MySQL

&reftitle.intro; These functions allow you to access MySQL database servers. More information about MySQL can be found at &url.mysql;. Documentation for MySQL can be found at &url.mysql.docs;.

&reftitle.required; In order to have these functions available, you must compile PHP with MySQL support.

&reftitle.install; By using the --with-mysql configuration option you enable PHP to access MySQL databases. If you use this option without specifying the path to MySQL, PHP will use the built-in MySQL client libraries. With PHP4 MySQL support is always enabled; if you don't specify the configure option, the bundled libraries are used. Users who run other applications that use MySQL (for example, running PHP 3 and PHP 4 as concurrent apache modules, or auth-mysql) should always specify the path to MySQL: --with-mysql=/path/to/mysql. This will force PHP to use the client libraries installed by MySQL, avoiding any conflicts. Crashes and startup problems of PHP may be encountered when loading this extension in conjunction with the recode extension. See the recode extension for more information.

&reftitle.resources; There are two resource types used in the MySQL module. The first one is the link identifier for a database connection, the second a resource which holds the result of a query.

&reftitle.examples; This simple example shows how to connect, execute a query, print resulting rows and disconnect from a MySQL database. \n"; while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) { print "\t\n"; foreach ($line as $col_value) { print "\t\t$col_value\n"; } print "\t\n"; } print "\n"; /* Free resultset */ mysql_free_result($result); /* Closing connection */ mysql_close($link); ?> ]]>
