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

132 <h4>A word about users:</h4>
133 <p> Many people have difficulty
134 understanding the concept of user management with regards to phpMyAdmin. When
135 a user logs in to phpMyAdmin, that username and password are passed directly
136 to MySQL. phpMyAdmin does no account management on its own (other than
137 allowing one to manipulate the MySQL user account information); all users
138 must be valid MySQL users.</p>
140 <p class="footnote" id="footnote_1">
141 <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
142 dumps and <abbr title="comma seperated values">CSV</abbr> exports if you use
143 PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
144 (<tt>--with-bz2</tt>). Proper support may also need changes in
145 <tt>php.ini</tt>.</p>

155 </ol>
157 <p class="important">
158 phpMyAdmin does not apply any special security methods to the MySQL database
159 server. It is still the system administrator's job to grant permissions on
160 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
161 be used for this.
162 </p>
164 <p class="important">
165 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
166 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
167 <abbr title="operating system">OS</abbr> version before
168 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
169 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
170 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
171 before uploading them to your server, as PHP seems not to like
172 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
173 (&quot;<tt>\r</tt>&quot;).</p>
175 <h3 id="quick_install">Quick Install</h3>
176 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
177 Downloads page. Some kits contain only the English messages,
178 others contain all languages in UTF-8 format (this should be fine
179 in most situations), others contain all
180 languages and all character sets. We'll assume you chose a kit whose
181 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
182 </li>
183 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
184 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
185 document root. If you don't have direct access to your document root,
186 put the files in a directory on your local machine, and, after step 4,
187 transfer the directory on your web server using, for example, ftp.</li>
188 <li>Ensure that all the scripts have the appropriate owner (if PHP is
189 running in safe mode, having some scripts with an owner different
190 from the owner of other scripts will be a
191 problem). See <a href="#faq4_2">
192 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
193 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
194 1.26</a> for suggestions.</li>
195 <li>Now you must configure your installation. There are two methods that
196 can be used. Traditionally, users have hand-edited a copy of
197 <tt>config.inc.php</tt>, but now a wizard-style setup script is
198 provided for those who prefer a graphical installation. Creating a
199 <tt>config.inc.php</tt> file is
200 still a quick way to get started and needed for some advanced features.
201 <ul><li>To manually create the file, simply use your text editor to
202 create the file <tt>config.inc.php</tt> (you can copy
203 <tt>config.sample.inc.php</tt> to get minimal configuration
204 file) in the main (top-level) phpMyAdmin directory (the one
205 that contains <tt>index.php</tt>). phpMyAdmin first loads
206 <tt>libraries/config.default.php</tt> and then overrides those
207 values with anything found in <tt>config.inc.php</tt>. If the
208 default value is okay for a particular setting, there is no
209 need to include it in <tt>config.inc.php</tt>. You'll need a
210 few directives to get going, a simple configuration may look
211 like this:
212 <pre>
213 &lt;?php
214 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
216 $i=0;
217 $i++;
218 $cfg['Servers'][$i]['auth_type'] = 'cookie';
219 ?&gt;
220 </pre>
221 Or, if you prefer to not be prompted every time you log in:
222 <pre>
223 &lt;?php
225 $i=0;
226 $i++;
227 $cfg['Servers'][$i]['user'] = 'root';
228 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
229 ?&gt;
230 </pre>
231 For a full explanation of possible configuration values, see the
232 <a href="#config">Configuration Section</a> of this document.</li>
233 <li id="setup_script">Instead of manually editing
234 <tt>config.inc.php</tt>, you can use the
235 <a href="scripts/setup.php">Setup Script</a>. First you must
236 manually create a folder <tt>config</tt> in the phpMyAdmin
237 directory. This is a security measure. On a Linux/Unix system you
238 can use the following commands:
239 <pre>
240 cd phpMyAdmin
241 mkdir config # create directory for saving
242 chmod o+rw config # give it world writable permissions
243 </pre>
244 And to edit an existing configuration, copy it over first:
245 <pre>
246 cp config.inc.php config/ # copy current configuration for editing
247 chmod o+w config/config.inc.php # give it world writable permissions
248 </pre>
249 On other platforms, simply create the folder and ensure that your
250 web server has read and write access to it. <a href="#faq1_26">FAQ
251 1.26</a> can help with this.<br /><br />
253 Next, open <tt><a href="scripts/setup.php">scripts/setup.php</a>
254 </tt>in your browser. Note that <strong>changes are not saved to
255 disk until explicitly choose <tt>Save</tt></strong> from the
256 <i>Configuration</i> area of the screen. Normally the script saves
257 the new config.inc.php to the <tt>config/</tt> directory, but if
258 the webserver does not have the proper permissions you may see the
259 error "Cannot load or save configuration." Ensure that the <tt>
260 config/</tt> directory exists and has the proper permissions -
261 or use the <tt>Download</tt> link to save the config file locally
262 and upload (via FTP or some similar means) to the proper location.<br /><br />
264 Once the file has been saved, it must be moved out of the <tt>
265 config/</tt> directory and the permissions must be reset, again
266 as a security measure:
267 <pre>
268 mv config/config.inc.php . # move file to current directory
269 chmod o-rw config.inc.php # remove world read and write permissions
270 </pre>
271 Now the file is ready to be used. You can choose to review or edit
272 the file with your favorite editor, if you prefer to set some
273 advanced options which the setup script does not provide.</li></ul></li>
274 <li>If you are using the
275 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
276 protect the phpMyAdmin installation directory because using
277 config does not require a user to
278 enter a password to access the phpMyAdmin installation. Use of an alternate
279 authentication method is recommended, for example with
280 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
281 <tt>auth_type</tt> cookie or http. See the
282 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
283 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
284 information, especially <a href="#faq4_4">
285 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
286 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
287 in your browser. phpMyAdmin should now display a welcome screen
288 and your databases, or a login dialog if using
289 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
290 authentication mode.</li>
291 <li>You should deny access to the <tt>./libraries</tt> subfolder in your
292 webserver configuration. For Apache you can use supplied .htaccess file
293 in that folder, for other webservers, you should configure this yourself.
294 Such configuration prevents from possible path exposure and cross side
295 scripting vulnerabilities that might happen to be found in that code.</li>
296 </ol>
298 <h3 id="linked-tables">Linked-tables infrastructure</h3>
300 <p> For a whole set of new features (bookmarks, comments,
301 <abbr title="structured query language">SQL</abbr>-history,
302 <abbr title="Portable Document Format">PDF</abbr>-generation, field contents
303 transformation, etc.) you need to create a set of special tables. Those
304 tables can be located in your own database, or in a central database for a
305 multi-user installation (this database would then be accessed by the
306 controluser, so no other user should have rights to it).</p>
308 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
309 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
310 special attention to <a href="#faq1_23">
311 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
313 <p> If your MySQL server's version is 4.1.2 or later, please use
314 <i>./scripts/create_tables_mysql_4_1_2+.sql</i> instead, for a new
315 installation.</p>
317 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
318 or later, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>.</p>
320 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
321 that you may need special (administrator) privileges to create the database
322 and tables, and that the script may need some tuning, depending on the
323 database name.</p>
325 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
326 should specify the table names in your <i>./config.inc.php</i> file. The
327 directives used for that can be found in the <a href="#config">Configuration
328 section</a>. You will also need to have a controluser with the proper rights
329 to those tables (see section <a href="#authentication_modes">Using
330 authentication modes</a> below).</p>
332 <h3 id="upgrading">Upgrading from an older version</h3>
334 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
335 unpacked one. Configuration files from very old versions (2.3.0 or before) may
336 require some tweaking as some options have been changed or removed.
337 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
338 statement that you might find near the end of your configuration file.</p>
340 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
341 over <tt>config.inc.php</tt> because the default configuration file
342 is version-specific.</p>
344 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
345 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
346 you should run the SQL script found in
347 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
349 <h3 id="authentication_modes">Using authentication modes</h3>
351 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
352 authentication modes are recommended in a <b>multi-user environment</b>
353 where you want to give users access to their own database and don't want
354 them to play around with others.<br />
355 Nevertheless be aware that MS Internet Explorer seems to be really buggy
356 about cookies, at least till version 6, and PHP 4.1.1 is also a bit buggy
357 in this area!<br />
358 Even in a <b>single-user environment</b>, you might prefer to use
359 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
360 that your user/password pair are not in clear in the configuration file.
361 </li>
363 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
364 authentication modes are more secure: the MySQL login information does
365 not need to be set in the phpMyAdmin configuration file (except possibly
366 for the <a href="#controluser">controluser</a>).<br />
367 However, keep in mind that the password travels in plain text, unless
368 you are using the HTTPS protocol.<br />
369 In cookie mode, the password is stored, encrypted with the blowfish
370 algorithm, in a temporary cookie.</li>
372 <li>Note: starting with phpMyAdmin 2.6.1, this section is only applicable if
373 your MySQL server is previous to 4.1.2, or is running with
374 <tt>--skip-show-database</tt>.<br /><br />
376 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
377 modes, phpMyAdmin needs a controluser that has <b>only</b> the
378 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
379 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
380 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
381 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
382 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
383 file under the
384 <tt><a href="#cfg_Servers_controluser" class="configrule">
385 $cfg['Servers'][$i]['controluser']</a></tt> and
386 <tt><a href="#cfg_Servers_controlpass" class="configrule">
387 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
388 The following example assumes you want to use <tt>pma</tt> as the
389 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
390 only an example: use something else in your file!</b> Input these
391 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
392 client.<br />
393 Of course you have to replace <tt>localhost</tt> with the webserver's host
394 if it's not the same as the MySQL server's one.
396 <pre>
397 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
398 GRANT SELECT (
399 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
400 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
401 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
402 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
403 Execute_priv, Repl_slave_priv, Repl_client_priv
404 ) ON mysql.user TO 'pma'@'localhost';
405 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
406 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
407 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
408 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
410 If you are using an old MySQL version (below 4.0.2), please replace
411 the first GRANT SELECT query by this one:
413 <pre>
414 GRANT SELECT (
415 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
416 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
417 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv
418 ) ON mysql.user TO 'pma'@'localhost';</pre>
420 ... and if you want to use the many new relation and bookmark features:
422 <pre>
423 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
424 </pre>
426 (this of course requires that your <a href="#linked-tables">linked-tables
427 infrastructure</a> be set up).<br />
428 Of course, the above queries only work if your MySQL version supports
429 the GRANT command. This is the case since 3.22.11.</li>
431 <li>Then each of the <i>true</i> users should be granted a set of privileges
432 on a set of particular databases. Normally you shouldn't give global
433 privileges to an ordinary user, unless you understand the impact of those
434 privileges (for example, you are creating a superuser).<br />
435 For example, to grant the user <i>real_user</i> with all privileges on
436 the database <i>user_base</i>:<br />
438 <pre>
439 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
440 </pre>
442 What the user may now do is controlled entirely by the MySQL user
443 management system.<br />
444 With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
445 authentication mode, you don't need to fill the user/password fields
446 inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
447 array.</li>
448 </ul>
450 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>

464 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a> about not
465 using the <i>.htaccess</i> mechanism along with
466 '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication
467 mode.</li>
468 </ul>
470 <h4>'cookie' authentication mode</h4>
472 <ul><li>You can use this method as a replacement for the
473 <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
474 (for example, if you're running
475 <abbr title="Internet Information Services">IIS</abbr>).</li>
476 <li>Obviously, the user must enable cookies in the browser, but this is
477 now a requirement for all authentication modes.</li>
478 <li>With this mode, the user can truly log out of phpMyAdmin and log in back
479 with the same username.</li>
480 <li>If you want to log in to arbitrary server see
481 <a href="#AllowArbitraryServer" class="configrule">
482 $cfg['AllowArbitraryServer']</a> directive.</li>
483 <li>As mentioned in the <a href="#require">requirements</a> section, having
484 the <tt>mcrypt</tt> extension will speed up access considerably, but is
485 not required.</li>
486 </ul>
488 <h4>'signon' authentication mode</h4>
490 <ul><li>This mode is a convenient way of using credentials from another
491 application to authenticate to phpMyAdmin.</li>
492 <li>The other application has to store login information into
493 session data.</li>
494 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
495 section.</li>
496 </ul>
497 <h4>'config' authentication mode</h4>
499 <ul><li>This mode is the less secure one because it requires you to fill the
500 <a href="#servers_user" class="configrule">
501 $cfg['Servers'][$i]['user']</a> and
502 <a href="#servers_user" class="configrule">
503 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
504 can read your config.inc.php can discover your username and password).
505 <br />
506 But you don't need to setup a &quot;controluser&quot; here: using the
507 <a href="#servers_only_db" class="configrule">
508 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
509 <li>In the <a href="#faqmultiuser">
510 <abbr title="Internet service provider">ISP</abbr>
511 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
512 is an entry explaining how to protect your configuration file.</li>
513 <li>For additional security in this mode, you may wish to consider the Host
514 authentication
515 <a href="#servers_allowdeny_order" class="configrule">
516 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
517 <a href="#servers_allowdeny_rules" class="configrule">
518 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
519 directives.</li>
520 <li>Unlike cookie and http, does not require a user to log in when first
521 loading the phpMyAdmin site. This is by design but could allow any
522 user to access your installation. Use of some restriction method is
523 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
524 HTTP-AUTH directive or disallowing incoming HTTP requests at
525 one&#8217;s router or firewall will suffice (both of which
526 are beyond the scope of this manual but easily searchable with Google).</li>
527 </ul>

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

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

699 <li>'cookie' authentication mode
700 (<tt>$auth_type&nbsp;=&nbsp;'cookie'</tt>) as introduced in
701 2.2.3 allows you to log in as any valid MySQL user with the
702 help of cookies. Username and password are stored in
703 cookies during the session and password is deleted when it
704 ends. This can also allow you to log in in arbitrary server if

710 <li>'signon' authentication mode
711 (<tt>$auth_type&nbsp;=&nbsp;'signon'</tt>)
712 as introduced in 2.10.0 allows you to log in from prepared PHP

714 from another application. Sample way how to seed session is in
715 signon example: <code>scripts/signon.php</code>. You need to
716 configure <a href="#cfg_Servers_SignonSession"

749 If set to a (an array of) database name(s), only this (these) database(s)
750 will be shown to the user. Since phpMyAdmin 2.2.1, this/these
751 database(s) name(s) may contain MySQL wildcards characters
752 (&quot;_&quot; and &quot;%&quot;): if you want to use literal instances
753 of these characters, escape them (I.E. use <tt>'my\_db'</tt> and not
754 <tt>'my_db'</tt>).<br />
755 This setting is an efficient way to lower the server load since the
756 latter does not need to send MySQL requests to build the available
757 database list. But <span class="important">it does not replace the
758 privileges rules of the MySQL database server</span>. If set, it just
759 means only these databases will be displayed but
760 <span class="important">not that all other databases can't be used.</span>

763 An example of using more that one database:
764 <tt>$cfg['Servers'][$i]['only_db'] = array('db1', 'db2');</tt>
765 <br /><br />
767 As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
768 databases in the left frame, so that you can individually arrange your databases.<br />
769 If you want to have certain databases at the top, but don't care about the others, you do not
770 need to specify all other databases. Use:
771 <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>
772 instead to tell phpMyAdmin that it should display db3 and db4 on top, and the rest in alphabetic

777 <dd>Regular expression for hiding some databases. This only hides them
778 from listing, but a user is still able to access them (using, for example,
779 the SQL query area). To limit access, use the MySQL privilege system.
780 <br /><br />
781 For example, to hide all databases starting with the letter &#34;a&#34;, use<br />
782 <pre>$cfg['Servers'][$i]['hide_db'] = '^a';</pre>
783 and to hide both &#34;db1&#34; and &#34;db2&#34; use <br />
784 <pre>$cfg['Servers'][$i]['hide_db'] = '(db1|db2)';</pre>

909 infrastructure</li>
910 <li>put the correct table names in

921 <dd><!-- This part requires a content update! -->
922 Since release 2.3.0 you can store comments to describe each column for
923 each table. These will then be shown on the &quot;printview&quot;.
924 <br /><br />
926 Starting with release 2.5.0, comments are consequently used on the table
927 property pages and table browse view, showing up as tool-tips above the
928 column name (properties page) or embedded within the header of table in
929 browse view. They can also be shown in a table dump. Please see the
930 relevant configuration directives later on.<br /><br />
932 Also new in release 2.5.0 is a MIME-transformation system which is also
933 based on the following table structure. See <a href="#transformations">
934 Transformations</a> for further information. To use the
935 MIME-transformation system, your column_info table has to have the three
936 new fields 'mimetype', 'transformation', 'transformation_options'.
937 <br /><br />
939 To allow the usage of this functionality:
940 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables
941 infrastructure</li>
942 <li>put the table name in
943 <tt>$cfg['Servers'][$i]['column_info']</tt></li>
944 <li>to update your PRE-2.5.0 Column_comments Table use this:
946 <pre>
947 ALTER TABLE `pma_column_comments`
948 ADD `mimetype` VARCHAR( 255 ) NOT NULL,
949 ADD `transformation` VARCHAR( 255 ) NOT NULL,
950 ADD `transformation_options` VARCHAR( 255 ) NOT NULL;
951 </pre>
953 and remember that the Variable in <i>config.inc.php</i> has been
954 renamed from<br />

963 <dd>Since release 2.5.0 you can store your
964 <abbr title="structured query language">SQL</abbr> history, which means
965 all queries you entered manually into the phpMyAdmin interface. If you
966 don't want to use a table-based history, you can use the JavaScript-based
967 history. Using that, all your history items are deleted when closing the
968 window.<br /><br />
970 Using
971 <a href="#cfg_QueryHistoryMax" class="configrule">$cfg['QueryHistoryMax']</a>
972 you can specify an amount of history items you want to have on hold. On

1011 You can disable this checking behavior by setting the variable to false,

1024 authentication is disabled.<br /><br />
1026 If your rule order is set to <tt>'deny,allow'</tt> then the system applies
1027 all deny rules followed by allow rules. Access is allowed by default. Any
1028 client which does not match a Deny command or does match an Allow command
1029 will be allowed access to the server. <br /><br />
1031 If your rule order is set to <tt>'allow,deny'</tt> then the system
1032 applies all allow rules followed by deny rules. Access is denied by
1033 default. Any client which does not match an Allow directive or does
1034 match a Deny directive will be denied access to the server.<br /><br />
1036 If your rule order is set to 'explicit', the authentication is
1037 performed in a similar fashion to rule order 'deny,allow', with the
1038 added restriction that your host/username combination <b>must</b> be
1039 listed in the <i>allow</i> rules, and not listed in the <i>deny</i>
1040 rules. This is the <b>most</b> secure means of using Allow/Deny rules,
1041 and was available in Apache by specifying allow and deny rules without
1042 setting any order.<br /><br />

1057 If you wish to match all users, it is possible to use a <tt>'%'</tt> as

1067 'localnetC' -&gt; SERVER_ADDRESS/24

1070 Having an empty rule list is equivalent to either using
1071 <tt>'allow % from all'</tt> if your rule order is set to

1248 'user0001' and add the comment 'MyName' on it, you will see the name
1249 'MyName' used consequently in the left frame and the tool-tip shows
1250 the real name of the DB.</dd>

1256 to split/nest the tables according to the
1257 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1258 directive. So only the folder is called like the Alias, the tablename itself
1259 stays the real tablename.</dd>

1799 JavaScript enabled browser. Basic functions are used to exchange quite
1800 a few variables, so most 4th generation browsers should be capable to
1801 use that feature. It currently is only tested with Internet Explorer 6
1802 and Mozilla 1.x.
1803 <br /><br />
1804 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
1805 to a table, which has to be created by you (see <a
1806 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
1807 all your queries will be appended to the form, but only as long as
1808 your window is opened they remain saved.
1809 <br /><br />
1810 When using the JavaScript based query window, it will always get
1811 updated when you click on a new table/db to browse and will focus if
1812 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
1813 the query window by checking the box "Do not overwrite this query from
1814 outside the window" below the query textarea. Then you can browse
1815 tables/databases in the background without losing the contents of the
1816 textarea, so this is especially useful when composing a query with
1817 tables you first have to look in. The checkbox will get automatically
1818 checked whenever you change the contents of the textarea. Please
1819 uncheck the button whenever you definitely want the query window to
1820 get updated even though you have made alterations.
1821 <br /><br />
1822 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
1823 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
1824 <br /><br />
1825 The query window also has a custom tabbed look to group the features.
1826 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
1827 default tab to be used when opening the query window. It can be set to
1828 either 'sql', 'files', 'history' or 'full'.</dd>

1852 page. By clicking on the button 'toggle scratchboard' on the page
1853 where you edit x/y coordinates of those elements you can activate a
1854 scratchboard where all your elements are placed. By clicking on an
1855 element, you can move them around in the pre-defined area and the x/y
1856 coordinates will get updated dynamically. Likewise, when entering a
1857 new position directly into the input field, the new position in the
1858 scratchboard changes after your cursor leaves the input field.<br />
1859 You have to click on the 'OK'-button below the tables to save the new
1860 positions. If you want to place a new element, first add it to the
1861 table of elements and then you can drag the new element around.<br />
1862 By changing the paper size and the orientation you can change the size
1863 of the scratchboard as well. You can do so by just changing the
1864 dropdown field below, and the scratchboard will resize automatically,
1865 without interfering with the current placement of the elements.<br />
1866 If ever an element gets out of range you can either enlarge the paper
1867 size or click on the 'reset' button to place all elements below each
1868 other.<br />

2083 <ol><li><a href="#transformationsintro">Introduction</a></li>
2084 <li><a href="#transformationshowto">Usage</a></li>
2085 <li><a href="#transformationsfiles">File structure</a></li>
2086 </ol>
2088 <h3 id="transformationsintro">1. Introduction</h3>
2090 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2091 and the proper directives. Please see the <a href="#config">Configuration
2092 section</a> on how to do so.</p>
2094 <p> You can apply different transformations to the contents of each field. The
2095 transformation will take the content of each field and transform it with
2096 certain rules defined in the selected transformation.</p>
2098 <p> Say you have a field 'filename' which contains a filename. Normally you would
2099 see in phpMyAdmin only this filename. Using transformations you can transform
2100 that filename into a HTML link, so you can click inside of the phpMyAdmin
2101 structure on the field's link and will see the file displayed in a new browser
2102 window. Using transformation options you can also specify strings to
2103 append/prepend to a string or the format you want the output stored in.</p>
2105 <p> For a general overview of all available transformations and their options,
2106 you can consult your
2107 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2108 installation.</p>
2110 <p> For a tutorial on how to effectively use transformations, see our
2111 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2112 the official phpMyAdmin homepage.</p>
2114 <h3 id="transformationshowto">2. Usage</h3>
2116 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2117 clicking on the 'Structure' link for a table). There click on
2118 &quot;Change&quot; (or change icon) and there you will see three new fields at
2119 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2120 'Transformation options'.</p>
2122 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2123 that corresponds to the column's contents. Please note that
2124 transformations are inactive as long as no MIME-type is selected.</li>
2126 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2127 hopefully growing amount of pre-defined transformations. See below for information on
2128 how to build your own transformation.<br />
2130 There are global transformations and mimetype-bound transformations. Global transformations
2131 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2132 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2133 transformations which operate on the main mimetype (like 'image'), which will most likely
2134 take the subtype into regard, and those who only operate on a
2135 specific subtype (like 'image/jpeg').<br />
2137 You can use transformations on mimetypes for which the function was not defined for. There
2138 is no security check for you selected the right transformation, so take care of what the
2139 output will be like.</li>
2141 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2142 transform-function specific options here. Usually the transforms can operate with default
2143 options, but it is generally a good idea to look up the overview to see which options are
2144 necessary.<br />
2146 Much like the ENUM/SET-Fields, you have to split up several options using the format
2147 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2148 parsed as an array, leaving the first value the first element in the array, and so
2149 forth.<br />
2151 If you want to specify a MIME character set you can define it in the transformation_options.
2152 You have to put that outside of the pre-defined options of the specific mime-transform,
2153 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2154 for which you can specify 2 options and you want to append a character set, enter "'first
2155 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2156 the parameters: "'','','charset=us-ascii'".</li>
2157 </ul>
2159 <h3 id="transformationsfiles">3. File structure</h3>
2161 <p> All mimetypes and their transformations are defined through single files in
2162 the directory 'libraries/transformations/'.</p>
2164 <p> They are stored in files to ease up customization and easy adding of new
2165 transformations.</p>
2167 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2168 always work. It makes no sense to apply a transformation to a mimetype, the
2169 transform-function doesn't know to handle.</p>
2171 <p> One can, however, use empty mime-types and global transformations which should work
2172 for many mimetypes. You can also use transforms on a different mimetype they where built
2173 for, but pay attention to option usage as well as what the transformation does to your
2174 field.</p>
2176 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2177 any other transform function and provides some basic functions.</p>
2179 <p> There are 5 possible file names:</p>
2181 <ol><li>A mimetype+subtype transform:<br /><br />
2183 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2185 Please not that mimetype and subtype are separated via '_', which shall
2186 not be contained in their names. The transform function/filename may
2187 contain only characters which cause no problems in the file system as
2188 well as the PHP function naming convention.<br /><br />
2190 The transform function will the be called
2191 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2193 <b>Example:</b><br /><br />
2195 <tt>text_html__formatted.inc.php</tt><br />
2196 <tt>PMA_transform_text_html__formatted()</tt></li>
2198 <li>A mimetype (w/o subtype) transform:<br /><br />
2200 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2202 Please note that there are no single '_' characters.
2203 The transform function/filename may contain only characters which cause
2204 no problems in the file system as well as the PHP function naming
2205 convention.<br /><br />
2207 The transform function will the be called
2208 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2210 <b>Example:</b><br /><br />
2212 <tt>text__formatted.inc.php</tt><br />
2213 <tt>PMA_transform_text__formatted()</tt></li>
2215 <li>A mimetype+subtype without specific transform function<br /><br />
2217 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2219 Please note that there are no '__' characters in the filename. Do not
2220 use special characters in the filename causing problems with the file
2221 system.<br /><br />
2223 No transformation function is defined in the file itself.<br /><br />
2225 <b>Example:</b><br /><br />
2227 <tt>text_plain.inc.php</tt><br />
2228 (No function)</li>
2230 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2232 <tt>[mimetype].inc.php</tt><br /><br />
2234 Please note that there are no '_' characters in the filename. Do not use
2235 special characters in the filename causing problems with the file system.
2236 <br /><br />
2238 No transformation function is defined in the file itself.<br /><br />
2240 <b>Example:</b><br /><br />
2242 <tt>text.inc.php</tt><br />
2243 (No function)</li>
2245 <li>A global transform function with no specific mimetype<br /><br />
2247 <tt>global__[transform].inc.php</tt><br /><br />
2249 The transform function will the be called
2250 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2252 <b>Example:</b><br /><br />
2254 <tt>global__formatted</tt><br />

2258 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2259 transform function.</p>
2261 <p> All filenames containing no '__' in themselves are not shown as valid transform
2262 functions in the dropdown.</p>
2264 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2265 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2266 without a transform function. Also note the introduction of a function description in
2267 the language files. For each function a $strTransformation_[filename without .inc.php]
2268 has to exist.</p>
2270 <p> You can use the template generator to generate new functions and entries in the
2271 language file.</p>
2273 <p> To create a new transform function please see
2274 <tt>libraries/transformations/template_generator.sh</tt>.
2275 To create a new, empty mimetype please see
2276 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2278 <p> A transform function always gets passed three variables:</p>
2280 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2281 you want to transform.</li>
2282 <li><b>$options</b> - Contains any user-passed options to a transform function
2283 as an array.</li>
2284 <li><b>$meta</b> - Contains an object with field information to your column.
2285 The data is drawn from the output of the
2286 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2287 function. This means, all object properties described on the
2288 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2289 available in this variable and can be used to transform a field accordingly
2290 to unsigned/zerofill/not_null/... properties.<br />
2291 The $meta-&gt;mimetype variable contains the original MIME-type of the
2292 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>

2449 <p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir
2450 restrictions. Assuming that the restriction allows you to open files in the
2451 current directory ('.'), all you have to do is create a 'tmp' directory
2452 under the phpMyAdmin install directory, with permissions 777 and the same
2453 owner as the owner of your phpMyAdmin directory. The uploaded files will

2489 <a href="#faq1_16">1.16 I cannot upload big dump files (memory,
2490 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or timeout problems).</a>
2491 </h4>
2493 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2494 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2495 to take advantage of the new import features.</p>
2497 <p> The first things to check (or ask your host provider to check) are the
2498 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2499 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2500 All of these three settings limit the maximum size of data that can be
2501 submitted and handled by PHP. One user also said that post_max_size
2502 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2504 There exist several workarounds if your upload is too big or your
2505 hosting provider is unwilling to change the settings:</p>
2507 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2508 feature. This allows one to
2509 upload a file to the server via scp, ftp, or your favorite file transfer
2510 method. PhpMyAdmin is then able to import the files from the temporary
2511 directory. More information is available in the <a href="#config">Configuration
2512 section</a> of this document.</li>
2513 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2514 BigDump</a>) to split the files before uploading. We cannot support this
2515 or any third party applications, but are aware of users having success
2516 with it.</li>
2517 <li>If you have shell (command line) access, use MySQL to import the files
2518 directly. You can do this by issuing the &quot;source&quot; command from
2519 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2520 </ul>
2522 <h4 id="faq1_17">
2523 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2524 support?</a></h4>
2526 <p> All MySQL versions from 3.23.32 till 5.0 (except for 4.1.0 and 4.1.1) are
2527 fully supported. Please note that the older your MySQL version is, the more
2528 limitations you will have to face.<br />
2529 phpMyAdmin may connect to your MySQL server using php's classic
2530 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2531 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2532 is available in php 5.0.<br />
2533 Either way, the developers of both extensions recommend to use the classic
2534 extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and newer.<br />
2535 When compiling php, we strongly recommend that you manually link the MySQL
2536 extension of your choice to a MySQL client library of at least the same
2537 minor version since the one that is bundled with some php distributions is
2538 rather old and might cause problems <a href="#faq1_17a">
2539 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.
2540 If your webserver is running on a windows system, you might want to try
2541 MySQL's
2542 <a href="http://dev.mysql.com/downloads/connector/php/">Connector/PHP</a>
2543 instead of the MySQL / MySQLi extensions that are bundled with the official
2544 php Win32 builds.

2550 message, &quot;Client does not support authentication protocol requested

2553 <p> You tried to access MySQL with an old MySQL client library. The version of
2554 your MySQL client library can be checked in your phpinfo() output.
2555 In general, it should have at least the same minor version as your server
2556 - as mentioned in <a href="#faq1_17">
2557 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2559 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2560 changed the authentication hash and your PHP is trying to use the old method.
2561 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2562 with the proper client library to match your MySQL installation. Your
2563 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2594 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2595 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried

2848 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
2850 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
2851 In your <i>php.ini</i> you will find a line</p>
2853 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
2855 <p> change it to</p>
2857 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
2859 <p> Then restart apache and it will work.</p>
2861 <p> Here is a fix suggested by Brad Ummer:</p>
2863 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
2864 To do this, telnet to your server and go to the MySQL bin directory. In
2865 this directory there should be a file named <i>mysqladmin</i>. Type
2866 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
2867 info about your MySQL server, including the socket
2868 (<i>/tmp/mysql.sock</i>, for example).</li>
2869 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
2870 phpMyAdmin, you need to complete the socket information in the
2871 <i>config.inc.php</i>.<br />
2872 For example:
2873 <a href="#cfg_Servers_socket" class="configrule">
2874 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
2875 <br /><br />
2877 Please also make sure that the permissions of this file allow to be readable
2878 by your webserver (i.e. '0755').</li>
2879 </ul>
2881 <p> Have also a look at the
2882 <a href="http://www.mysql.com/doc/C/a/Can_not_connect_to_server.html">

2910 <p> When you are using a port on your localhost, which you redirect via
2911 port-forwarding to another host, MySQL is not resolving the localhost
2912 as expected.<br />
2913 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
2914 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
2915 connection for speeding up things. And that doesn't work in this configuration
2916 with port forwarding.<br />

2924 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
2925 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
2926 <br />
2927 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
2928 should not delete the directory &quot;original&quot; or its underlying
2929 structure, because this is the system theme used by phpMyAdmin.
2930 &quot;original&quot; contains all images and styles, for backwards
2931 compatibility and for all themes that would not include images or css-files.
2932 <br /><br />
2934 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
2935 is enabled, you can select your favorite theme on the main page. Your
2936 selected theme will be stored in a cookie.<br /><br /></p>
2938 <p> To create a theme:</p>
2940 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
2941 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
2942 (by default <tt>themes</tt>)</li>
2943 <li>copy the files and directories from &quot;original&quot; to
2944 &quot;your_theme_name&quot;</li>
2945 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
2946 <li>put your new images in &quot;your_theme_name/img&quot;</li>
2947 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
2948 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
2949 contain your chosen theme name, that will be visible in user interface</li>
2950 <li>make a new screenshot of your theme and save it under
2951 &quot;your_theme_name/screen.png&quot;</li>
2952 </ul>
2954 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
2955 theme verbose name, theme generation and theme version. These versions and
2956 generations are enumerated from 1 and do not have any direct dependence on
2957 phpMyAdmin version. Themes within same generation should be backwards
2958 compatible - theme with version 2 should work in phpMyAdmin requiring
2959 version 1. Themes with different generation are incompatible.</p>
2961 <p> If you do not want to use your own symbols and buttons, remove the
2962 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
2963 use the default icons and buttons (from the system-theme &quot;original&quot;).

3129 <p> phpMyAdmin uses a quick method to get the row count, and this method
3130 only returns an approximate count in the case of InnoDB tables. See

3167 Since version 2.0.3, you can setup a central copy of phpMyAdmin for all

3177 access.
3178 </a></h4>
3180 This depends on your system.<br />
3181 If you're running a server which cannot be accessed by other people, it's
3182 sufficient to use the directory protection bundled with your webserver
3183 (with Apache you can use <i>.htaccess</i> files, for example).<br />
3184 If other people have telnet access to your server, you should use
3185 phpMyAdmin's <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication features.
3186 <br /><br />
3187 Suggestions:
3188 </p>
3189 <ul>
3190 <li>
3191 Your <i>config.inc.php</i> file should be <tt>chmod 660</tt>.
3192 </li>
3193 <li>
3194 All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
3195 is a user whose password is only known to you, and apache is the
3196 group under which Apache runs.
3197 </li>
3198 <li>
3199 You should use PHP safe mode, to protect from other users that try
3200 to include your <i>config.inc.php</i> in their scripts.

3205 <a href="#faq4_3">4.3 I get errors about not being able to include a file in

3207 </a></h4>
3209 Check <i>php.ini</i>, or ask your sysadmin to check it. The
3210 <tt>include_path</tt> must contain &quot;.&quot; somewhere in it, and
3211 <tt>open_basedir</tt>, if used, must contain &quot;.&quot; and

3226 <li>The username/password you specify in the login dialog are invalid.</li>
3227 <li>You have already setup a security mechanism for the

3236 database name for a user (for example &quot;joe%&quot;),
3237 and put the privileges you want. For example,
3238 adding <tt>SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER</tt>

3599 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3601 First the configuration variables &quot;relation&quot;,
3602 &quot;table_coords&quot; and &quot;pdf_pages&quot; have to be filled in.
3603 <br /><br />
3604 Then you need to think about your schema layout. Which tables will go on
3605 which pages?
3606 </p>
3607 <ul>
3608 <li>Select your database in the left frame.</li>
3609 <li>Choose &quot;Operations&quot; in the navigation bar at the top.</li>
3610 <li>Choose &quot;Edit <abbr title="Portable Document Format">PDF</abbr>
3611 Pages&quot; near the bottom of the page.</li>
3612 <li>Enter a name for the first <abbr title="Portable Document Format">PDF</abbr>
3613 page and click Go. If you like, you
3614 can use the &quot;automatic layout,&quot; which will put all your
3615 linked tables onto the new page.</li>
3616 <li>Select the name of the new page (making sure the Edit radio button
3617 is selected) and click Go.</li>
3618 <li>Select a table from the list, enter its coordinates and click Save.<br />
3619 Coordinates are relative; your diagram will
3620 be automatically scaled to fit the page. When initially placing tables
3621 on the page, just pick any coordinates -- say, 50x50. After clicking
3622 Save, you can then use the <a href="#wysiwyg">graphical editor</a> to
3623 position the element correctly.</li>
3624 <li>When you'd like to look at your <abbr title="Portable Document Format">PDF</abbr>,
3625 first be sure to click the Save
3626 button beneath the list of tables and coordinates, to save any changes
3627 you made there. Then scroll all the way down, select the
3628 <abbr title="Portable Document Format">PDF</abbr> options
3629 you want, and click Go.</li>
3630 <li>Internet Explorer for Windows may suggest an incorrect filename when
3631 you try to save a generated <abbr title="Portable Document Format">PDF</abbr>.
3632 When saving a generated <abbr title="Portable Document Format">PDF</abbr>, be
3633 sure that the filename ends in &quot;.pdf&quot;, for example
3634 &quot;schema.pdf&quot;. Browsers on other operating systems, and other
3635 browsers on Windows, do not have this problem.</li>

3652 database name is &quot;john_db&quot;, the user would get rights to john1db,

3667 <p><b>Structure:</b></p>
3669 <ul><li>&quot;Add DROP TABLE&quot; will add a line telling MySQL to
3670 <a href="http://dev.mysql.com/doc/mysql/en/drop-table.html">drop the table</a>,
3671 if it already exists during the import. It does NOT drop the table after
3672 your export, it only affects the import file.</li>
3673 <li>&quot;If Not Exists&quot; will only create the table if it doesn't exist.
3674 Otherwise, you may get an error if the table name exists but has a
3675 different structure.</li>
3676 <li>&quot;Add AUTO_INCREMENT value&quot; ensures that AUTO_INCREMENT value
3677 (if any) will be included in backup.</li>
3678 <li>&quot;Enclose table and field names with backquotes&quot; ensures that
3679 field and table names formed with special characters are protected.</li>
3680 <li>&quot;Add into comments&quot; includes column comments, relations, and MIME
3681 types set in the pmadb in the dump as
3682 <abbr title="structured query language">SQL</abbr> comments (<i>/* xxx */</i>).
3683 </li>
3684 </ul>
3686 <p><b>Data:</b></p>
3688 <ul><li>&quot;Complete inserts&quot; adds the column names on every INSERT
3689 command, for better documentation (but resulting file is bigger).</li>
3690 <li>&quot;Extended inserts&quot; provides a shorter dump file by using only
3691 once the INSERT verb and the table name.</li>
3692 <li>&quot;Delayed inserts&quot; are best explained in the
3693 <a href="http://dev.mysql.com/doc/mysql/en/insert-delayed.html">MySQL manual</a>.
3694 </li>
3695 <li>&quot;Ignore inserts&quot; treats errors as a warning instead. Again,
3696 more info is provided in the
3697 <a href="http://dev.mysql.com/doc/mysql/en/insert.html">MySQL manual</a>,
3698 but basically with this selected, invalid values are adjusted and
3699 inserted rather than causing the entire statement to fail.</li>

3702 <h4 id="faq6_13">
3703 <a href="#faq6_13">6.13 I would like to create a database with a dot
3704 in its name.</a></h4>
3706 <p> This is a bad idea, because in MySQL the syntax &quot;database.table&quot;
3707 is the normal way to reference a database and table name. Worse, MySQL
3708 will usually let you create a database with a dot, but then you cannot
3709 work with it, nor delete it.</p>
3711 <h4 id="faqsqlvalidator">
3712 <a href="#faqsqlvalidator">6.14 How do I set up the
3713 <abbr title="structured query language">SQL</abbr> Validator?</a></h4>
3715 <p> To use it, you need a very recent version of PHP, 4.3.0 recommended, with
3716 <abbr title="Extensible Markup Language">XML</abbr>,
3717 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
3718 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
3719 On your system command line, run <tt>"pear install Net_Socket Net_URL
3720 HTTP_Request Mail_Mime Net_DIME SOAP"</tt> to get the necessary
3721 <abbr title="PHP Extension and Application Repository">PEAR</abbr> modules
3722 for usage.<br />
3723 On a more recent pear version, I had problems with the state of Net_DIME
3724 being beta, so this single command
3725 <tt>"pear -d preferred_state=beta install -a SOAP"</tt> installed all the
3726 needed modules.<br />
3727 If you use the Validator, you should be aware that any
3728 <abbr title="structured query language">SQL</abbr> statement you
3729 submit will be stored anonymously (database/table/column names,
3730 strings, numbers replaced with generic values). The Mimer
3731 <abbr title="structured query language">SQL</abbr>
3732 Validator itself, is &copy; 2001 Upright Database Technology.
3733 We utilize it as free SOAP service.</p>

3736 <a href="#faq6_15">6.15 I want to add a BLOB field and put an index on
3737 it, but MySQL says &quot;BLOB column '...' used in key specification without
3738 a key length&quot;.</a></h4>
3740 <p> The right way to do this, is to create the field without any indexes,
3741 then display the table structure and use the &quot;Create an index&quot;
3742 dialog. On this page, you will be able to choose your BLOB field, and
3743 set a size to the index, which is the condition to create an index on
3744 a BLOB field.</p>
3746 <h4 id="faq6_16">
3747 <a href="#faq6_16">6.16 How can I simply move in page with plenty
3748 editing fields?</a></h4>
3750 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
3751 with many editing fields (table structure changes, row editing, etc.)
3752 (must be enabled in configuration - see.
3753 <a href="#CtrlArrowsMoving" class="configrule">$cfg['CtrlArrowsMoving']</a>).
3754 You can also have a look at the directive
3755 <a href="#DefaultPropDisplay" class="configrule">$cfg['DefaultPropDisplay']</a>
3756 ('vertical') and see if this eases up editing for you.</p>
3758 <h4 id="faq6_17">
3759 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
3760 WTF is this feature then useful for?</a></h4>
3762 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3763 on them. Otherwise you could just put a comment on the field. Because entering
3764 your own mimetype will cause serious syntax checking issues and validation,
3765 this introduces a high-risk false-user-input situation. Instead you have to
3766 initialize mimetypes using functions or empty mimetype definitions.<br />
3767 Plus, you have a whole overview of available mimetypes. Who knows all those
3768 mimetypes by heart so he/she can enter it at will?</p>
3770 <h4 id="faqbookmark">
3771 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
3772 can't I see any bookmarks below the query box? What is this variable for?
3773 </a></h4>
3775 <p> Any query you have executed can be stored as a bookmark on the page where the
3776 results are displayed. You will find a button labeled 'Bookmark this query'
3777 just at the end of the page.<br />
3778 As soon as you have stored a bookmark, it is related to the database you run
3779 the query on. You can now access a bookmark dropdown on each page, the query
3780 box appears on for that database.<br /><br />
3782 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
3783 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
3784 which is put into the <i>value</i> input box on the query box page will
3785 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
3786 aware of that you HAVE to create a valid query, otherwise your query won't be
3787 even able to be stored in the database.<br />
3788 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
3789 for your query will remain the way it is, but will be stripped of the /**/
3790 chars. So you can use:<br /><br />
3792 <code>/*, [VARIABLE] AS myname */</code><br /><br />
3794 which will be expanded to<br /><br />
3796 <code>, VARIABLE as myname</code><br /><br />
3798 in your query, where VARIABLE is the string you entered in the input box. If
3799 an empty string is provided, no replacements are made.<br /><br />
3801 A more complex example. Say you have stored this query:<br /><br />
3802 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
3803 <br /><br />
3805 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
3806 the full query will be:<br /><br />
3808 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
3809 <br /><br />
3811 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query.<br />
3812 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
3813 spaces inserted there
3814 will be later also inserted as spaces in your query and may lead to unexpected
3815 results especially when
3816 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
3817 Your initial query which is going to be stored as a bookmark has to yield at
3818 least one result row so
3819 you can store the bookmark. You may have that to work around using well
3820 positioned &quot;/**/&quot; comments.</p>
3822 <h4 id="faq6_19">
3823 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
3824 include exported table?</a></h4>
3826 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
3827 document should look like following one (assuming you have table
3828 exported in file <code>table.tex</code>):</p>

3843 <p> Upgrading to MySQL 4 usually gives users those global privileges: CREATE
3844 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
3845 enable users to see all the database names.
3846 See this <a href="http://bugs.mysql.com/179">bug report</a>.<br /><br />

3857 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
3858 6.6</a> for an example. Then, if there are 200 values or less in the
3859 foreign table, a drop-down list of values will be available.
3860 You will see two lists of values, the first list containing the key
3861 and the display field, the second list containing the display field
3862 and the key. The reason for this is to be able to type the first
3863 letter of either the key or the display field.<br /><br />
3865 For 200 values or more, a distinct window will appear, to browse foreign
3866 key values and choose one.</p>

3992 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
3993 great features have been written by other people and you too can help to
3994 make phpMyAdmin a useful tool.</p>
3996 <p> If you're planning to contribute source, please read the following
3997 information:</p>
3999 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
4000 <i>libraries/common.lib.php</i> (common functions) and
4001 <i>config.inc.php</i>.<br />
4002 Only configuration data should go in <i>config.inc.php</i>. Please keep
4003 it free from other code.<br />
4004 Commonly used functions should be added to
4005 <i>libraries/common.lib.php</i> and more specific ones may be added
4006 within a library stored into the <i>libraries</i> sub-directory.</li>
4007 <li>Obviously, you're free to use whatever coding style you want. But
4008 please try to keep your code as simple as possible: beginners are
4009 using phpMyAdmin as an example application.<br />
4010 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4011 compliant on one hand, they fit the

4195 Original Credits of Version 2.1.0
4196 ---------------------------------
4198 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4199 to create a web-based interface to MySQL using PHP3. Although I have not
4200 used any of his source-code, there are some concepts I've borrowed from
4201 him. phpMyAdmin was created because Peter told me he wasn't going to
4202 further develop his (great) tool.
4203 Thanks go to
4204 - Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4205 code for the check when dropping a table or database. He also suggested
4206 that you should be able to specify the primary key on tbl_create.php3. To
4207 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4208 well as a bug-report. Plus many smaller improvements.
4209 - Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4210 were introduced in 1.3.0 (including quite significant ones like the
4211 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4212 bug-fixes and help.
4213 - Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4214 language-independent by outsourcing the strings to a separate file. He
4215 also contributed the French translation.
4216 - Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4217 tbl_select.php3, a feature to display only some fields from a table.
4218 - Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4219 functions in tbl_change.php3. He also added the
4220 &quot;Query by Example&quot; feature in 2.0.
4221 - Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4222 servers and is a regular contributor for bug-fixes.
4223 - Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4224 features for 2.0.6.
4225 The following people have contributed minor changes, enhancements, bugfixes
4226 or support for a new language:
4227 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4228 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4229 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4230 G. Wieggers.
4232 And thanks to everyone else who sent me email with suggestions, bug-reports
4233 and or just some feedback.
