In order to have these functions available, you must compile PHP with

MySQL support.

By using the <option role="configure">--with-mysql</option> 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: <option
|
|
role="configure">--with-mysql=/path/to/mysql</option>. This will force
|
|
PHP to use the client libraries installed by MySQL, avoiding any
|
|
conflicts.
