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

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

171 </ol>
173 <p class="important">
174 phpMyAdmin does not apply any special security methods to the MySQL database
175 server. It is still the system administrator's job to grant permissions on
176 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
177 be used for this.
178 </p>
180 <p class="important">
181 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
182 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
183 <abbr title="operating system">OS</abbr> version before
184 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
185 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
186 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
187 before uploading them to your server, as PHP seems not to like
188 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
189 (&quot;<tt>\r</tt>&quot;).</p>
191 <h3 id="quick_install">Quick Install</h3>
192 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
193 Downloads page. Some kits contain only the English messages,
194 others contain all languages in UTF-8 format (this should be fine
195 in most situations), others contain all
196 languages and all character sets. We'll assume you chose a kit whose
197 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
198 </li>
199 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
200 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
201 document root. If you don't have direct access to your document root,
202 put the files in a directory on your local machine, and, after step 4,
203 transfer the directory on your web server using, for example, ftp.</li>
204 <li>Ensure that all the scripts have the appropriate owner (if PHP is
205 running in safe mode, having some scripts with an owner different
206 from the owner of other scripts will be a
207 problem). See <a href="#faq4_2">
208 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
209 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
210 1.26</a> for suggestions.</li>
211 <li>Now you must configure your installation. There are two methods that
212 can be used. Traditionally, users have hand-edited a copy of
213 <tt>config.inc.php</tt>, but now a wizard-style setup script is
214 provided for those who prefer a graphical installation. Creating a
215 <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
216 <ul><li>To manually create the file, simply use your text editor to
217 create the file <tt>config.inc.php</tt> (you can copy
218 <tt>config.sample.inc.php</tt> to get minimal configuration
219 file) in the main (top-level) phpMyAdmin directory (the one
220 that contains <tt>index.php</tt>). phpMyAdmin first loads
221 <tt>libraries/config.default.php</tt> and then overrides those
222 values with anything found in <tt>config.inc.php</tt>. If the
223 default value is okay for a particular setting, there is no
224 need to include it in <tt>config.inc.php</tt>. You'll need a
225 few directives to get going, a simple configuration may look
226 like this:
227 <pre>
228 &lt;?php
229 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
231 $i=0;
232 $i++;
233 $cfg['Servers'][$i]['auth_type'] = 'cookie';
234 ?&gt;
235 </pre>
236 Or, if you prefer to not be prompted every time you log in:
237 <pre>
238 &lt;?php
240 $i=0;
241 $i++;
242 $cfg['Servers'][$i]['user'] = 'root';
243 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
244 $cfg['Servers'][$i]['auth_type'] = 'config';
245 ?&gt;
246 </pre>
247 For a full explanation of possible configuration values, see the
248 <a href="#config">Configuration Section</a> of this document.</li>
249 <li id="setup_script">Instead of manually editing
250 <tt>config.inc.php</tt>, you can use the
251 <a href="setup/">Setup Script</a>. First you must
252 manually create a folder <tt>config</tt> in the phpMyAdmin
253 directory. This is a security measure. On a Linux/Unix system you
254 can use the following commands:
255 <pre>
256 cd phpMyAdmin
257 mkdir config # create directory for saving
258 chmod o+rw config # give it world writable permissions
259 </pre>
260 And to edit an existing configuration, copy it over first:
261 <pre>
262 cp config.inc.php config/ # copy current configuration for editing
263 chmod o+w config/config.inc.php # give it world writable permissions
264 </pre>
265 On other platforms, simply create the folder and ensure that your
266 web server has read and write access to it. <a href="#faq1_26">FAQ
267 1.26</a> can help with this.<br /><br />
269 Next, open <tt><a href="setup/">setup/</a>
270 </tt>in your browser. Note that <strong>changes are not saved to
271 disk until explicitly choose <tt>Save</tt></strong> from the
272 <i>Configuration</i> area of the screen. Normally the script saves
273 the new config.inc.php to the <tt>config/</tt> directory, but if
274 the webserver does not have the proper permissions you may see the
275 error "Cannot load or save configuration." Ensure that the <tt>
276 config/</tt> directory exists and has the proper permissions -
277 or use the <tt>Download</tt> link to save the config file locally
278 and upload (via FTP or some similar means) to the proper location.<br /><br />
280 Once the file has been saved, it must be moved out of the <tt>
281 config/</tt> directory and the permissions must be reset, again
282 as a security measure:
283 <pre>
284 mv config/config.inc.php . # move file to current directory
285 chmod o-rw config.inc.php # remove world read and write permissions
286 rm -rf config # remove not needed directory
287 </pre>
288 Now the file is ready to be used. You can choose to review or edit
289 the file with your favorite editor, if you prefer to set some
290 advanced options which the setup script does not provide.</li></ul></li>
291 <li>If you are using the
292 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
293 protect the phpMyAdmin installation directory because using
294 config does not require a user to
295 enter a password to access the phpMyAdmin installation. Use of an alternate
296 authentication method is recommended, for example with
297 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
298 <tt>auth_type</tt> cookie or http. See the
299 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
300 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
301 information, especially <a href="#faq4_4">
302 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
303 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
304 in your browser. phpMyAdmin should now display a welcome screen
305 and your databases, or a login dialog if using
306 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
307 authentication mode.</li>
308 <li>You should deny access to the <tt>./libraries</tt> and
309 <tt>./setup/lib</tt> subfolders in your webserver configuration. For
310 Apache you can use supplied .htaccess file in that folder, for other
311 webservers, you should configure this yourself. Such configuration
312 prevents from possible path exposure and cross side scripting
313 vulnerabilities that might happen to be found in that code.</li>
314 <li>
315 It is generally good idea to protect public phpMyAdmin installation
316 against access by robots as they usually can not do anything good
317 there. You can do this using <code>robots.txt</code> file in root of
318 your webserver or limit access by web server configuration. You can
319 find example <code>.htaccess</code> file which can help you achieve
320 this in <code>contrib</code> directory in phpMyAdmin.
321 </li>
322 </ol>
324 <h3 id="linked-tables">phpMyAdmin configuration storage</h3>
326 <p> For a whole set of new features (bookmarks, comments,
327 <abbr title="structured query language">SQL</abbr>-history,
328 tracking mechanism,
329 <abbr title="Portable Document Format">PDF</abbr>-generation, column contents
330 transformation, etc.) you need to create a set of special tables. Those
331 tables can be located in your own database, or in a central database for a
332 multi-user installation (this database would then be accessed by the
333 controluser, so no other user should have rights to it).</p>
335 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
336 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
337 special attention to <a href="#faq1_23">
338 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
340 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
341 or newer, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>
342 and then create new tables by importing <i>./scripts/create_tables.sql</i>.</p>
344 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
345 that you may need special (administrator) privileges to create the database
346 and tables, and that the script may need some tuning, depending on the
347 database name.</p>
349 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
350 should specify the table names in your <i>./config.inc.php</i> file. The
351 directives used for that can be found in the <a href="#config">Configuration
352 section</a>. You will also need to have a controluser with the proper rights
353 to those tables (see section <a href="#authentication_modes">Using
354 authentication modes</a> below).</p>
356 <h3 id="upgrading">Upgrading from an older version</h3>
358 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
359 unpacked one. Configuration files from old versions may
360 require some tweaking as some options have been changed or removed; in
361 particular, the definition of <tt>$cfg['AttributeTypes']</tt> has changed
362 so you better remove it from your file and just use the default one.
363 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
364 statement that you might find near the end of your configuration file.</p>
366 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
367 over <tt>config.inc.php</tt> because the default configuration file
368 is version-specific.</p>
370 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
371 version 5.x or newer and if you use the phpMyAdmin configuration storage,
372 you should run the SQL script found in
373 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
375 <h3 id="authentication_modes">Using authentication modes</h3>
377 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
378 authentication modes are recommended in a <b>multi-user environment</b>
379 where you want to give users access to their own database and don't want
380 them to play around with others.<br />
381 Nevertheless be aware that MS Internet Explorer seems to be really buggy
382 about cookies, at least till version 6.<br />
383 Even in a <b>single-user environment</b>, you might prefer to use
384 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
385 that your user/password pair are not in clear in the configuration file.
386 </li>
388 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
389 authentication modes are more secure: the MySQL login information does
390 not need to be set in the phpMyAdmin configuration file (except possibly
391 for the <a href="#controluser">controluser</a>).<br />
392 However, keep in mind that the password travels in plain text, unless
393 you are using the HTTPS protocol.<br />
394 In cookie mode, the password is stored, encrypted with the blowfish
395 algorithm, in a temporary cookie.</li>
397 <li id="pmausr">Note: this section is only applicable if
398 your MySQL server is running with <tt>--skip-show-database</tt>.<br /><br />
400 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
401 modes, phpMyAdmin needs a controluser that has <b>only</b> the
402 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
403 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
404 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
405 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
406 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
407 file under the
408 <tt><a href="#cfg_Servers_controluser" class="configrule">
409 $cfg['Servers'][$i]['controluser']</a></tt> and
410 <tt><a href="#cfg_Servers_controlpass" class="configrule">
411 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
412 The following example assumes you want to use <tt>pma</tt> as the
413 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
414 only an example: use something else in your file!</b> Input these
415 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
416 client.<br />
417 Of course you have to replace <tt>localhost</tt> with the webserver's host
418 if it's not the same as the MySQL server's one.
420 <pre>
421 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
422 GRANT SELECT (
423 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
424 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
425 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
426 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
427 Execute_priv, Repl_slave_priv, Repl_client_priv
428 ) ON mysql.user TO 'pma'@'localhost';
429 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
430 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
431 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
432 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
434 If you want to use the many new relation and bookmark features:
436 <pre>
437 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
438 </pre>
440 (this of course requires that your <a href="#linked-tables">phpMyAdmin
441 configuration storage</a> be set up).
442 <br /></li>
444 <li>Then each of the <i>true</i> users should be granted a set of privileges
445 on a set of particular databases. Normally you shouldn't give global
446 privileges to an ordinary user, unless you understand the impact of those
447 privileges (for example, you are creating a superuser).<br />
448 For example, to grant the user <i>real_user</i> with all privileges on
449 the database <i>user_base</i>:<br />
451 <pre>
452 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';

457 With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
458 authentication mode, you don't need to fill the user/password fields
459 inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
460 array.</li>
461 </ul>
463 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>
465 <ul><li>Uses <abbr title="HyperText Transfer Protocol">HTTP</abbr> Basic authentication
466 method and allows you to log in as any valid MySQL user.</li>
467 <li>Is supported with most PHP configurations. For

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

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

590 Note also that the <abbr title="Uniform Resource Locator">URL</abbr> on
591 some web servers are case&#8211;sensitive.
592 Don&#8217;t forget the trailing slash at the end.<br /><br />
594 Starting with version 2.3.0, it is advisable to try leaving this
595 blank. In most cases phpMyAdmin automatically detects the proper
596 setting. Users of port forwarding will need to set PmaAbsoluteUri (<a
597 href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1340187&amp;group_id=23067&amp;atid=377409">more info</a>).
598 A good test is to browse a table, edit a row and save it. There should
599 be an error message if phpMyAdmin is having trouble auto&#8211;detecting
600 the correct value. If you get an error that this must be set or if
601 the autodetect code fails to detect your path, please post a bug

640 Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
641 makes a bit weaker security as this generated secret is stored in
642 session and furthermore it makes impossible to recall user name from
643 cookie.</dd>
645 <dt id="cfg_Servers">$cfg['Servers'] array</dt>
646 <dd>Since version 1.4.2, phpMyAdmin supports the administration of multiple

816 of these characters, escape them (I.E. use <tt>'my\_db'</tt> and not
817 <tt>'my_db'</tt>).<br />
818 This setting is an efficient way to lower the server load since the

830 As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the

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

896 which column is a key in another table (a foreign key). phpMyAdmin
897 currently uses this to
898 <ul><li>make clickable, when you browse the master table, the data values
899 that point to the foreign table;</li>
900 <li>display in an optional tool-tip the &quot;display column&quot;

914 <li>enable you to get a <abbr title="Portable Document Format">PDF</abbr>
915 schema of your database (also uses the table_coords table).</li>
916 </ul>
918 The keys can be numeric or character.<br /><br />
920 To allow the usage of this functionality:
922 <ul><li>set up <a href="#pmadb">pmadb</a> and the phpMyAdmin
923 configuration storage</li>
924 <li>put the relation table name in
925 <tt>$cfg['Servers'][$i]['relation']</tt></li>
926 <li>now as normal user open phpMyAdmin and for each one of your
927 tables where you want to use this feature, click
928 &quot;Structure/Relation view/&quot; and choose foreign
929 columns.
930 </li>
931 </ul>
933 Please note that in the current version, <tt>master_db</tt>
934 must be the same as <tt>foreign_db</tt>. Those columns have been put in
935 future development of the cross-db relations.

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

989 <br /><br />
991 Starting with release 2.5.0, comments are consequently used on the table
992 property pages and table browse view, showing up as tool-tips above the
993 column name (properties page) or embedded within the header of table in
994 browse view. They can also be shown in a table dump. Please see the
995 relevant configuration directives later on.<br /><br />
997 Also new in release 2.5.0 is a MIME-transformation system which is also
998 based on the following table structure. See <a href="#transformations">
999 Transformations</a> for further information. To use the
1000 MIME-transformation system, your column_info table has to have the three
1001 new columns 'mimetype', 'transformation', 'transformation_options'.

1035 Using

1056 Since release 3.3.x a tracking mechanism is available.
1057 It helps you to track every <abbr title="structured query language">SQL</abbr> command which
1058 is executed by phpMyAdmin. The mechanism supports logging of data manipulation
1059 and data definition statements. After enabling it you can create versions of tables.
1060 <br/><br/>
1061 The creation of a version has two effects:
1063 <ul>
1064 <li>phpMyAdmin saves a snapshot of the table, including structure and indexes.</li>
1065 <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
1066 </ul>
1068 Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
1069 For the report you can use filters, for example you can get a list of statements within a date range.
1070 When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
1071 In addition you can export the (filtered) report to a file or to a temporary database.

1998 files, see <a href="#faq1_11"><abbr title="Frequently Asked Questions">FAQ</abbr>
1999 1.11</a>.
2000 <br /><br />
2002 If the directory where phpMyAdmin is installed is subject to an
2003 <tt>open_basedir</tt> restriction, you need to create a
2004 temporary directory in some directory accessible by the web
2005 server. However for security reasons, this directory should be outside
2006 the tree published by webserver. If you cannot avoid having this
2007 directory published by webserver, place at least an empty
2008 <tt>index.html</tt> file there, so that directory listing is not
2009 possible.
2010 <br /><br />
2012 This directory should have as strict permissions as possible as the only
2013 user required to access this directory is the one who runs the
2014 webserver. If you have root privileges, simply make this user owner of
2015 this directory and make it accessible only by it:
2016 <br /><br />
2018 <pre>
2019 chown www-data:www-data tmp
2020 chmod 700 tmp
2021 </pre>
2023 If you cannot change owner of the directory, you can achieve a similar
2024 setup using <abbr title="Access Control List">ACL</abbr>:
2026 <pre>
2027 chmod 700 tmp
2028 setfacl -m "g:www-data:rwx" tmp
2029 setfacl -d -m "g:www-data:rwx" tmp
2030 </pre>
2032 If neither of above works for you, you can still make the directory
2033 <code>chmod 777</code>, but it might impose risk of other users on
2034 system reading and writing data in this directory.

2074 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
2075 or icon is always displayed on the left panel. If JavaScript is enabled in
2076 your browser, a click on this opens a distinct query window, which is
2077 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
2078 changes to display a query box.<br /><br />
2080 The size of this query window can be customized with
2081 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowHeight']</tt>
2082 - both integers for the size in pixels. Note that normally, those
2083 parameters will be modified in <tt>layout.inc.php</tt> for the
2084 theme you are using.<br /><br />
2086 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
2087 from the results page (in the &quot;Showing Rows&quot; section)
2088 opens the query window and puts the current query
2089 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
2090 query in the right panel's query box.
2091 <br /><br />
2092 The usage of the JavaScript query window is recommended if you have a
2093 JavaScript enabled browser. Basic functions are used to exchange quite
2094 a few variables, so most 4th generation browsers should be capable to
2095 use that feature. It currently is only tested with Internet Explorer 6
2096 and Mozilla 1.x.
2097 <br /><br />
2098 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
2099 to a table, which has to be created by you (see <a
2100 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
2101 all your queries will be appended to the form, but only as long as
2102 your window is opened they remain saved.
2103 <br /><br />
2104 When using the JavaScript based query window, it will always get
2105 updated when you click on a new table/db to browse and will focus if
2106 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
2107 the query window by checking the box "Do not overwrite this query from
2108 outside the window" below the query textarea. Then you can browse
2109 tables/databases in the background without losing the contents of the
2110 textarea, so this is especially useful when composing a query with
2111 tables you first have to look in. The checkbox will get automatically
2112 checked whenever you change the contents of the textarea. Please
2113 uncheck the button whenever you definitely want the query window to
2114 get updated even though you have made alterations.
2115 <br /><br />
2116 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
2117 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
2118 <br /><br />
2119 The query window also has a custom tabbed look to group the features.
2120 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
2121 default tab to be used when opening the query window. It can be set to
2122 either 'sql', 'files', 'history' or 'full'.</dd>

2324 <h2 id="transformations">Transformations</h2>
2326 <ol><li><a href="#transformationsintro">Introduction</a></li>
2327 <li><a href="#transformationshowto">Usage</a></li>
2328 <li><a href="#transformationsfiles">File structure</a></li>
2329 </ol>
2331 <h3 id="transformationsintro">1. Introduction</h3>
2333 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2334 and the proper directives. Please see the <a href="#config">Configuration
2335 section</a> on how to do so.</p>
2337 <p> You can apply different transformations to the contents of each column. The
2338 transformation will take the content of each column and transform it with
2339 certain rules defined in the selected transformation.</p>
2341 <p> Say you have a column 'filename' which contains a filename. Normally you would
2342 see in phpMyAdmin only this filename. Using transformations you can transform
2343 that filename into a HTML link, so you can click inside of the phpMyAdmin
2344 structure on the column's link and will see the file displayed in a new browser
2345 window. Using transformation options you can also specify strings to
2346 append/prepend to a string or the format you want the output stored in.</p>
2348 <p> For a general overview of all available transformations and their options,
2349 you can consult your
2350 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2351 installation.</p>
2353 <p> For a tutorial on how to effectively use transformations, see our
2354 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2355 the official phpMyAdmin homepage.</p>
2357 <h3 id="transformationshowto">2. Usage</h3>
2359 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2360 clicking on the 'Structure' link for a table). There click on
2361 &quot;Change&quot; (or change icon) and there you will see three new
2362 fields at
2363 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2364 'Transformation options'.</p>
2366 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2367 that corresponds to the column's contents. Please note that
2368 transformations are inactive as long as no MIME-type is selected.</li>
2370 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2371 hopefully growing amount of pre-defined transformations. See below for information on
2372 how to build your own transformation.<br />
2374 There are global transformations and mimetype-bound transformations. Global transformations
2375 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2376 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2377 transformations which operate on the main mimetype (like 'image'), which will most likely
2378 take the subtype into regard, and those who only operate on a
2379 specific subtype (like 'image/jpeg').<br />
2381 You can use transformations on mimetypes for which the function was not defined for. There
2382 is no security check for you selected the right transformation, so take care of what the
2383 output will be like.</li>
2385 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2386 transform-function specific options here. Usually the transforms can operate with default
2387 options, but it is generally a good idea to look up the overview to see which options are
2388 necessary.<br />
2390 Much like the ENUM/SET-Fields, you have to split up several options using the format
2391 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2392 parsed as an array, leaving the first value the first element in the array, and so
2393 forth.<br />
2395 If you want to specify a MIME character set you can define it in the transformation_options.
2396 You have to put that outside of the pre-defined options of the specific mime-transform,
2397 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2398 for which you can specify 2 options and you want to append a character set, enter "'first
2399 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2400 the parameters: "'','','charset=us-ascii'".</li>
2401 </ul>
2403 <h3 id="transformationsfiles">3. File structure</h3>
2405 <p> All mimetypes and their transformations are defined through single files in
2406 the directory 'libraries/transformations/'.</p>
2408 <p> They are stored in files to ease up customization and easy adding of new
2409 transformations.</p>
2411 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2412 always work. It makes no sense to apply a transformation to a mimetype the
2413 transform-function doesn't know to handle.</p>
2415 <p> One can, however, use empty mime-types and global transformations which should work
2416 for many mimetypes. You can also use transforms on a different mimetype than what they where built
2417 for, but pay attention to option usage as well as what the transformation does to your
2418 column.</p>
2420 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2421 any other transform function and provides some basic functions.</p>
2423 <p> There are 5 possible file names:</p>
2425 <ol><li>A mimetype+subtype transform:<br /><br />
2427 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2429 Please not that mimetype and subtype are separated via '_', which shall
2430 not be contained in their names. The transform function/filename may
2431 contain only characters which cause no problems in the file system as
2432 well as the PHP function naming convention.<br /><br />
2434 The transform function will the be called
2435 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2437 <b>Example:</b><br /><br />
2439 <tt>text_html__formatted.inc.php</tt><br />
2440 <tt>PMA_transform_text_html__formatted()</tt></li>
2442 <li>A mimetype (w/o subtype) transform:<br /><br />
2444 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2446 Please note that there are no single '_' characters.
2447 The transform function/filename may contain only characters which cause
2448 no problems in the file system as well as the PHP function naming
2449 convention.<br /><br />
2451 The transform function will the be called
2452 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2454 <b>Example:</b><br /><br />
2456 <tt>text__formatted.inc.php</tt><br />
2457 <tt>PMA_transform_text__formatted()</tt></li>
2459 <li>A mimetype+subtype without specific transform function<br /><br />
2461 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2463 Please note that there are no '__' characters in the filename. Do not
2464 use special characters in the filename causing problems with the file
2465 system.<br /><br />
2467 No transformation function is defined in the file itself.<br /><br />
2469 <b>Example:</b><br /><br />
2471 <tt>text_plain.inc.php</tt><br />
2472 (No function)</li>
2474 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2476 <tt>[mimetype].inc.php</tt><br /><br />
2478 Please note that there are no '_' characters in the filename. Do not use
2479 special characters in the filename causing problems with the file system.
2480 <br /><br />
2482 No transformation function is defined in the file itself.<br /><br />
2484 <b>Example:</b><br /><br />
2486 <tt>text.inc.php</tt><br />
2487 (No function)</li>
2489 <li>A global transform function with no specific mimetype<br /><br />
2491 <tt>global__[transform].inc.php</tt><br /><br />
2493 The transform function will the be called
2494 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2496 <b>Example:</b><br /><br />
2498 <tt>global__formatted</tt><br />
2499 <tt>PMA_transform_global__formatted()</tt></li>
2500 </ol>
2502 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2503 transform function.</p>
2505 <p> All filenames containing no '__' in themselves are not shown as valid transform
2506 functions in the dropdown.</p>
2508 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2509 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2510 without a transform function.</p>
2512 <p> To create a new transform function please see
2513 <tt>libraries/transformations/template_generator.sh</tt>.
2514 To create a new, empty mimetype please see
2515 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2517 <p> A transform function always gets passed three variables:</p>
2519 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2520 you want to transform.</li>
2521 <li><b>$options</b> - Contains any user-passed options to a transform function
2522 as an array.</li>
2523 <li><b>$meta</b> - Contains an object with information about your column.
2524 The data is drawn from the output of the
2525 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2526 function. This means, all object properties described on the
2527 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2528 available in this variable and can be used to transform a column accordingly
2529 to unsigned/zerofill/not_null/... properties.<br />
2530 The $meta-&gt;mimetype variable contains the original MIME-type of the
2531 column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2532 </ol>
2534 <p> Additionally you should also provide additional function to provide
2535 information about the transformation to the user. This function should
2536 have same name as transformation function just with appended
2537 <code>_info</code> suffix. This function accepts no parameters and returns
2538 array with information about the transformation. Currently following keys
2539 can be used:
2540 </p>
2541 <dl>
2542 <dt><code>info</code></dt>
2543 <dd>Long description of the transformation.</dd>
2544 </dl>

2644 <li>give ownership to the Apache server's user.group:

2702 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these

2704 to take advantage of the new import features.</p>
2706 <p> The first things to check (or ask your host provider to check) are the
2707 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2708 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2709 All of these three settings limit the maximum size of data that can be
2710 submitted and handled by PHP. One user also said that post_max_size
2711 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2713 There exist several workarounds if your upload is too big or your
2714 hosting provider is unwilling to change the settings:</p>

2717 feature. This allows one to
2718 upload a file to the server via scp, ftp, or your favorite file transfer

2732 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2733 support?</a></h4>
2735 <p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
2736 older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can
2737 connect to your MySQL server using PHP's classic
2738 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2739 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2740 is available in php 5.0. The latter one should be used unless you have
2741 good reason not to do so.<br />
2742 When compiling php, we strongly recommend that you manually link the MySQL
2743 extension of your choice to a MySQL client library of at least the same
2744 minor version since the one that is bundled with some PHP distributions is
2745 rather old and might cause problems <a href="#faq1_17a">
2746 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.</p>

2753 <p> You tried to access MySQL with an old MySQL client library. The version of
2754 your MySQL client library can be checked in your phpinfo() output.
2755 In general, it should have at least the same minor version as your server
2756 - as mentioned in <a href="#faq1_17">
2757 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2759 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2760 changed the authentication hash and your PHP is trying to use the old method.
2761 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2762 with the proper client library to match your MySQL installation. Your
2763 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.
2764 More information (and several workarounds) are located in the

2784 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2785 &quot;MySQL extension&quot;. This extension may be part of the PHP
2786 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2787 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2788 to load the extension but failed.<br /><br />

3000 problems with some operations, for example editing a table with many
3001 columns and no primary key or with textual primary key.
3002 </p>
3004 Suhosin configuration might lead to malfunction in some cases and it can
3005 not be fully avoided as phpMyAdmin is kind of application which needs to
3006 transfer big amounts of columns in single HTTP request, what is something
3007 what Suhosin tries to prevent. Generally all
3008 <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
3009 <code>suhosin.get.*</code> directives can have negative effect on
3010 phpMyAdmin usability. You can always find in your error logs which limit
3011 did cause dropping of variable, so you can diagnose the problem and adjust
3012 matching configuration variable.
3013 </p>
3015 The default values for most Suhosin configuration options will work in most
3016 scenarios, however you might want to adjust at least following parameters:

3105 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
3107 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
3108 In your <i>php.ini</i> you will find a line</p>
3110 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
3112 <p> change it to</p>
3114 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
3116 <p> Then restart apache and it will work.</p>
3118 <p> Here is a fix suggested by Brad Ummer:</p>
3120 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
3121 To do this, telnet to your server and go to the MySQL bin directory. In
3122 this directory there should be a file named <i>mysqladmin</i>. Type
3123 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
3124 info about your MySQL server, including the socket
3125 (<i>/tmp/mysql.sock</i>, for example).</li>
3126 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
3127 phpMyAdmin, you need to complete the socket information in the
3128 <i>config.inc.php</i>.<br />
3129 For example:
3130 <a href="#cfg_Servers_socket" class="configrule">
3131 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
3132 <br /><br />
3134 Please also make sure that the permissions of this file allow to be readable
3135 by your webserver (i.e. '0755').</li>
3136 </ul>
3138 <p> Have also a look at the
3139 <a href="http://dev.mysql.com/doc/en/can-not-connect-to-server.html">

3167 <p> When you are using a port on your localhost, which you redirect via
3168 port-forwarding to another host, MySQL is not resolving the localhost
3169 as expected.<br />
3170 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
3171 MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
3172 connection for speeding up things. And that doesn't work in this configuration
3173 with port forwarding.<br />
3174 If you enter "127.0.0.1" as hostname, everything is right and MySQL uses the
3175 <abbr title="Transmission Control Protocol">TCP</abbr> connection.</p>
3177 <h4 id="faqthemes"><a href="#faqthemes">2.7 Using and creating themes</a></h4>
3179 <p> Themes are configured with
3180 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>,
3181 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
3182 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
3183 <br />
3184 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
3185 should not delete the directory &quot;original&quot; or its underlying
3186 structure, because this is the system theme used by phpMyAdmin.
3187 &quot;original&quot; contains all images and styles, for backwards
3188 compatibility and for all themes that would not include images or css-files.
3189 <br /><br />
3191 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
3192 is enabled, you can select your favorite theme on the main page. Your
3193 selected theme will be stored in a cookie.<br /><br /></p>
3195 <p> To create a theme:</p>
3197 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
3198 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
3199 (by default <tt>themes</tt>)</li>
3200 <li>copy the files and directories from &quot;original&quot; to
3201 &quot;your_theme_name&quot;</li>
3202 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
3203 <li>put your new images in &quot;your_theme_name/img&quot;</li>
3204 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
3205 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
3206 contain your chosen theme name, that will be visible in user interface</li>
3207 <li>make a new screenshot of your theme and save it under
3208 &quot;your_theme_name/screen.png&quot;</li>
3209 </ul>
3211 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3212 theme verbose name, theme generation and theme version. These versions and
3213 generations are enumerated from 1 and do not have any direct dependence on
3214 phpMyAdmin version. Themes within same generation should be backwards
3215 compatible - theme with version 2 should work in phpMyAdmin requiring
3216 version 1. Themes with different generation are incompatible.</p>
3218 <p> If you do not want to use your own symbols and buttons, remove the
3219 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
3220 use the default icons and buttons (from the system-theme &quot;original&quot;).

3243 </li>
3244 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value

3463 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

4058 it, but MySQL says &quot;BLOB column '...' used in key specification without
4059 a key length&quot;.</a></h4>
4061 <p> The right way to do this, is to create the column without any indexes,
4062 then display the table structure and use the &quot;Create an index&quot;
4063 dialog. On this page, you will be able to choose your BLOB column, and
4064 set a size to the index, which is the condition to create an index on

4071 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
4072 with many editing fields (table structure changes, row editing, etc.).
4073 You can also have a look at the directive

4078 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
4079 WTF is this feature then useful for?</a></h4>
4081 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
4082 on them. Otherwise you could just put a comment on the column. Because entering
4083 your own mimetype will cause serious syntax checking issues and validation,
4084 this introduces a high-risk false-user-input situation. Instead you have to
4085 initialize mimetypes using functions or empty mimetype definitions.<br />
4086 Plus, you have a whole overview of available mimetypes. Who knows all those
4087 mimetypes by heart so he/she can enter it at will?</p>

4090 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
4091 can't I see any bookmarks below the query box? What is this variable for?
4092 </a></h4>
4094 <p> Any query you have executed can be stored as a bookmark on the page where the
4095 results are displayed. You will find a button labeled 'Bookmark this query'
4096 just at the end of the page.<br />
4097 As soon as you have stored a bookmark, it is related to the database you run
4098 the query on. You can now access a bookmark dropdown on each page, the query
4099 box appears on for that database.<br /><br />
4101 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
4102 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
4103 which is put into the <i>value</i> input box on the query box page will
4104 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
4105 aware of that you HAVE to create a valid query, otherwise your query won't be
4106 even able to be stored in the database.<br />
4107 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
4108 for your query will remain the way it is, but will be stripped of the /**/
4109 chars. So you can use:<br /><br />
4111 <code>/*, [VARIABLE] AS myname */</code><br /><br />
4113 which will be expanded to<br /><br />
4115 <code>, VARIABLE as myname</code><br /><br />
4117 in your query, where VARIABLE is the string you entered in the input box. If
4118 an empty string is provided, no replacements are made.<br /><br />
4120 A more complex example. Say you have stored this query:<br /><br />
4121 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
4122 <br /><br />
4124 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
4125 the full query will be:<br /><br />
4127 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
4128 <br /><br />
4130 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query.<br />
4131 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
4132 spaces inserted there
4133 will be later also inserted as spaces in your query and may lead to unexpected
4134 results especially when
4135 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
4136 Your initial query which is going to be stored as a bookmark has to yield at
4137 least one result row so
4138 you can store the bookmark. You may have that to work around using well
4139 positioned &quot;/**/&quot; comments.</p>

4176 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
4177 6.6</a> for an example. Then, if there are 100 values or less in the

4179 You will see two lists of values, the first list containing the key
4180 and the display column, the second list containing the display column
4181 and the key. The reason for this is to be able to type the first
4182 letter of either the key or the display column.<br /><br />
4184 For 100 values or more, a distinct window will appear, to browse foreign

4223 <p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
4224 <ul>
4225 <li>PBMS BLOB Streaming Daemon for MySQL (0.5.15 or later)</li>
4226 <li>Streaming enabled PBXT Storage engine for MySQL (1.0.11-6 or

4230 </ul>
4232 <p>Here are details about configuration and operation:</p>
4234 <ol>
4235 <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>
4236 <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>
4237 <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>
4238 <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>

4280 By clicking on the button 'toggle scratchboard' on the page
4281 where you edit x/y coordinates of those elements you can activate a
4282 scratchboard where all your elements are placed. By clicking on an
4283 element, you can move them around in the pre-defined area and the x/y
4284 coordinates will get updated dynamically. Likewise, when entering a
4285 new position directly into the input field, the new position in the
4286 scratchboard changes after your cursor leaves the input field.
4287 </p>
4289 You have to click on the 'OK'-button below the tables to save the new
4290 positions. If you want to place a new element, first add it to the

4328 <p> Always use latest Git version of the po file to translate. You can optionally
4329 translate online at our <a href="http://l10n.cihar.com/">translation
4330 server</a> where you can also get the latest po files and merge them
4331 with your translations. For creating a new translation simply use
4332 <code>po/phpmyadmin.pot</code> and generate
4333 <code>po/LANG_CODE.po</code> for your language (you can use
4334 <code>msginit -i po/phpmyadmin.pot -l LANG_CODE --no-translator -o po/LANG_CODE.po</code>
4335 to do this) or ask on the mailing list to add the translation to the web
4336 interface. More details are available on <a href="http://wiki.phpmyadmin.net/pma/Devel:Gettext_for_translators">our wiki</a>.
4337 </p>
4339 Please note that we try not to use HTML entities like &amp;eacute; in
4340 the translations, since we define the right character set in the file.
4341 With HTML entities, the text on JavaScript messages would not
4342 display correctly.
4343 However there are some entities that need to be there: quotes,
4344 non-breakable spaces, ampersands, less than, greater than.
4345 </p>
4347 You can then put your translations, as a zip file to avoid losing special
4348 characters, on the sourceforge.net <a href="https://sourceforge.net/tracker/?group_id=23067&amp;atid=387645">translation tracker.</a>

4405 <p> If you use Apache web server, phpMyAdmin exports information about
4406 authentication to the Apache environment and it can be used in Apache logs.
4407 Currently there are two variables available:
4408 </p>
4409 <dl>
4410 <dt><code>userID</code></dt>
4411 <dd>User name of currently active user (he does not have to be logged
4412 in).</dd>
4413 <dt><code>userStatus</code></dt>
4414 <dd>Status of currently active user, one of <code>ok</code> (user is
4415 logged in), <code>mysql-denied</code> (MySQL denied user login),
4416 <code>allow-denied</code> (user denied by allow/deny rules),
4417 <code>root-denied</code> (root is denied in configuration),
4418 <code>empty-denied</code> (empty password is denied).</dd>
4419 </dl>
4421 <code>LogFormat</code> directive for Apache can look like following:
4422 </p>
4423 <pre>
4424 LogFormat "%h %l %u %t \"%r\" %>s %b \
4425 \"%{Referer}i\" \"%{User-Agent}i\" %{userID}n %{userStatus}n" pma_combined

4433 <h4 id="faq9_1">
4434 <a href="#faq9_1">9.1 How can I synchronize two databases/tables in phpMyAdmin?</a></h4>
4436 <p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
4437 It allows you to connect to local as well as remote servers. This requires you to enter
4438 server host name, username, password, port and the name of the database. Therefore you can
4439 now synchronize your databases placed on the same server or some remote server.
4440 </p>
4443 This feature is helpful for developers who need to replicate their
4444 database&#8217;s structure as well as data. Moreover, this feature not only
4445 helps replication but also facilitates the user to keep his/her database
4446 in sync with another database. Other than the full database, certain
4447 tables of the databases can also be synchronized.
4448 </p>
4451 You need to fill in the host name of the server, the username and
4452 password of an user account already there in MySQL. Port is by default
4453 populated with 3306 (MySQL default port). Then the name of the database
4454 should be mentioned at the end. All the information other than the port
4455 needs to be filled explicitly for the source as well as target servers.
4456 </p>
4459 After successfully passing through the authentication phase, the source and
4460 target database table names will be displayed. It will be a tabular
4461 representation.
4462 </p>
4465 On the left, are listed the source database table names. Some of the
4466 names have a <code>+</code> plus sign preceding them. This shows that these tables
4467 are only present in source database and they need to be added to the
4468 target database in order to synchronize the target database. The tables
4469 whose names are not preceded by a <code>+</code> sign are already present in the
4470 target database.
4471 </p>
4474 On the right, are listed the target database table names. There are few
4475 table names that have <code>(not present)</code> appended after their names. This
4476 means that these tables are to be created in target database in order to
4477 synchronize target database with source database. Some table names
4478 have a <code>-</code> minus sign preceding them. This shows that these tables are
4479 only present in target database and they will remain unchanged in the
4480 target database. The column in the middle shows the difference between
4481 the source and target corresponding tables.
4482 </p>
4485 The difference is depicted by the red and green buttons with <tt>S</tt> and <tt>D</tt>
4486 letters, indicating that either Structure or Data are not up to date. By
4487 clicking on them, they will turn grey, what means that they will be synchronized.

4860 <h3>Original Credits of Version 2.1.0</h3>
4863 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4864 to create a web-based interface to MySQL using PHP3. Although I have not
4865 used any of his source-code, there are some concepts I've borrowed from
4866 him. phpMyAdmin was created because Peter told me he wasn't going to
4867 further develop his (great) tool.
4868 </p>
4870 Thanks go to
4871 </p>
4872 <ul>
4873 <li>Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4874 code for the check when dropping a table or database. He also suggested
4875 that you should be able to specify the primary key on tbl_create.php3. To
4876 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4877 well as a bug-report. Plus many smaller improvements.
4878 </li>
4879 <li>Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4880 were introduced in 1.3.0 (including quite significant ones like the
4881 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4882 bug-fixes and help.
4883 </li>
4884 <li>Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4885 language-independent by outsourcing the strings to a separate file. He
4886 also contributed the French translation.
4887 </li>
4888 <li>Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4889 tbl_select.php3, a feature to display only some columns from a table.
4890 </li>
4891 <li>Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4892 functions in tbl_change.php3. He also added the
4893 &quot;Query by Example&quot; feature in 2.0.
4894 </li>
4895 <li>Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4896 servers and is a regular contributor for bug-fixes.
4897 </li>
4898 <li>Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4899 features for 2.0.6.
4900 </li>
4901 </ul>
