# mysql_close

mysql_close -- close MySQL connection

## Description

`int mysql_close`(int [link_identifier] );

Returns: true on success, false on error.

mysql_close() closes the link to a MySQL database that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.

> Note: This isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.

mysql_close() will not close persistent links generated by mysql_pconnect().

Example 1. MySQL close example

      2 <?php
      3     $link = mysql_connect ("kraemer", "marliesle", "secret") {
      4         or die ("Could not connect");
      5     }
      6     print ("Connected successfully");
      7     mysql_close ($link);
