# mysql_close

(PHP 3, PHP 4 )

mysql_close -- Close MySQL connection

## Description

bool mysql_close ( [resource link_identifier])

Returns `TRUE` on success or `FALSE` on failure.

mysql_close() closes the connection to the MySQL server that's associated with the specified link identifier. If `link_identifier` isn't specified, the last opened link is used.

Using mysql_close() isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution. See also freeing resources.

> Note: mysql_close() will not close persistent links created by mysql_pconnect().

Example 1. MySQL close example
    <?php
        $link = mysql_connect("localhost", "mysql_user", "mysql_password")
            or exit("Could not connect");
        print ("Connected successfully");
        mysql_close($link);
    ?>
