91 <!-- INTRODUCTION -->
92 <h2 id="intro">Introduction</h2>
94 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
95 a single database. To accomplish the latter you'll need a properly set up
96 MySQL user who can read/write only the desired database. It's up to you to
97 look up the appropriate part in the MySQL manual.
98 </p>
100 <h3>Currently phpMyAdmin can:</h3>
102 <ul><li>browse and drop databases, tables, views, columns and indexes</li>
103 <li>create, copy, drop, rename and alter databases, tables, columns and
104 indexes</li>
105 <li>maintenance server, databases and tables, with proposals on server
106 configuration</li>
107 <li>execute, edit and bookmark any
108 <abbr title="structured query language">SQL</abbr>-statement, even
109 batch-queries</li>
110 <li>load text files into tables</li>
111 <li>create<a href="#footnote_1"><sup>1</sup></a> and read dumps of tables

150 <h4>A word about users:</h4>
151 <p> Many people have difficulty
152 understanding the concept of user management with regards to phpMyAdmin. When
153 a user logs in to phpMyAdmin, that username and password are passed directly
154 to MySQL. phpMyAdmin does no account management on its own (other than
155 allowing one to manipulate the MySQL user account information); all users
156 must be valid MySQL users.</p>
158 <p class="footnote" id="footnote_1">
159 <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
160 dumps and <abbr title="comma separated values">CSV</abbr> exports if you use
161 PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
162 (<tt>--with-bz2</tt>). Proper support may also need changes in
163 <tt>php.ini</tt>.</p>
165 <!-- INSTALLATION -->

173 </ol>
175 <p class="important">
176 phpMyAdmin does not apply any special security methods to the MySQL database
177 server. It is still the system administrator's job to grant permissions on
178 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
179 be used for this.
180 </p>
182 <p class="important">
183 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
184 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
185 <abbr title="operating system">OS</abbr> version before
186 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
187 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
188 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
189 before uploading them to your server, as PHP seems not to like
190 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
191 (&quot;<tt>\r</tt>&quot;).</p>
193 <h3 id="quick_install">Quick Install</h3>
194 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
195 Downloads page. Some kits contain only the English messages,
196 others contain all languages in UTF-8 format (this should be fine
197 in most situations), others contain all
198 languages and all character sets. We'll assume you chose a kit whose
199 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
200 </li>
201 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
202 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
203 document root. If you don't have direct access to your document root,
204 put the files in a directory on your local machine, and, after step 4,
205 transfer the directory on your web server using, for example, ftp.</li>
206 <li>Ensure that all the scripts have the appropriate owner (if PHP is
207 running in safe mode, having some scripts with an owner different
208 from the owner of other scripts will be a
209 problem). See <a href="#faq4_2">
210 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
211 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
212 1.26</a> for suggestions.</li>
213 <li>Now you must configure your installation. There are two methods that
214 can be used. Traditionally, users have hand-edited a copy of
215 <tt>config.inc.php</tt>, but now a wizard-style setup script is
216 provided for those who prefer a graphical installation. Creating a
217 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
218 <ul><li>To manually create the file, simply use your text editor to
219 create the file <tt>config.inc.php</tt> (you can copy
220 <tt>config.sample.inc.php</tt> to get minimal configuration
221 file) in the main (top-level) phpMyAdmin directory (the one
222 that contains <tt>index.php</tt>). phpMyAdmin first loads
223 <tt>libraries/config.default.php</tt> and then overrides those
224 values with anything found in <tt>config.inc.php</tt>. If the
225 default value is okay for a particular setting, there is no
226 need to include it in <tt>config.inc.php</tt>. You'll need a
227 few directives to get going, a simple configuration may look
228 like this:
229 <pre>
230 &lt;?php
231 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
233 $i=0;
234 $i++;
235 $cfg['Servers'][$i]['auth_type'] = 'cookie';
236 ?&gt;
237 </pre>
238 Or, if you prefer to not be prompted every time you log in:
239 <pre>
240 &lt;?php
242 $i=0;
243 $i++;
244 $cfg['Servers'][$i]['user'] = 'root';
245 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
246 $cfg['Servers'][$i]['auth_type'] = 'config';
247 ?&gt;
248 </pre>
249 For a full explanation of possible configuration values, see the
250 <a href="#config">Configuration Section</a> of this document.</li>
251 <li id="setup_script">Instead of manually editing
252 <tt>config.inc.php</tt>, you can use the
253 <a href="setup/">Setup Script</a>. First you must
254 manually create a folder <tt>config</tt> in the phpMyAdmin
255 directory. This is a security measure. On a Linux/Unix system you
256 can use the following commands:
257 <pre>
258 cd phpMyAdmin
259 mkdir config # create directory for saving
260 chmod o+rw config # give it world writable permissions
261 </pre>
262 And to edit an existing configuration, copy it over first:
263 <pre>
264 cp config.inc.php config/ # copy current configuration for editing
265 chmod o+w config/config.inc.php # give it world writable permissions
266 </pre>
267 On other platforms, simply create the folder and ensure that your
268 web server has read and write access to it. <a href="#faq1_26">FAQ
269 1.26</a> can help with this.<br /><br />
271 Next, open <tt><a href="setup/">setup/</a>
272 </tt>in your browser. Note that <strong>changes are not saved to
273 disk until explicitly choose <tt>Save</tt></strong> from the
274 <i>Configuration</i> area of the screen. Normally the script saves
275 the new config.inc.php to the <tt>config/</tt> directory, but if
276 the webserver does not have the proper permissions you may see the
277 error "Cannot load or save configuration." Ensure that the <tt>
278 config/</tt> directory exists and has the proper permissions -
279 or use the <tt>Download</tt> link to save the config file locally
280 and upload (via FTP or some similar means) to the proper location.<br /><br />
282 Once the file has been saved, it must be moved out of the <tt>
283 config/</tt> directory and the permissions must be reset, again
284 as a security measure:
285 <pre>
286 mv config/config.inc.php . # move file to current directory
287 chmod o-rw config.inc.php # remove world read and write permissions
288 rm -rf config # remove not needed directory
289 </pre>
290 Now the file is ready to be used. You can choose to review or edit
291 the file with your favorite editor, if you prefer to set some
292 advanced options which the setup script does not provide.</li></ul></li>
293 <li>If you are using the
294 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
295 protect the phpMyAdmin installation directory because using
296 config does not require a user to
297 enter a password to access the phpMyAdmin installation. Use of an alternate
298 authentication method is recommended, for example with
299 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
300 <tt>auth_type</tt> cookie or http. See the
301 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
302 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
303 information, especially <a href="#faq4_4">
304 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
305 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
306 in your browser. phpMyAdmin should now display a welcome screen
307 and your databases, or a login dialog if using
308 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
309 authentication mode.</li>
310 <li>You should deny access to the <tt>./libraries</tt> and
311 <tt>./setup/lib</tt> subfolders in your webserver configuration. For
312 Apache you can use supplied .htaccess file in that folder, for other
313 webservers, you should configure this yourself. Such configuration
314 prevents from possible path exposure and cross side scripting
315 vulnerabilities that might happen to be found in that code.</li>
316 <li>
317 It is generally good idea to protect public phpMyAdmin installation
318 against access by robots as they usually can not do anything good
319 there. You can do this using <code>robots.txt</code> file in root of
320 your webserver or limit access by web server configuration. You can
321 find example <code>.htaccess</code> file which can help you achieve
322 this in <code>contrib</code> directory in phpMyAdmin.
323 </li>
324 </ol>
326 <h3 id="linked-tables">phpMyAdmin configuration storage</h3>
328 <p> For a whole set of new features (bookmarks, comments,
329 <abbr title="structured query language">SQL</abbr>-history,
330 tracking mechanism,
331 <abbr title="Portable Document Format">PDF</abbr>-generation, column contents
332 transformation, etc.) you need to create a set of special tables. Those
333 tables can be located in your own database, or in a central database for a
334 multi-user installation (this database would then be accessed by the
335 controluser, so no other user should have rights to it).</p>
337 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
338 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
339 special attention to <a href="#faq1_23">
340 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
342 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
343 or newer, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>
344 and then create new tables by importing <i>./scripts/create_tables.sql</i>.</p>
346 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
347 that you may need special (administrator) privileges to create the database
348 and tables, and that the script may need some tuning, depending on the
349 database name.</p>
351 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
352 should specify the table names in your <i>./config.inc.php</i> file. The
353 directives used for that can be found in the <a href="#config">Configuration
354 section</a>. You will also need to have a controluser with the proper rights
355 to those tables (see section <a href="#authentication_modes">Using
356 authentication modes</a> below).</p>
358 <h3 id="upgrading">Upgrading from an older version</h3>
360 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
361 unpacked one. Configuration files from old versions may
362 require some tweaking as some options have been changed or removed; in
363 particular, the definition of <tt>$cfg['AttributeTypes']</tt> has changed
364 so you better remove it from your file and just use the default one.
365 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
366 statement that you might find near the end of your configuration file.</p>
368 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
369 over <tt>config.inc.php</tt> because the default configuration file
370 is version-specific.</p>
372 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
373 version 5.x or newer and if you use the phpMyAdmin configuration storage,
374 you should run the SQL script found in
375 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
377 <h3 id="authentication_modes">Using authentication modes</h3>
379 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
380 authentication modes are recommended in a <b>multi-user environment</b>
381 where you want to give users access to their own database and don't want
382 them to play around with others.<br />
383 Nevertheless be aware that MS Internet Explorer seems to be really buggy
384 about cookies, at least till version 6.<br />
385 Even in a <b>single-user environment</b>, you might prefer to use
386 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
387 that your user/password pair are not in clear in the configuration file.
388 </li>
390 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
391 authentication modes are more secure: the MySQL login information does
392 not need to be set in the phpMyAdmin configuration file (except possibly
393 for the <a href="#controluser">controluser</a>).<br />
394 However, keep in mind that the password travels in plain text, unless
395 you are using the HTTPS protocol.<br />
396 In cookie mode, the password is stored, encrypted with the blowfish
397 algorithm, in a temporary cookie.</li>
399 <li id="pmausr">Note: this section is only applicable if
400 your MySQL server is running with <tt>--skip-show-database</tt>.<br /><br />
402 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
403 modes, phpMyAdmin needs a controluser that has <b>only</b> the
404 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
405 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
406 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
407 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
408 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
409 file under the
410 <tt><a href="#cfg_Servers_controluser" class="configrule">
411 $cfg['Servers'][$i]['controluser']</a></tt> and
412 <tt><a href="#cfg_Servers_controlpass" class="configrule">
413 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
414 The following example assumes you want to use <tt>pma</tt> as the
415 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
416 only an example: use something else in your file!</b> Input these
417 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
418 client.<br />
419 Of course you have to replace <tt>localhost</tt> with the webserver's host
420 if it's not the same as the MySQL server's one.
422 <pre>
423 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
424 GRANT SELECT (
425 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
426 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
427 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
428 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
429 Execute_priv, Repl_slave_priv, Repl_client_priv
430 ) ON mysql.user TO 'pma'@'localhost';
431 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
432 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
433 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
434 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
436 If you want to use the many new relation and bookmark features:
438 <pre>
439 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
440 </pre>
442 (this of course requires that your <a href="#linked-tables">phpMyAdmin
443 configuration storage</a> be set up).
444 <br /></li>
446 <li>Then each of the <i>true</i> users should be granted a set of privileges
447 on a set of particular databases. Normally you shouldn't give global
448 privileges to an ordinary user, unless you understand the impact of those
449 privileges (for example, you are creating a superuser).<br />
450 For example, to grant the user <i>real_user</i> with all privileges on

465 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>
467 <ul><li>Uses <abbr title="HyperText Transfer Protocol">HTTP</abbr> Basic authentication
468 method and allows you to log in as any valid MySQL user.</li>
469 <li>Is supported with most PHP configurations. For

480 using the <i>.htaccess</i> mechanism along with

482 mode.</li>
483 </ul>
485 <h4>'cookie' authentication mode</h4>
487 <ul><li>You can use this method as a replacement for the
488 <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
489 (for example, if you're running
490 <abbr title="Internet Information Services">IIS</abbr>).</li>
491 <li>Obviously, the user must enable cookies in the browser, but this is
492 now a requirement for all authentication modes.</li>
493 <li>With this mode, the user can truly log out of phpMyAdmin and log in back
494 with the same username.</li>
495 <li>If you want to log in to arbitrary server see
496 <a href="#AllowArbitraryServer" class="configrule">
497 $cfg['AllowArbitraryServer']</a> directive.</li>
498 <li>As mentioned in the <a href="#require">requirements</a> section, having
499 the <tt>mcrypt</tt> extension will speed up access considerably, but is
500 not required.</li>
501 </ul>
503 <h4>'signon' authentication mode</h4>
505 <ul><li>This mode is a convenient way of using credentials from another
506 application to authenticate to phpMyAdmin.</li>
507 <li>The other application has to store login information into
508 session data.</li>
509 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
510 section.</li>
511 </ul>
512 <h4>'config' authentication mode</h4>
514 <ul><li>This mode is the less secure one because it requires you to fill the
515 <a href="#servers_user" class="configrule">
516 $cfg['Servers'][$i]['user']</a> and
517 <a href="#servers_user" class="configrule">
518 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
519 can read your config.inc.php can discover your username and password).
520 <br />
521 But you don't need to setup a &quot;controluser&quot; here: using the
522 <a href="#servers_only_db" class="configrule">
523 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
524 <li>In the <a href="#faqmultiuser">
525 <abbr title="Internet service provider">ISP</abbr>
526 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
527 is an entry explaining how to protect your configuration file.</li>
528 <li>For additional security in this mode, you may wish to consider the Host
529 authentication
530 <a href="#servers_allowdeny_order" class="configrule">
531 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
532 <a href="#servers_allowdeny_rules" class="configrule">
533 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
534 directives.</li>
535 <li>Unlike cookie and http, does not require a user to log in when first
536 loading the phpMyAdmin site. This is by design but could allow any
537 user to access your installation. Use of some restriction method is
538 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
539 HTTP-AUTH directive or disallowing incoming HTTP requests at
540 one&#8217;s router or firewall will suffice (both of which
541 are beyond the scope of this manual but easily searchable with Google).</li>
542 </ul>
543 <h4 id="swekey">Swekey authentication</h4>
545 The Swekey is a low cost authentication USB key that can be used in
546 web applications.<br /><br />
547 When Swekey authentication is activated, phpMyAdmin requires the
548 users's Swekey to be plugged before entering the login page (currently
549 supported for cookie authentication mode only). Swekey Authentication is
550 disabled by default.<br /><br />
551 To enable it, add the following line to <tt>config.inc.php</tt>:
552 </p>
553 <pre>
554 $cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';
555 </pre>
557 You then have to create the <tt>swekey.conf</tt> file that will associate
558 each user with their Swekey Id. It is important to place this file outside
559 of your web server's document root (in the example, it is located in <tt>/etc</tt>). A self documented sample file is provided
560 in the <tt>contrib</tt> directory. Feel free to use it with your own
561 users' information.<br /><br />
562 If you want to purchase a Swekey please visit
563 <a href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>
564 since this link provides funding for phpMyAdmin.

594 Don&#8217;t forget the trailing slash at the end.<br /><br />
596 Starting with version 2.3.0, it is advisable to try leaving this

600 A good test is to browse a table, edit a row and save it. There should
601 be an error message if phpMyAdmin is having trouble auto&#8211;detecting
602 the correct value. If you get an error that this must be set or if

643 no maximum length for this secret.<br /><br />
645 Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
646 makes a bit weaker security as this generated secret is stored in

648 cookie.</dd>
650 <dt id="cfg_Servers">$cfg['Servers'] array</dt>

843 If you want to have certain databases at the top, but don't care about the others, you do not
844 need to specify all other databases. Use:
845 <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>

998 Since release 2.3.0 you can store comments to describe each column for
999 each table. These will then be shown on the &quot;printview&quot;.
1000 <br /><br />
1002 Starting with release 2.5.0, comments are consequently used on the table
1003 property pages and table browse view, showing up as tool-tips above the
1004 column name (properties page) or embedded within the header of table in
1005 browse view. They can also be shown in a table dump. Please see the
1006 relevant configuration directives later on.<br /><br />
1008 Also new in release 2.5.0 is a MIME-transformation system which is also
1009 based on the following table structure. See <a href="#transformations">
1010 Transformations</a> for further information. To use the
1011 MIME-transformation system, your column_info table has to have the three
1012 new columns 'mimetype', 'transformation', 'transformation_options'.
1013 <br /><br />
1015 To allow the usage of this functionality:

1041 all queries you entered manually into the phpMyAdmin interface. If you
1042 don't want to use a table-based history, you can use the JavaScript-based
1043 history. Using that, all your history items are deleted when closing the
1044 window.<br /><br />
1046 Using
1047 <a href="#cfg_QueryHistoryMax" class="configrule">$cfg['QueryHistoryMax']</a>
1048 you can specify an amount of history items you want to have on hold. On
1049 every login, this list gets cut to the maximum amount.<br /><br />
1051 The query history is only available if JavaScript is enabled in your
1052 browser.<br /><br />
1054 To allow the usage of this functionality:

1067 Since release 3.5.0 you can show recently used tables in the left navigation frame.
1068 It helps you to jump across table directly, without the need to select the database,
1069 and then select the table. Using
1070 <a href="#cfg_LeftRecentTable" class="configrule">$cfg['LeftRecentTable']</a>
1071 you can configure the maximum number of recent tables shown. When you select a table
1072 from the list, it will jump to the page specified in
1073 <a href="#cfg_LeftDefaultTabTable" class="configrule">$cfg['LeftDefaultTabTable']</a>.<br/><br/>
1075 Without configuring the storage, you can still access the recently used tables,

1109 Since release 3.3.x a tracking mechanism is available.
1110 It helps you to track every <abbr title="structured query language">SQL</abbr> command which
1111 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1112 and data definition statements. After enabling it you can create versions of tables.
1113 <br/><br/>
1114 The creation of a version has two effects:
1116 <ul>
1117 <li>phpMyAdmin saves a snapshot of the table, including structure and indexes.</li>
1118 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1119 </ul>
1121 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1122 For the report you can use filters, for example you can get a list of statements within a date range.
1123 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1124 In addition you can export the (filtered) report to a file or to a temporary database.
1125 <br/><br/>
1127 To allow the usage of this functionality:
1129 <ul>

1376 when in Light mode.</dd>
1378 <dt id="cfg_MaxCharactersInDisplayedSQL">$cfg['MaxCharactersInDisplayedSQL'] integer</dt>
1379 <dd>The maximum number of characters when a SQL query is displayed. The
1380 default limit of 1000 should be correct to avoid the display of tons
1381 of hexadecimal codes that represent BLOBs, but some users have real
1382 SQL queries that are longer than 1000 characters. Also, if a query's
1383 length exceeds this limit, this query is not saved in the history.</dd>
1385 <dt id="cfg_OBGzip">$cfg['OBGzip'] string/boolean</dt>
1386 <dd>Defines whether to use GZip output buffering for increased
1387 speed in <abbr title="HyperText Transfer Protocol">HTTP</abbr> transfers.<br />
1388 Set to true/false for enabling/disabling. When set to 'auto' (string),
1389 phpMyAdmin tries to enable output buffering and will automatically disable
1390 it if your browser has some problems with buffering. IE6 with a certain patch
1391 is known to cause data corruption when having enabled buffering.</dd>

1400 <dt id="cfg_ExecTimeLimit">$cfg['ExecTimeLimit'] integer [number of seconds]</dt>
1401 <dd>Set the number of seconds a script is allowed to run. If seconds is set
1402 to zero, no time limit is imposed.<br />
1403 This setting is used while importing/exporting dump files and in the
1404 Synchronize feature but has no effect when PHP is running in safe mode.</dd>
1406 <dt id="cfg_SessionSavePath">$cfg['SessionSavePath'] string</dt>
1407 <dd>Path for storing session data (<a

1410 <dt id="cfg_MemoryLimit">$cfg['MemoryLimit'] string [number of bytes]</dt>
1411 <dd>Set the number of bytes a script is allowed to allocate. If set
1412 to zero, no limit is imposed.<br />
1413 This setting is used while importing/exporting dump files and at some
1414 other places in phpMyAdmin so you definitely don't want to put here
1415 a too low value. It has no effect when PHP is running in safe mode.<br />
1416 You can also use any string as in php.ini, eg. '16M'. Ensure
1417 you don't omit the suffix (16 means 16 bytes!)</dd>
1419 <dt id="cfg_SkipLockedTables">$cfg['SkipLockedTables'] boolean</dt>

1424 <dd>Defines whether <abbr title="structured query language">SQL</abbr> queries
1425 generated by phpMyAdmin should be displayed or not.</dd>
1427 <dt id="cfg_AllowUserDropDatabase">$cfg['AllowUserDropDatabase'] boolean</dt>
1428 <dd>Defines whether normal users (non-administrator) are allowed to
1429 delete their own database or not. If set as FALSE, the link &quot;Drop
1430 Database&quot; will not be shown, and even a &quot;DROP DATABASE
1431 mydatabase&quot; will be rejected. Quite practical for
1432 <abbr title="Internet service provider">ISP</abbr>'s with many
1433 customers.<br />
1434 Please note that this limitation of SQL queries is not as strict as
1435 when using MySQL privileges. This is due to nature of SQL queries
1436 which might be quite complicated. So this choice should be viewed as
1437 help to avoid accidental dropping rather than strict privilege
1438 limitation.</dd>
1440 <dt id="cfg_Confirm">$cfg['Confirm'] boolean</dt>
1441 <dd>Whether a warning (&quot;Are your really sure...&quot;) should be

1450 </dd>
1452 <dt id="cfg_LoginCookieValidity">$cfg['LoginCookieValidity'] integer [number of seconds]</dt>
1453 <dd>Define how long is login cookie valid. Please note that php
1454 configuration option <a href="http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime">session.gc_maxlifetime</a>
1455 might limit session validity and if session is lost, login cookie is
1456 also invalidated. So it is a good idea to set <code>session.gc_maxlifetime</code>
1457 not lower than the value of $cfg['LoginCookieValidity'].</dd>
1459 <dt id="cfg_LoginCookieStore">$cfg['LoginCookieStore'] integer [number of seconds]</dt>
1460 <dd>Define how long login cookie should be stored in browser. Default 0
1461 means that it will be kept for existing session. This is recommended
1462 for not trusted environments.</dd>
1464 <dt id="cfg_LoginCookieDeleteAll">$cfg['LoginCookieDeleteAll'] boolean</dt>
1465 <dd>If enabled (default), logout deletes cookies for all servers,
1466 otherwise only for current one. Setting this to false makes it easy to
1467 forget to log out from other server, when you are using more of
1468 them.</dd>
1470 <dt id="cfg_UseDbSearch">$cfg['UseDbSearch'] boolean</dt>

1483 <span id="cfg_AllowArbitraryServer">$cfg['AllowArbitraryServer']</span> boolean</dt>
1484 <dd>If enabled, allows you to log in to arbitrary servers using cookie auth and permits to specify servers of your choice in the Synchronize dialog.
1485 <br /><br />
1487 <b>NOTE:</b> Please use this carefully, as this may allow users access to
1488 MySQL servers behind the firewall where your

1498 <dt id="cfg_LeftFrameLight">$cfg['LeftFrameLight'] boolean</dt>
1499 <dd>Defines whether to use a select-based menu and display only the current
1500 tables in the left frame (smaller page). Only in Non-Lightmode you can
1501 use the feature to display nested folders using
1502 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1503 </dd>
1505 <dt id="cfg_LeftFrameDBTree">$cfg['LeftFrameDBTree'] boolean</dt>
1506 <dd>In light mode, defines whether to display the names of databases (in the
1507 selector) using a tree, see also
1508 <a href="#cfg_LeftFrameDBSeparator" class="configrule">$cfg['LeftFrameDBSeparator']</a>.
1509 </dd>
1511 <dt id="cfg_LeftFrameDBSeparator">$cfg['LeftFrameDBSeparator']
1512 string or array</dt>
1513 <dd>The string used to separate the parts of the database name when showing
1514 them in a tree. Alternatively you can specify more strings in an array
1515 and all of them will be used as a separator.</dd>
1517 <dt id="cfg_LeftFrameTableSeparator">$cfg['LeftFrameTableSeparator'] string</dt>
1518 <dd>Defines a string to be used to nest table spaces. Defaults to '__'.
1519 This means if you have tables like 'first__second__third' this will be
1520 shown as a three-level hierarchy like: first &gt; second &gt; third.
1521 If set to FALSE or empty, the feature is disabled. NOTE: You should
1522 not use this separator at the beginning or end of a

1524 characters in between.</dd>
1526 <dt id="cfg_LeftFrameTableLevel">$cfg['LeftFrameTableLevel'] string</dt>
1527 <dd>Defines how many sublevels should be displayed when splitting

1535 <dd>Defines whether to display table comment as tool-tip in left frame or
1536 not.</dd>
1538 <dt id="cfg_ShowTooltipAliasDB">$cfg['ShowTooltipAliasDB'] boolean</dt>
1539 <dd>If tool-tips are enabled and a DB comment is set, this will flip the
1540 comment and the real name. That means that if you have a table called
1541 'user0001' and add the comment 'MyName' on it, you will see the name
1542 'MyName' used consequently in the left frame and the tool-tip shows
1543 the real name of the DB.</dd>
1545 <dt id="cfg_ShowTooltipAliasTB">$cfg['ShowTooltipAliasTB'] boolean/string</dt>
1546 <dd>Same as <a href="#cfg_ShowTooltipAliasDB" class="configrule">$cfg['ShowTooltipAliasDB']</a>, except this works for table names.
1548 When setting this to 'nested', the Alias of the Tablename is only used
1549 to split/nest the tables according to the
1550 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1551 directive. So only the folder is called like the Alias, the tablename itself
1552 stays the real tablename.</dd>
1554 <dt id="cfg_LeftDisplayLogo">$cfg['LeftDisplayLogo'] boolean</dt>
1555 <dd>Defines whether or not to display the phpMyAdmin logo at the top of the left frame.

1568 integer</dt>
1569 <dd>Defines the minimum number of tables to display a JavaScript filter box above the
1570 list of tables in the left frame.
1571 Defaults to <tt>30</tt>. To disable the filter completely some high number

1580 <dt id="cfg_DisplayDatabasesList">$cfg['DisplayDatabasesList'] boolean or text</dt>
1581 <dd>Defines whether to display database choice in light navigation frame as links
1582 instead of in a drop-down. Defaults to 'auto' - on main page list is
1583 shown, when database is selected, only drop down is displayed.</dd>
1585 <dt id="cfg_LeftDefaultTabTable">$cfg['LeftDefaultTabTable'] string</dt>
1586 <dd>Defines the tab displayed by default when clicking the small
1587 icon next to each table name in the navigation panel. Possible

1592 <dt id="cfg_ShowStats">$cfg['ShowStats'] boolean</dt>
1593 <dd>Defines whether or not to display space usage and statistics about databases
1594 and tables.<br />
1595 Note that statistics requires at least MySQL 3.23.3 and that, at this
1596 date, MySQL doesn't return such information for Berkeley DB tables.</dd>
1598 <dt><span id="cfg_ShowServerInfo">$cfg['ShowServerInfo'] </span>boolean</dt>
1599 <dd>Defines whether to display detailed server information on main page.

1607 </dt>
1608 <dd>Defines whether to display the &quot;PHP information&quot; and
1609 &quot;Change password &quot; links and form for creating database or
1610 not at the starting main (right) frame. This setting
1611 does not check MySQL commands entered directly.<br /><br />
1613 Please note that to block the usage of phpinfo() in scripts, you
1614 have to put this in your <i>php.ini</i>:
1616 <pre>disable_functions = phpinfo()</pre>
1618 Also note that enabling the &quot;Change password &quot; link has no
1619 effect with &quot;config&quot; authentication mode: because of the
1620 hard coded password value in the configuration file, end users can't
1621 be allowed to change their passwords.</dd>

2084 files, see <a href="#faq1_11"><abbr title="Frequently Asked Questions">FAQ</abbr>
2085 1.11</a>.
2086 <br /><br />
2088 If the directory where phpMyAdmin is installed is subject to an
2089 <tt>open_basedir</tt> restriction, you need to create a
2090 temporary directory in some directory accessible by the web
2091 server. However for security reasons, this directory should be outside
2092 the tree published by webserver. If you cannot avoid having this
2093 directory published by webserver, place at least an empty
2094 <tt>index.html</tt> file there, so that directory listing is not
2095 possible.
2096 <br /><br />
2098 This directory should have as strict permissions as possible as the only
2099 user required to access this directory is the one who runs the
2100 webserver. If you have root privileges, simply make this user owner of
2101 this directory and make it accessible only by it:
2102 <br /><br />
2104 <pre>
2105 chown www-data:www-data tmp
2106 chmod 700 tmp
2107 </pre>
2109 If you cannot change owner of the directory, you can achieve a similar
2110 setup using <abbr title="Access Control List">ACL</abbr>:
2112 <pre>
2113 chmod 700 tmp
2114 setfacl -m "g:www-data:rwx" tmp
2115 setfacl -d -m "g:www-data:rwx" tmp
2116 </pre>
2118 If neither of above works for you, you can still make the directory
2119 <code>chmod 777</code>, but it might impose risk of other users on
2120 system reading and writing data in this directory.

2166 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2167 or icon is always displayed on the left panel. If JavaScript is enabled in
2168 your browser, a click on this opens a distinct query window, which is
2169 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2170 changes to display a query box.<br /><br />
2172 The size of this query window can be customized with
2173 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowHeight']</tt>
2174 - both integers for the size in pixels. Note that normally, those
2175 parameters will be modified in <tt>layout.inc.php</tt> for the
2176 theme you are using.<br /><br />
2178 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
2179 from the results page (in the &quot;Showing Rows&quot; section)
2180 opens the query window and puts the current query
2181 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
2182 query in the right panel's query box.
2183 <br /><br />
2184 The usage of the JavaScript query window is recommended if you have a
2185 JavaScript enabled browser. Basic functions are used to exchange quite
2186 a few variables, so most 4th generation browsers should be capable to
2187 use that feature. It currently is only tested with Internet Explorer 6
2188 and Mozilla 1.x.
2189 <br /><br />
2190 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
2191 to a table, which has to be created by you (see <a
2192 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
2193 all your queries will be appended to the form, but only as long as
2194 your window is opened they remain saved.
2195 <br /><br />
2196 When using the JavaScript based query window, it will always get
2197 updated when you click on a new table/db to browse and will focus if
2198 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2199 the query window by checking the box "Do not overwrite this query from
2200 outside the window" below the query textarea. Then you can browse
2201 tables/databases in the background without losing the contents of the
2202 textarea, so this is especially useful when composing a query with
2203 tables you first have to look in. The checkbox will get automatically
2204 checked whenever you change the contents of the textarea. Please
2205 uncheck the button whenever you definitely want the query window to
2206 get updated even though you have made alterations.
2207 <br /><br />
2208 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
2209 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
2210 <br /><br />
2211 The query window also has a custom tabbed look to group the features.
2212 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
2213 default tab to be used when opening the query window. It can be set to
2214 either 'sql', 'files', 'history' or 'full'.</dd>

2399 <h2 id="transformations">Transformations</h2>
2401 <ol><li><a href="#transformationsintro">Introduction</a></li>
2402 <li><a href="#transformationshowto">Usage</a></li>
2403 <li><a href="#transformationsfiles">File structure</a></li>
2404 </ol>
2406 <h3 id="transformationsintro">1. Introduction</h3>
2408 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2409 and the proper directives. Please see the <a href="#config">Configuration
2410 section</a> on how to do so.</p>
2412 <p> You can apply different transformations to the contents of each column. The
2413 transformation will take the content of each column and transform it with
2414 certain rules defined in the selected transformation.</p>
2416 <p> Say you have a column 'filename' which contains a filename. Normally you would
2417 see in phpMyAdmin only this filename. Using transformations you can transform
2418 that filename into a HTML link, so you can click inside of the phpMyAdmin
2419 structure on the column's link and will see the file displayed in a new browser
2420 window. Using transformation options you can also specify strings to
2421 append/prepend to a string or the format you want the output stored in.</p>
2423 <p> For a general overview of all available transformations and their options,
2424 you can consult your
2425 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2426 installation.</p>
2428 <p> For a tutorial on how to effectively use transformations, see our
2429 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2430 the official phpMyAdmin homepage.</p>
2432 <h3 id="transformationshowto">2. Usage</h3>
2434 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2435 clicking on the 'Structure' link for a table). There click on
2436 &quot;Change&quot; (or change icon) and there you will see three new
2437 fields at
2438 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2439 'Transformation options'.</p>
2441 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2442 that corresponds to the column's contents. Please note that
2443 transformations are inactive as long as no MIME-type is selected.</li>
2445 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2446 hopefully growing amount of pre-defined transformations. See below for information on
2447 how to build your own transformation.<br />
2449 There are global transformations and mimetype-bound transformations. Global transformations
2450 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2451 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2452 transformations which operate on the main mimetype (like 'image'), which will most likely
2453 take the subtype into regard, and those who only operate on a
2454 specific subtype (like 'image/jpeg').<br />
2456 You can use transformations on mimetypes for which the function was not defined for. There
2457 is no security check for you selected the right transformation, so take care of what the
2458 output will be like.</li>
2460 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2461 transform-function specific options here. Usually the transforms can operate with default
2462 options, but it is generally a good idea to look up the overview to see which options are
2463 necessary.<br />
2465 Much like the ENUM/SET-Fields, you have to split up several options using the format
2466 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2467 parsed as an array, leaving the first value the first element in the array, and so
2468 forth.<br />
2470 If you want to specify a MIME character set you can define it in the transformation_options.
2471 You have to put that outside of the pre-defined options of the specific mime-transform,
2472 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2473 for which you can specify 2 options and you want to append a character set, enter "'first
2474 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2475 the parameters: "'','','charset=us-ascii'".</li>
2476 </ul>
2478 <h3 id="transformationsfiles">3. File structure</h3>
2480 <p> All mimetypes and their transformations are defined through single files in
2481 the directory 'libraries/transformations/'.</p>
2483 <p> They are stored in files to ease up customization and easy adding of new
2484 transformations.</p>
2486 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2487 always work. It makes no sense to apply a transformation to a mimetype the
2488 transform-function doesn't know to handle.</p>
2490 <p> One can, however, use empty mime-types and global transformations which should work
2491 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2492 for, but pay attention to option usage as well as what the transformation does to your
2493 column.</p>
2495 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2496 any other transform function and provides some basic functions.</p>
2498 <p> There are 5 possible file names:</p>
2500 <ol><li>A mimetype+subtype transform:<br /><br />
2502 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2504 Please not that mimetype and subtype are separated via '_', which shall
2505 not be contained in their names. The transform function/filename may
2506 contain only characters which cause no problems in the file system as
2507 well as the PHP function naming convention.<br /><br />
2509 The transform function will the be called
2510 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2512 <b>Example:</b><br /><br />
2514 <tt>text_html__formatted.inc.php</tt><br />
2515 <tt>PMA_transform_text_html__formatted()</tt></li>
2517 <li>A mimetype (w/o subtype) transform:<br /><br />
2519 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2521 Please note that there are no single '_' characters.
2522 The transform function/filename may contain only characters which cause
2523 no problems in the file system as well as the PHP function naming
2524 convention.<br /><br />
2526 The transform function will the be called
2527 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2529 <b>Example:</b><br /><br />
2531 <tt>text__formatted.inc.php</tt><br />
2532 <tt>PMA_transform_text__formatted()</tt></li>
2534 <li>A mimetype+subtype without specific transform function<br /><br />
2536 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2538 Please note that there are no '__' characters in the filename. Do not
2539 use special characters in the filename causing problems with the file
2540 system.<br /><br />
2542 No transformation function is defined in the file itself.<br /><br />
2544 <b>Example:</b><br /><br />
2546 <tt>text_plain.inc.php</tt><br />
2547 (No function)</li>
2549 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2551 <tt>[mimetype].inc.php</tt><br /><br />
2553 Please note that there are no '_' characters in the filename. Do not use
2554 special characters in the filename causing problems with the file system.
2555 <br /><br />
2557 No transformation function is defined in the file itself.<br /><br />
2559 <b>Example:</b><br /><br />
2561 <tt>text.inc.php</tt><br />
2562 (No function)</li>
2564 <li>A global transform function with no specific mimetype<br /><br />
2566 <tt>global__[transform].inc.php</tt><br /><br />
2568 The transform function will the be called
2569 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2571 <b>Example:</b><br /><br />
2573 <tt>global__formatted</tt><br />
2574 <tt>PMA_transform_global__formatted()</tt></li>
2575 </ol>
2577 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2578 transform function.</p>
2580 <p> All filenames containing no '__' in themselves are not shown as valid transform
2581 functions in the dropdown.</p>
2583 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2584 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2585 without a transform function.</p>
2587 <p> To create a new transform function please see
2588 <tt>libraries/transformations/template_generator.sh</tt>.
2589 To create a new, empty mimetype please see
2590 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2592 <p> A transform function always gets passed three variables:</p>
2594 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2595 you want to transform.</li>
2596 <li><b>$options</b> - Contains any user-passed options to a transform function
2597 as an array.</li>
2598 <li><b>$meta</b> - Contains an object with information about your column.
2599 The data is drawn from the output of the
2600 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2601 function. This means, all object properties described on the
2602 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2603 available in this variable and can be used to transform a column accordingly
2604 to unsigned/zerofill/not_null/... properties.<br />
2605 The $meta-&gt;mimetype variable contains the original MIME-type of the
2606 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2607 </ol>
2609 <p> Additionally you should also provide additional function to provide
2610 information about the transformation to the user. This function should
2611 have same name as transformation function just with appended
2612 <code>_info</code> suffix. This function accepts no parameters and returns
2613 array with information about the transformation. Currently following keys
2614 can be used:
2615 </p>
2616 <dl>
2617 <dt><code>info</code></dt>
2618 <dd>Long description of the transformation.</dd>
2619 </dl>

2775 </h4>
2777 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2778 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2779 to take advantage of the new import features.</p>
2781 <p> The first things to check (or ask your host provider to check) are the
2782 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2783 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2784 All of these three settings limit the maximum size of data that can be
2785 submitted and handled by PHP. One user also said that post_max_size
2786 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2788 There exist several workarounds if your upload is too big or your
2789 hosting provider is unwilling to change the settings:</p>
2791 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2792 feature. This allows one to
2793 upload a file to the server via scp, ftp, or your favorite file transfer
2794 method. PhpMyAdmin is then able to import the files from the temporary
2795 directory. More information is available in the <a href="#config">Configuration
2796 section</a> of this document.</li>
2797 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2798 BigDump</a>) to split the files before uploading. We cannot support this
2799 or any third party applications, but are aware of users having success
2800 with it.</li>
2801 <li>If you have shell (command line) access, use MySQL to import the files
2802 directly. You can do this by issuing the &quot;source&quot; command from
2803 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>

2806 <h4 id="faq1_17">
2807 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2808 support?</a></h4>
2810 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2811 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2812 connect to your MySQL server using PHP's classic
2813 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2814 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2815 is available in php 5.0. The latter one should be used unless you have a
2816 good reason not to do so.<br />
2817 When compiling PHP, we strongly recommend that you manually link the MySQL
2818 extension of your choice to a MySQL client library of at least the same
2819 minor version since the one that is bundled with some PHP distributions is
2820 rather old and might cause problems <a href="#faq1_17a">
2821 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.<br /><br />
2822 MariaDB is also supported (versions 5.1 and 5.2 were tested).

2827 message, &quot;Client does not support authentication protocol requested

2830 <p> You tried to access MySQL with an old MySQL client library. The version of
2831 your MySQL client library can be checked in your phpinfo() output.
2832 In general, it should have at least the same minor version as your server
2833 - as mentioned in <a href="#faq1_17">
2834 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2836 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2837 changed the authentication hash and your PHP is trying to use the old method.
2838 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2839 with the proper client library to match your MySQL installation. Your
2840 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2861 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called

2863 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2864 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried

3077 problems with some operations, for example editing a table with many
3078 columns and no primary key or with textual primary key.
3079 </p>
3081 Suhosin configuration might lead to malfunction in some cases and it can
3082 not be fully avoided as phpMyAdmin is kind of application which needs to
3083 transfer big amounts of columns in single HTTP request, what is something
3084 what Suhosin tries to prevent. Generally all
3085 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3086 <code>suhosin.get.*</code> directives can have negative effect on
3087 phpMyAdmin usability. You can always find in your error logs which limit
3088 did cause dropping of variable, so you can diagnose the problem and adjust
3089 matching configuration variable.
3090 </p>
3092 The default values for most Suhosin configuration options will work in most

3182 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3184 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3185 In your <i>php.ini</i> you will find a line</p>
3187 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3189 <p> change it to</p>
3191 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3193 <p> Then restart apache and it will work.</p>
3195 <p> Here is a fix suggested by Brad Ummer:</p>
3197 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3198 To do this, telnet to your server and go to the MySQL bin directory. In
3199 this directory there should be a file named <i>mysqladmin</i>. Type
3200 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3201 info about your MySQL server, including the socket
3202 (<i>/tmp/mysql.sock</i>, for example).</li>
3203 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3204 phpMyAdmin, you need to complete the socket information in the
3205 <i>config.inc.php</i>.<br />
3206 For example:
3207 <a href="#cfg_Servers_socket" class="configrule">
3208 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
3209 <br /><br />
3211 Please also make sure that the permissions of this file allow to be readable
3212 by your webserver (i.e. '0755').</li>
3213 </ul>
3215 <p> Have also a look at the
3216 <a href="http://dev.mysql.com/doc/en/can-not-connect-to-server.html">
3217 corresponding section of the MySQL documentation</a>.</p>

3244 <p> When you are using a port on your localhost, which you redirect via
3245 port-forwarding to another host, MySQL is not resolving the localhost
3246 as expected.<br />
3247 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
3248 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3249 connection for speeding up things. And that doesn't work in this configuration
3250 with port forwarding.<br />

3256 <p> Themes are configured with
3257 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>,
3258 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
3259 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
3260 <br />
3261 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
3262 should not delete the directory &quot;original&quot; or its underlying
3263 structure, because this is the system theme used by phpMyAdmin.
3264 &quot;original&quot; contains all images and styles, for backwards
3265 compatibility and for all themes that would not include images or css-files.
3266 <br /><br />
3268 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
3269 is enabled, you can select your favorite theme on the main page. Your
3270 selected theme will be stored in a cookie.<br /><br /></p>
3272 <p> To create a theme:</p>
3274 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
3275 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
3276 (by default <tt>themes</tt>)</li>
3277 <li>copy the files and directories from &quot;original&quot; to
3278 &quot;your_theme_name&quot;</li>
3279 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
3280 <li>put your new images in &quot;your_theme_name/img&quot;</li>
3281 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
3282 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
3283 contain your chosen theme name, that will be visible in user interface</li>
3284 <li>make a new screenshot of your theme and save it under
3285 &quot;your_theme_name/screen.png&quot;</li>
3286 </ul>
3288 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3289 theme verbose name, theme generation and theme version. These versions and
3290 generations are enumerated from 1 and do not have any direct dependence on
3291 phpMyAdmin version. Themes within same generation should be backwards
3292 compatible - theme with version 2 should work in phpMyAdmin requiring
3293 version 1. Themes with different generation are incompatible.</p>
3295 <p> If you do not want to use your own symbols and buttons, remove the
3296 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
3297 use the default icons and buttons (from the system-theme &quot;original&quot;).

4104 <p>
4105 To use SQL Validator, you need PHP with
4106 <abbr title="Extensible Markup Language">XML</abbr>,
4107 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
4108 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
4109 In addition you need a <abbr title="Simple Object Access
4110 Protocol">SOAP</abbr> support, either as a PHP extension or as a PEAR SOAP
4111 module.
4112 </p>
4115 To install <abbr title="PHP Extension and Application
4116 Repository">PEAR</abbr> <abbr title="Simple Object Access
4117 Protocol">SOAP</abbr> module, run <tt>"pear install Net_Socket Net_URL

4119 title="PHP Extension and Application Repository">PEAR</abbr> modules for
4120 usage.
4121 </p>
4124 If you use the Validator, you should be aware that any
4125 <abbr title="structured query language">SQL</abbr> statement you
4126 submit will be stored anonymously (database/table/column names,
4127 strings, numbers replaced with generic values). The Mimer

4138 <p> The right way to do this, is to create the column without any indexes,
4139 then display the table structure and use the &quot;Create an index&quot;
4140 dialog. On this page, you will be able to choose your BLOB column, and
4141 set a size to the index, which is the condition to create an index on
4142 a BLOB column.</p>

4145 <a href="#faq6_16">6.16 How can I simply move in page with plenty

4148 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4149 with many editing fields (table structure changes, row editing, etc.).
4150 You can also have a look at the directive
4151 <a href="#DefaultPropDisplay" class="configrule">$cfg['DefaultPropDisplay']</a>

4155 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
4156 WTF is this feature then useful for?</a></h4>
4158 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4159 on them. Otherwise you could just put a comment on the column. Because entering
4160 your own mimetype will cause serious syntax checking issues and validation,
4161 this introduces a high-risk false-user-input situation. Instead you have to
4162 initialize mimetypes using functions or empty mimetype definitions.<br />
4163 Plus, you have a whole overview of available mimetypes. Who knows all those
4164 mimetypes by heart so he/she can enter it at will?</p>
4166 <h4 id="faqbookmark">
4167 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
4168 can't I see any bookmarks below the query box? What is this variable for?
4169 </a></h4>
4171 <p> Any query you have executed can be stored as a bookmark on the page where the
4172 results are displayed. You will find a button labeled 'Bookmark this query'
4173 just at the end of the page.<br />
4174 As soon as you have stored a bookmark, it is related to the database you run
4175 the query on. You can now access a bookmark dropdown on each page, the query
4176 box appears on for that database.<br /><br />
4178 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4179 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
4180 which is put into the <i>value</i> input box on the query box page will
4181 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
4182 aware of that you HAVE to create a valid query, otherwise your query won't be
4183 even able to be stored in the database.<br />
4184 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
4185 for your query will remain the way it is, but will be stripped of the /**/
4186 chars. So you can use:<br /><br />
4188 <code>/*, [VARIABLE] AS myname */</code><br /><br />
4190 which will be expanded to<br /><br />
4192 <code>, VARIABLE as myname</code><br /><br />
4194 in your query, where VARIABLE is the string you entered in the input box. If
4195 an empty string is provided, no replacements are made.<br /><br />
4197 A more complex example. Say you have stored this query:<br /><br />
4198 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
4199 <br /><br />
4201 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
4202 the full query will be:<br /><br />
4204 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
4205 <br /><br />
4207 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
4208 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
4209 spaces inserted there
4210 will be later also inserted as spaces in your query and may lead to unexpected
4211 results especially when
4212 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
4213 Your initial query which is going to be stored as a bookmark has to yield at
4214 least one result row so
4215 you can store the bookmark. You may have that to work around using well
4216 positioned &quot;/**/&quot; comments.</p>

4253 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
4254 6.6</a> for an example. Then, if there are 100 values or less in the

4256 You will see two lists of values, the first list containing the key
4257 and the display column, the second list containing the display column
4258 and the key. The reason for this is to be able to type the first
4259 letter of either the key or the display column.<br /><br />
4261 For 100 values or more, a distinct window will appear, to browse foreign
4262 key values and choose one. To change the default limit of 100, see

4301 <ul>
4302 <li>PBMS BLOB Streaming Daemon for MySQL (0.5.15 or later)</li>
4303 <li>Streaming enabled PBXT Storage engine for MySQL (1.0.11-6 or

4307 </ul>
4309 <p>Here are details about configuration and operation:</p>
4311 <ol>
4312 <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of &quot;localhost&quot;.</li>
4313 <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>
4314 <li>When you insert or update a row in this table, put a checkmark on the &quot;Upload to BLOB repository&quot; optional choice; otherwise, the upload will be done directly in your LONGBLOB column instead of the repository.</li>
4315 <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example &quot;View image&quot;. A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time.</li>

4357 By clicking on the button 'toggle scratchboard' on the page
4358 where you edit x/y coordinates of those elements you can activate a
4359 scratchboard where all your elements are placed. By clicking on an
4360 element, you can move them around in the pre-defined area and the x/y
4361 coordinates will get updated dynamically. Likewise, when entering a
4362 new position directly into the input field, the new position in the
4363 scratchboard changes after your cursor leaves the input field.
4364 </p>
4366 You have to click on the 'OK'-button below the tables to save the new
4367 positions. If you want to place a new element, first add it to the
4368 table of elements and then you can drag the new element around.

4406 translate online at our <a href="http://l10n.cihar.com/">translation
4407 server</a> where you can also get the latest po files and merge them
4408 with your translations. For creating a new translation simply use
4409 <code>po/phpmyadmin.pot</code> and generate
4410 <code>po/LANG_CODE.po</code> for your language (you can use
4411 <code>msginit -i po/phpmyadmin.pot -l LANG_CODE --no-translator -o po/LANG_CODE.po</code>
4412 to do this) or ask on the mailing list to add the translation to the web
4413 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Gettext_for_translators">our wiki</a>.
4414 </p>
4416 Please note that we try not to use HTML entities like &amp;eacute; in
4417 the translations, since we define the right character set in the file.
4418 With HTML entities, the text on JavaScript messages would not
4419 display correctly.
4420 However there are some entities that need to be there: quotes,
4421 non-breakable spaces, ampersands, less than, greater than.
4422 </p>
4424 You can then put your translations, as a zip file to avoid losing special

4514 It allows you to connect to local as well as remote servers. This requires you to enter
4515 server host name, username, password, port and the name of the database. Therefore you can
4516 now synchronize your databases placed on the same server or some remote server.
4517 </p>
4520 This feature is helpful for developers who need to replicate their
4521 database&#8217;s structure as well as data. Moreover, this feature not only
4522 helps replication but also facilitates the user to keep his/her database
4523 in sync with another database. Other than the full database, certain
4524 tables of the databases can also be synchronized.
4525 </p>
4528 You need to fill in the host name of the server, the username and
4529 password of an user account already there in MySQL. Port is by default
4530 populated with 3306 (MySQL default port). Then the name of the database
4531 should be mentioned at the end. All the information other than the port
4532 needs to be filled explicitly for the source as well as target servers.
4533 </p>
4536 After successfully passing through the authentication phase, the source and
4537 target database table names will be displayed. It will be a tabular
4538 representation.
4539 </p>
4542 On the left, are listed the source database table names. Some of the
4543 names have a <code>+</code> plus sign preceding them. This shows that these tables
4544 are only present in source database and they need to be added to the
4545 target database in order to synchronize the target database. The tables
4546 whose names are not preceded by a <code>+</code> sign are already present in the
4547 target database.
4548 </p>
4551 On the right, are listed the target database table names. There are few
4552 table names that have <code>(not present)</code> appended after their names. This
4553 means that these tables are to be created in target database in order to
4554 synchronize target database with source database. Some table names
4555 have a <code>-</code> minus sign preceding them. This shows that these tables are
4556 only present in target database and they will remain unchanged in the
4557 target database. The column in the middle shows the difference between
4558 the source and target corresponding tables.
4559 </p>
4562 The difference is depicted by the red and green buttons with <tt>S</tt> and <tt>D</tt>
4563 letters, indicating that either Structure or Data are not up to date. By
4564 clicking on them, they will turn grey, what means that they will be synchronized.
4565 </p>
4567 <!-- DEVELOPERS -->
4568 <h2 id="developers">Developers Information</h2>
4570 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
4571 great features have been written by other people and you too can help to
4572 make phpMyAdmin a useful tool.</p>
4574 <p> If you're planning to contribute source, please read the following
4575 information:</p>
4577 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
4578 <i>libraries/common.lib.php</i> (common functions) and
4579 <i>config.inc.php</i>.<br />
4580 Only configuration data should go in <i>config.inc.php</i>. Please keep
4581 it free from other code.<br />
4582 Commonly used functions should be added to
4583 <i>libraries/common.lib.php</i> and more specific ones may be added
4584 within a library stored into the <i>libraries</i> sub-directory.</li>
4585 <li>Obviously, you're free to use whatever coding style you want. But
4586 please try to keep your code as simple as possible: beginners are
4587 using phpMyAdmin as an example application.<br />
4588 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4589 compliant on one hand, they fit the
4590 <a href="http://pear.php.net/">
4591 <abbr title="PHP Extension and Application Repository">PEAR</abbr>
4592 coding standards</a>
4593 on the other hand. Please pay attention to this.</li>
4594 <li>Please enable showing PHP errors and warnings by the
4595 <code><a href="#cfg_Error_Handler_display">$cfg['Error_Handler']['display']</a></code>
4596 configuration directive.</li>
4597 <li>Please try to keep up the file-naming conventions. Table-related stuff
4598 goes to <i>tbl_*.php</i>, db-related code to <i>db_*.php</i>,
4599 server-related tools to <i>server_*.php</i> and so on.</li>
4600 <li>Please use gettext wrappers around all messages
4601 (<code>__('Some text')</code> or <code>_ngettext()</code> function).
4602 To translate them, you need to call <code>scripts/update-po</code>
4603 script. To use translated messages, call
4604 <code>scripts/generate-mo</code>, which generates binary files read by
4605 Gettext.</li>
4606 <li>If you want to be really helpful, write an entry for the ChangeLog.</li>
4607 <li id="developersdbg">
4608 The DBG extension (<a href="http://dd.cron.ru/dbg/">PHP
4609 Debugger DBG</a>) is now supported by phpMyAdmin for developers to
4610 better debug and profile their code.<br />
4611 Please see the
4612 <a href="#cfg_DBG" class="configrule">$cfg['DBG']*</a> configuration
4613 options for more information.<br />
4614 This is in memoriam of the Space Shuttle Columbia (STS-107) which was
4615 lost during its re-entry into Earth's atmosphere and in memory of the
4616 brave men and women who gave their lives for the people of Earth.</li>

4943 <h3>Original Credits of Version 2.1.0</h3>
4946 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4947 to create a web-based interface to MySQL using PHP3. Although I have not
4948 used any of his source-code, there are some concepts I've borrowed from
4949 him. phpMyAdmin was created because Peter told me he wasn't going to
4950 further develop his (great) tool.
4951 </p>
4953 Thanks go to
4954 </p>
4955 <ul>
4956 <li>Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4957 code for the check when dropping a table or database. He also suggested
4958 that you should be able to specify the primary key on tbl_create.php3. To
4959 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4960 well as a bug-report. Plus many smaller improvements.
4961 </li>
4962 <li>Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4963 were introduced in 1.3.0 (including quite significant ones like the
4964 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4965 bug-fixes and help.
4966 </li>
4967 <li>Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4968 language-independent by outsourcing the strings to a separate file. He
4969 also contributed the French translation.
4970 </li>
4971 <li>Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4972 tbl_select.php3, a feature to display only some columns from a table.
4973 </li>
4974 <li>Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4975 functions in tbl_change.php3. He also added the
4976 &quot;Query by Example&quot; feature in 2.0.
4977 </li>
4978 <li>Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4979 servers and is a regular contributor for bug-fixes.
4980 </li>
4981 <li>Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4982 features for 2.0.6.
4983 </li>
4984 </ul>
4986 The following people have contributed minor changes, enhancements, bugfixes
4987 or support for a new language:
