524 <p> They are stored in files to ease up customization and easy adding of new
2525 transformations.</p>
2527 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2528 always work. It makes no sense to apply a transformation to a mimetype the
2529 transform-function doesn't know to handle.</p>
2531 <p> One can, however, use empty mime-types and global transformations which should work
2532 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2533 for, but pay attention to option usage as well as what the transformation does to your
2534 column.</p>
2536 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2537 any other transform function and provides some basic functions.</p>
2539 <p> There are 5 possible file names:</p>
2541 <ol><li>A mimetype+subtype transform:<br /><br />
2543 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2545 Please not that mimetype and subtype are separated via '_', which shall
2546 not be contained in their names. The transform function/filename may
2547 contain only characters which cause no problems in the file system as
2548 well as the PHP function naming convention.<br /><br />
2550 The transform function will the be called
2551 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2553 <b>Example:</b><br /><br />
2555 <tt>text_html__formatted.inc.php</tt><br />
2556 <tt>PMA_transform_text_html__formatted()</tt></li>
2558 <li>A mimetype (w/o subtype) transform:<br /><br />
2560 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2562 Please note that there are no single '_' characters.
2563 The transform function/filename may contain only characters which cause
2564 no problems in the file system as well as the PHP function naming
2565 convention.<br /><br />
2567 The transform function will the be called
2568 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2570 <b>Example:</b><br /><br />
2572 <tt>text__formatted.inc.php</tt><br />
2573 <tt>PMA_transform_text__formatted()</tt></li>
2575 <li>A mimetype+subtype without specific transform function<br /><br />
2577 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2579 Please note that there are no '__' characters in the filename. Do not
2580 use special characters in the filename causing problems with the file
2581 system.<br /><br />
2583 No transformation function is defined in the file itself.<br /><br />
2585 <b>Example:</b><br /><br />
2587 <tt>text_plain.inc.php</tt><br />
2588 (No function)</li>
2590 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2592 <tt>[mimetype].inc.php</tt><br /><br />
2594 Please note that there are no '_' characters in the filename. Do not use
2595 special characters in the filename causing problems with the file system.
2596 <br /><br />
2598 No transformation function is defined in the file itself.<br /><br />
2600 <b>Example:</b><br /><br />
2602 <tt>text.inc.php</tt><br />
2603 (No function)</li>
2605 <li>A global transform function with no specific mimetype<br /><br />
2607 <tt>global__[transform].inc.php</tt><br /><br />
2609 The transform function will the be called
2610 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2612 <b>Example:</b><br /><br />
2614 <tt>global__formatted</tt><br />
2615 <tt>PMA_transform_global__formatted()</tt></li>
2616 </ol>
2618 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2619 transform function.</p>
2621 <p> All filenames containing no '__' in themselves are not shown as valid transform
2622 functions in the dropdown.</p>
2624 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2625 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2626 without a transform function.</p>
2628 <p> To create a new transform function please see
2629 <tt>libraries/transformations/template_generator.sh</tt>.
2630 To create a new, empty mimetype please see
2631 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2633 <p> A transform function always gets passed three variables:</p>
2635 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2636 you want to transform.</li>
2637 <li><b>$options</b> - Contains any user-passed options to a transform function
2638 as an array.</li>
2639 <li><b>$meta</b> - Contains an object with information about your column.

2753 <p> Your uploaded file is saved by PHP in the "upload dir", as
2754 defined in <i>php.ini</i> by the variable <tt>upload_tmp_dir</tt> (usually
2755 the system default is <i>/tmp</i>).<br />
2756 We recommend the following setup for Apache servers running in safe mode,
2757 to enable uploads of files while being reasonably secure:</p>
2759 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2760 <li>give ownership to the Apache server's user.group:

2810 were named <tt>user</tt> and <tt>password</tt>. Please modify your column
2811 names to align with current standards.</p>
2816 </h4>
2818 <p> Starting with version 2.7.0, the import engine has been re–written and these
2819 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2820 to take advantage of the new import features.</p>
2822 <p> The first things to check (or ask your host provider to check) are the
2823 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2824 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2825 All of these three settings limit the maximum size of data that can be
2826 submitted and handled by PHP. One user also said that
2827 <tt>post_max_size</tt>
2828 and <tt>memory_limit</tt> need to be larger than <tt>upload_max_filesize</tt>.<br /> <br />
2830 There exist several workarounds if your upload is too big or your
2831 hosting provider is unwilling to change the settings:</p>

2835 upload a file to the server via scp, ftp, or your favorite file transfer

2840 BigDump</a>) to split the files before uploading. We cannot support this
2841 or any third party applications, but are aware of users having success
2842 with it.</li>
2843 <li>If you have shell (command line) access, use MySQL to import the files
2844 directly. You can do this by issuing the "source" command from
2845 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2846 </ul>
2850 support?</a></h4>
2852 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2853 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2854 connect to your MySQL server using PHP's classic
2857 is available in PHP 5.0. The latter one should be used unless you have a
2858 good reason not to do so.<br />
2859 When compiling PHP, we strongly recommend that you manually link the MySQL
2860 extension of your choice to a MySQL client library of at least the same
2861 minor version since the one that is bundled with some PHP distributions is
2865 (versions 5.1 and 5.2 were tested).<br /><br />

2871 message, "Client does not support authentication protocol requested
2872 by server; consider upgrading MySQL client"</a></h5>
2874 <p> You tried to access MySQL with an old MySQL client library. The version of
2875 your MySQL client library can be checked in your phpinfo() output.
2876 In general, it should have at least the same minor version as your server

2905 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2906 "MySQL extension". This extension may be part of the PHP
2907 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2908 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2909 to load the extension but failed.<br /><br />

2912 "PHP-MySQL" or something similar.</p>

2932 <p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
2933 defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
2934 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2935 Just edit your <tt>my.ini</tt> file that should be located in your Windows
2936 directory and add the following line to the group [mysqld]:</p>
2938 <pre>set-variable = lower_case_table_names=0</pre>
2940 <p> Next, save the file and restart the MySQL service. You can always check the
2941 value of this directive using the query</p>

2959 </pre>
2961 <p> as this version of mod_gzip on Apache (Windows) has problems handling

2989 <p> This can happen due to a MySQL bug when having database / table names with
2990 upper case characters although <tt>lower_case_table_names</tt> is set to 1.
2991 To fix this, turn off this directive, convert all database and table names
2992 to lower case and turn it on again. Alternatively, there's a bug-fix
2993 available starting with MySQL 3.23.56 / 4.0.11-gamma.</p>

2999 <p> It is possible to configure Apache in such a way that PHP has problems
3000 interpreting .php files.</p>
3002 <p> The problems occur when two different (and conflicting) set of directives
3003 are used:</p>

3016 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
3017 The recommended way is with <tt>AddType</tt>, so just comment out
3018 the first set of lines and restart Apache:</p>

3106 password encryption in cookie auth doesn't work.</a></h4>
3108 <p> If your cluster consist of different architectures, PHP code used for
3109 encryption/decryption won't work correct. This is caused by use of
3110 pack/unpack functions in code. Only solution is to use mcrypt extension
3111 which works fine in this case.</p>
3116 <p> Yes but the default configuration values of Suhosin are known to cause
3117 problems with some operations, for example editing a table with many
3118 columns and no primary key or with textual primary key.
3119 </p>
3120 <p>
3121 Suhosin configuration might lead to malfunction in some cases and it can
3122 not be fully avoided as phpMyAdmin is kind of application which needs to
3123 transfer big amounts of columns in single HTTP request, what is something
3124 what Suhosin tries to prevent. Generally all
3125 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3126 <code>suhosin.get.*</code> directives can have negative effect on
3127 phpMyAdmin usability. You can always find in your error logs which limit
3128 did cause dropping of variable, so you can diagnose the problem and adjust
3129 matching configuration variable.
3130 </p>
3131 <p>
3132 The default values for most Suhosin configuration options will work in most
3133 scenarios, however you might want to adjust at least following parameters:

3162 <a href="#faq1_40">1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.</a></h4>
3164 <p>To be able to use cookie auth Apache must know that it has to rewrite the set-cookie headers.<br />

3171 </pre>
3173 <p>Note: if the backend url looks like http://host/~user/phpmyadmin,
3174 the tilde (~) must be url encoded as %7E in the ProxyPassReverse* lines.
3175 This is not specific to phpmyadmin, it's just the behavior of Apache.

3256 In your <i>php.ini</i> you will find a line</p>
3258 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3260 <p> change it to</p>
3262 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3264 <p> Then restart apache and it will work.</p>
3266 <p> Here is a fix suggested by Brad Ummer:</p>
3268 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3269 To do this, telnet to your server and go to the MySQL bin directory. In
3270 this directory there should be a file named <i>mysqladmin</i>. Type
3271 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3272 info about your MySQL server, including the socket
3273 (<i>/tmp/mysql.sock</i>, for example).</li>
3274 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3275 phpMyAdmin, you need to complete the socket information in the
3276 <i>config.inc.php</i>.<br />
3277 For example:
3279 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
3280 <br /><br />
3282 Please also make sure that the permissions of this file allow to be readable
3283 by your webserver (i.e. '0755').</li>
3284 </ul>
3286 <p> Have also a look at the
3288 corresponding section of the MySQL documentation</a>.</p>
3292 what can I do?</a></h4>
3295 directive to <tt>FALSE</tt> in the phpMyAdmin configuration file. It helps
3296 sometime.<br />
3297 Also have a look at your PHP version number: if it contains "b" or "alpha"
3298 it means you're running a testing version of PHP. That's not a so good idea,
3299 please upgrade to a plain revision.</p>
3303 or a table, an error 404 (page not found) is displayed or, with <abbr title="HyperText Transfer Protocol">HTTP</abbr> or
3304 cookie authentication, I'm asked to log in again. What's wrong?</a></h4>
3306 <p> Check the value you set for the
3308 directive in the phpMyAdmin configuration file.</p>
3312 password: YES)"-error when trying to access a MySQL-Server on a
3313 host which is port-forwarded for my localhost.</a></h4>
3315 <p> When you are using a port on your localhost, which you redirect via
3316 port-forwarding to another host, MySQL is not resolving the localhost
3317 as expected.<br />
3318 Erik Wasser explains: The solution is: if your host is "localhost"
3319 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3320 connection for speeding up things. And that doesn't work in this configuration
3321 with port forwarding.<br />
3327 <p> Themes are configured with
3331 <br />
3333 should not delete the directory "original" or its underlying
3334 structure, because this is the system theme used by phpMyAdmin.
3335 "original" contains all images and styles, for backwards
3336 compatibility and for all themes that would not include images or css-files.
3337 <br /><br />
3340 is enabled, you can select your favorite theme on the main page. Your
3341 selected theme will be stored in a cookie.<br /><br /></p>
3343 <p> To create a theme:</p>
3345 <ul><li>make a new subdirectory (for example "your_theme_name") under
3347 (by default <tt>themes</tt>)</li>
3348 <li>copy the files and directories from "original" to
3349 "your_theme_name"</li>
3350 <li>edit the css-files in "your_theme_name/css"</li>
3351 <li>put your new images in "your_theme_name/img"</li>
3352 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
3353 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
3354 contain your chosen theme name, that will be visible in user interface</li>
3355 <li>make a new screenshot of your theme and save it under
3356 "your_theme_name/screen.png"</li>
3357 </ul>
3359 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3360 theme verbose name, theme generation and theme version. These versions and
3361 generations are enumerated from 1 and do not have any direct dependence on
3362 phpMyAdmin version. Themes within same generation should be backwards
3363 compatible - theme with version 2 should work in phpMyAdmin requiring
3364 version 1. Themes with different generation are incompatible.</p>
3366 <p> If you do not want to use your own symbols and buttons, remove the
3367 directory "img" in "your_theme_name". phpMyAdmin will
3368 use the default icons and buttons (from the system-theme "original").
3369 </p>
3373 what can I do?</a></h4>
3375 <p> Here are a few points to check:</p>
3377 <ul><li>In <tt>config.inc.php</tt>, try to leave the
3379 directive empty. See also
3381 </li>
3382 <li>Maybe you have a broken PHP installation or you need to upgrade
3383 your Zend Optimizer. See
3385 http://bugs.php.net/bug.php?id=31134</a>.
3386 </li>
3387 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
3388 set to the default (200) or another low value, you could get this
3389 error if your table has a high number of columns. Adjust this setting
3390 accordingly. (Thanks to Klaus Dorninger for the hint).
3391 </li>
3392 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
3393 of ";" will cause this error. Replace it with "&;".
3394 </li>
3396 you might want to increase
3398 </li>
3399 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
3400 </li>
3401 </ul>
3406 <p> To be able to see a progress bar during your uploads, your server must
3409 one. Moreover, the JSON extension has to be enabled in your PHP.</p>
3410 <p> If using APC, you must set <tt>apc.rfc1867</tt> to <tt>on</tt> in your php.ini.</p>
3417 who logged out can not log in again in with the same nick.</a></h4>
3419 <p> This is related to the authentication mechanism (protocol) used by
3420 phpMyAdmin. To bypass this problem: just close all the opened
3421 browser windows and then go back to phpMyAdmin. You should be able to
3422 log in again.</p>
3426 limit error or a time limit error.</a></h4>
3428 <p> Compressed dumps are built in memory and because of this are limited to
3429 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3430 using
3432 (enabled by default). Zip exports can not be handled this way, so if you need
3433 Zip files for larger dump, you have to use another way.</p>
3437 when I rename a table or a column.</a></h4>
3439 <p> This is an InnoDB bug, see <a href="http://bugs.mysql.com/bug.php?id=21704">http://bugs.mysql.com/bug.php?id=21704</a>.</p>
3443 bundled with the MySQL server distribution.</a></h4>
3445 <p> The problem is that older versions of <code>mysqldump</code> created invalid comments like this:</p>
3447 <pre>
3448 -- MySQL dump 8.22
3449 --
3450 -- Host: localhost Database: database
3451 ---------------------------------------------------------
3452 -- Server version 3.23.54
3453 </pre>
3455 <p> The invalid part of the code is the horizontal line made of dashes that
3456 appears once in every dump created with mysqldump. If you want to run your
3457 dump you have to turn it into valid MySQL. This means, you have to add a
3458 whitespace after the first two dashes of the line or add a # before it:
3459 <br />
3460 <code>
3461 -- -------------------------------------------------------<br />
3462 </code>
3463 or<br />
3464 <code>
3465 #---------------------------------------------------------
3466 </code>
3467 </p>
3474 <p> Please note that you should not use the separating string multiple times
3475 without any characters between them, or at the beginning/end of your table
3476 name. If you have to, think about using another TableSeparator or disabling
3477 that feature</p>

3483 or having more than one index column in the foreign key.<br /><br/>

3485 LEFT JOIN from the foreign table.<br /><br/>
3486 </p>
3490 I get series of errors like "Warning: unable to parse url". How
3491 can this be fixed?</a></h4>
3492 <p>
3493 Your table neither have a primary key nor an unique one, so we must use a
3494 long expression to identify this row. This causes problems to parse_url
3495 function. The workaround is to create a primary or unique key.
3496 <br />
3497 </p>
3501 a MIME-Transformation onto!</a></h4>
3503 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3504 nested forms can be put inside the table where phpMyAdmin displays the results.
3505 You can, however, use any form inside of a table if keep the parent
3506 form-container with the target to tbl_row_delete.php and just put your own
3507 input-elements inside. If you use a custom submit input field, the form will
3508 submit itself to the displaying page again, where you can validate the
3509 $HTTP_POST_VARS in a transformation.
3511 For a tutorial on how to effectively use transformations, see our
3513 on the official phpMyAdmin-homepage.</p>
3517 MySQL server</a></h4>
3519 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3522 http://dev.mysql.com/doc/mysql/en/ansi-mode.html</a>). Most important of all,
3523 the quote-character (") is interpreted as an identifier quote character and
3524 not as a string quote character, which makes many internal phpMyAdmin
3526 statements. There is no workaround to this behaviour. News to this item will
3527 be posted in Bug report
3528 <a href="https://sourceforge.net/tracker/index.php?func=detail&aid=816858&group_id=23067&atid=377408">#816858</a>

3533 more that one column with the same value
3534 (for example <tt>SELECT lastname from employees where firstname like 'A%'</tt> and two "Smith" values are displayed),
3535 if I click Edit I cannot be sure that I am editing the intended row.</a></h4>
3537 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3538 can use it for the Edit and Delete links.</p>
3543 <p> phpMyAdmin uses a quick method to get the row count, and this method
3544 only returns an approximate count in the case of InnoDB tables. See
3546 a way to modify those results, but
3547 this could have a serious impact on performance.</p>

3598 Currently, the import type-detection system can only assign these MySQL types to columns. In future, more will likely be added but for the time being
3599 you will have to edit the structure to your liking post-import.
3600 <br /><br />
3601 Also, you should note the fact that phpMyAdmin will use the size of the largest item in any given column as the column size for the appropriate type. If you
3602 know you will be adding larger items to that column then you should manually adjust the column sizes accordingly. This is done for the sake of efficiency.

4054 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
4055 <p>
4058 <br /><br />
4059 Then you need to think about your schema layout. Which tables will go on
4060 which pages?
4061 </p>
4062 <ul>
4068 page and click Go. If you like, you
4070 linked tables onto the new page.</li>
4071 <li>Select the name of the new page (making sure the Edit radio button
4072 is selected) and click Go.</li>
4074 Coordinates are relative; your diagram will
4075 be automatically scaled to fit the page. When initially placing tables
4076 on the page, just pick any coordinates -- say, 50x50. After clicking
4078 position the element correctly.</li>
4080 first be sure to click the Save
4081 button beneath the list of tables and coordinates, to save any changes
4082 you made there. Then scroll all the way down, select the
4084 you want, and click Go.</li>
4085 <li>Internet Explorer for Windows may suggest an incorrect filename when
4090 browsers on Windows, do not have this problem.</li>
4091 </ul>
4095 columns!</a></h4>
4097 <p> No, it's MySQL that is doing
4103 underscores in the database name?</a></h4>
4105 <p> If you do not put a backslash before the underscore, this is a wildcard
4108 john2db ...<br /><br />
4110 If you put a backslash before the underscore, it means that the database
4111 name will have a real underscore.</p>
4115 statistics pages?</a></h4>
4126 if it already exists during the import. It does NOT drop the table after
4127 your export, it only affects the import file.</li>
4129 Otherwise, you may get an error if the table name exists but has a
4130 different structure.</li>
4132 (if any) will be included in backup.</li>
4134 column and table names formed with special characters are protected.</li>
4136 types set in the pmadb in the dump as
4138 </li>
4139 </ul>
4144 command, for better documentation (but resulting file is bigger).</li>
4146 once the INSERT verb and the table name.</li>
4149 </li>
4151 more info is provided in the
4153 but basically with this selected, invalid values are adjusted and
4154 inserted rather than causing the entire statement to fail.</li>
4155 </ul>
4159 in its name.</a></h4>
4162 is the normal way to reference a database and table name. Worse, MySQL
4163 will usually let you create a database with a dot, but then you cannot
4164 work with it, nor delete it.</p>
4170 <p>
4171 To use SQL Validator, you need PHP with
4177 module.
4178 </p>
4180 <p>
4186 usage.
4187 </p>
4189 <p>
4190 If you use the Validator, you should be aware that any
4192 submit will be stored anonymously (database/table/column names,
4193 strings, numbers replaced with generic values). The Mimer
4196 We utilize it as free SOAP service.
4197 </p>
4201 it, but MySQL says "BLOB column '...' used in key specification without
4204 <p> The right way to do this, is to create the column without any indexes,
4206 dialog. On this page, you will be able to choose your BLOB column, and
4207 set a size to the index, which is the condition to create an index on
4208 a BLOB column.</p>
4212 editing fields?</a></h4>
4214 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4215 with many editing fields (table structure changes, row editing, etc.).</p>
4219 WTF is this feature then useful for?</a></h4>
4221 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4222 on them. Otherwise you could just put a comment on the column. Because entering
4223 your own mimetype will cause serious syntax checking issues and validation,
4224 this introduces a high-risk false-user-input situation. Instead you have to
4225 initialize mimetypes using functions or empty mimetype definitions.<br />
4226 Plus, you have a whole overview of available mimetypes. Who knows all those
4227 mimetypes by heart so he/she can enter it at will?</p>
4231 can't I see any bookmarks below the query box? What is this variable for?
4232 </a></h4>
4234 <p> Any query you have executed can be stored as a bookmark on the page where the
4235 results are displayed. You will find a button labeled 'Bookmark this query'
4236 just at the end of the page.<br />
4237 As soon as you have stored a bookmark, it is related to the database you run
4238 the query on. You can now access a bookmark dropdown on each page, the query
4239 box appears on for that database.<br /><br />
4241 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4245 aware of that you HAVE to create a valid query, otherwise your query won't be
4246 even able to be stored in the database.<br />
4248 for your query will remain the way it is, but will be stripped of the /**/
4249 chars. So you can use:<br /><br />
4253 which will be expanded to<br /><br />
4257 in your query, where VARIABLE is the string you entered in the input box. If
4258 an empty string is provided, no replacements are made.<br /><br />
4260 A more complex example. Say you have stored this query:<br /><br />
4262 <br /><br />
4265 the full query will be:<br /><br />
4268 <br /><br />
4270 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4272 spaces inserted there
4273 will be later also inserted as spaces in your query and may lead to unexpected
4274 results especially when
4276 Your initial query which is going to be stored as a bookmark has to yield at
4277 least one result row so
4278 you can store the bookmark. You may have that to work around using well
4282 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
4283 include exported table?</a></h4>
4285 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
4286 document should look like following one (assuming you have table
4289 <pre>
4290 \documentclass{article} % or any class you want
4291 \usepackage{longtable} % for displaying table
4292 \begin{document} % start of document
4293 \include{table} % including exported table
4294 \end{document} % end of document
4295 </pre>
4299 access them.
4300 </a></h4>
4302 <p> You have one of these global privileges: CREATE
4303 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
4304 enable users to see all the database names.
4307 So if your users do not need those privileges, you can remove them and their
4308 databases list will shorten.</p>
4312 possible values for a column, based on some foreign table?</a></h4>
4314 <p> You have to setup appropriate links between the tables, and also
4318 foreign table, a drop-down list of values will be available.
4319 You will see two lists of values, the first list containing the key
4320 and the display column, the second list containing the display column
4321 and the key. The reason for this is to be able to type the first
4322 letter of either the key or the display column.<br /><br />
4324 For 100 values or more, a distinct window will appear, to browse foreign
4325 key values and choose one. To change the default limit of 100, see
4326 <tt><a href="#cfg_ForeignKeyMaxLimit" class="configrule">$cfg['ForeignKeyMaxLimit']</a></tt>.</p>
4330 automatically when entering Browse mode for a table?</a></h4>
4332 <p> Yes. If a bookmark has the same label as a table name and it's not a public bookmark, it will be executed.
4333 </p>
4338 <p> You can use
4340 which works out of the box.<br />
4341 Since phpMyAdmin 3.4.5 support for direct export to Microsoft Excel
4342 version 97 and newer was dropped.
4343 </p>
4347 what happens to my column comments stored in pmadb?</a></h4>
4349 <p> Automatic migration of a table's pmadb-style column comments to the native
4350 ones is done whenever you enter Structure page for this table.</p>
4355 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4356 <ul>
4359 later)</li>
4362 </ul>
4366 <ol>
4367 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of "localhost".</li>
4368 <li>Ensure that your target table is under the <tt>PBXT</tt> storage engine and has a <tt>LONGBLOB</tt> column (which must be nullable if you want to remove the BLOB reference from it).</li>
4369 <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 LONGBLOB column instead of the repository.</li>
4370 <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.</li>
4371 </ol>
4376 <p> Click the first row of the range, hold the shift key and click the last row of the range. This works everywhere you see rows, for example in Browse mode or on the Structure page.</p>
4382 <p>
4383 In all places where phpMyAdmin accepts format strings, you can use
4386 expanded variables depend on a context (for example, if you haven't chosen a
4387 table, you can not get the table name), but the following variables can be used:
4388 </p>
4389 <dl>
4395 <dd>Verbose MySQL server name as defined in <a href="#cfg_Servers_verbose">server configuration</a></dd>
4406 </dl>
4411 <p>
4412 By clicking on the button 'toggle scratchboard' on the page
4413 where you edit x/y coordinates of those elements you can activate a
4414 scratchboard where all your elements are placed. By clicking on an
4415 element, you can move them around in the pre-defined area and the x/y
4416 coordinates will get updated dynamically. Likewise, when entering a
4417 new position directly into the input field, the new position in the
4418 scratchboard changes after your cursor leaves the input field.
4419 </p>
4420 <p>
4421 You have to click on the 'OK'-button below the tables to save the new
4422 positions. If you want to place a new element, first add it to the
4423 table of elements and then you can drag the new element around.
4424 </p>
4425 <p>
4426 By changing the paper size and the orientation you can change the size
4427 of the scratchboard as well. You can do so by just changing the
4428 dropdown field below, and the scratchboard will resize automatically,
4429 without interfering with the current placement of the elements.
4430 </p>
4431 <p>
4432 If ever an element gets out of range you can either enlarge the paper
4433 size or click on the 'reset' button to place all elements below each
4434 other.
4435 </p>
4440 <p> Not every table can be put to the chart. Only tables with one, two or three columns can be visualised as a chart. Moreover the table must be in a special format for chart script to understand it. Currently supported formats can be found in the <a href="http://wiki.phpmyadmin.net/pma/Charts#Data_formats_for_query_results_chart">wiki</a>.</p>
4445 <p>
4446 An ESRI Shapefile is actually a set of several files, where .shp file contains
4447 geometry data and .dbf file contains data related to those geometry data.
4448 To read data from .dbf file you need to have PHP compiled with the dBase extension
4449 (--enable-dbase). Otherwise only geometry data will be imported.
4450 </p>
4453 <ul>
4454 <li>
4455 <p>
4456 Configure upload directory with
4458 .shp and .dbf files with the same filename and chose the .shp file from the import page.
4459 </p>
4460 </li>
4461 <li>
4462 <p>
4463 Create a Zip archive with .shp and .dbf files and import it. For this to work,
4466 </p>
4469 <pre>
4470 cd phpMyAdmin
4471 mkdir tmp
4472 chmod o+rwx tmp
4473 </pre>
4474 </li>
4475 </ul>
4481 <img src="themes/original/img/pmd/help_relation.png" width="100" height="100" alt="[relation icon]" /><br />
4482 The display column is shown in pink. To set/unset a column as the display column, click the "Choose column to display" icon, then click on the appropriate column name.</p>
4487 <p> The Zoom search feature is an alternative to table search feature. It allows you to explore
4488 a table by representing its data in a scatter plot. You can locate this feature by selecting
4489 a table and clicking the 'Search' tab. One of the sub-tabs in the 'Table Search' page is
4490 'Zoom Search'. <br/><br/>
4494 for example, id and town_code. The id values will be represented on one axis and town_code
4495 values on the other axis. Each row will be represented as a point in a scatter plot based
4496 on its id and town_code. You can include two additional search criteria apart from the two
4497 fields to display.<br/><br/>
4499 You can choose which field should be displayed as label for each point. If a display
4502 You can also select the maximum number of rows you want to be displayed in the plot by
4503 specifing it in the 'Max rows to plot' field. Once you have decided over your criteria,
4504 click 'Go' to display the plot.<br/><br/>
4506 After the plot is generated, you can use the mousewheel to zoom in and out of the plot.
4507 In addition, panning feature is enabled to navigate through the plot. You can zoom-in to
4508 a certail level of detail and use panning to locate your area of interest. Clicking on a
4509 point opens a dialogue box, displaying field values of the data row represented by the point.
4510 You can edit the values if required and click on submit to issue an update query. Basic
4511 instructions on how to use can be viewed by clicking the 'How to use?' link located just above
4512 the plot.</p>

4553 <p> Please refer to
4554 <a href="http://www.phpmyadmin.net/home_page/security.php">http://www.phpmyadmin.net/home_page/security.php</a>
4555 </p>
4560 <p> If you use Apache web server, phpMyAdmin exports information about
4561 authentication to the Apache environment and it can be used in Apache logs.
4562 Currently there are two variables available:
4563 </p>
4564 <dl>
4566 <dd>User name of currently active user (he does not have to be logged
4567 in).</dd>
4574 </dl>
4575 <p>
4577 </p>
4578 <pre>
4581 </pre>
4582 <p>
4583 You can then use any log analyzing tools to detect possible break-in
4584 attempts.
4585 </p>
4591 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4592 It allows you to connect to local as well as remote servers. This requires you to enter
4593 server host name, username, password, port and the name of the database. Therefore you can
4594 now synchronize your databases placed on the same server or some remote server.
4595 </p>
4597 <p>
4598 This feature is helpful for developers who need to replicate their
4599 database’s structure as well as data. Moreover, this feature not only
4600 helps replication but also facilitates the user to keep his/her database
4601 in sync with another database. Other than the full database, certain
4602 tables of the databases can also be synchronized.
4603 </p>
4605 <p>
4606 You need to fill in the host name of the server, the username and
4607 password of an user account already there in MySQL. Port is by default
4608 populated with 3306 (MySQL default port). Then the name of the database
4609 should be mentioned at the end. All the information other than the port
4610 needs to be filled explicitly for the source as well as target servers.
4611 </p>
4613 <p>
4614 After successfully passing through the authentication phase, the source and
4615 target database table names will be displayed. It will be a tabular
4616 representation.
4617 </p>
4619 <p>
4620 On the left, are listed the source database table names. Some of the
4622 are only present in source database and they need to be added to the
4623 target database in order to synchronize the target database. The tables
4625 target database.
4626 </p>
4628 <p>
4629 On the right, are listed the target database table names. There are few
4631 means that these tables are to be created in target database in order to
4632 synchronize target database with source database. Some table names
4634 only present in target database and they will remain unchanged in the
4635 target database. The column in the middle shows the difference between
4636 the source and target corresponding tables.
4637 </p>
4639 <p>
4641 letters, indicating that either Structure or Data are not up to date. By
4642 clicking on them, they will turn grey, what means that they will be synchronized.
4643 </p>
4647 tables?</a></h4>
4649 <p>
4650 Yes. This aspect of synchronization is currently limited to small tables, and they
4651 must have a primary key.

4996 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4997 to create a web-based interface to MySQL using PHP3. Although I have not
4998 used any of his source-code, there are some concepts I've borrowed from
4999 him. phpMyAdmin was created because Peter told me he wasn't going to
5000 further develop his (great) tool.

5010 well as a bug-report. Plus many smaller improvements.
