Close MySQL connection


mysql_close

(PHP 4, PHP 5)

mysql_closeClose MySQL connection

Description

bool mysql_close ([ resource $link_identifier = NULL ] )

mysql_close() closes the non-persistent 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.

Parameters

link_identifier

The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no connection is found or established, an E_WARNING level error is generated.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 mysql_close() example

<?php
$link 
mysql_connect('localhost''mysql_user''mysql_password');
if (!
$link) {
    die(
'Could not connect: ' mysql_error());
}
echo 
'Connected successfully';
mysql_close($link);
?>

The above example will output:

 Connected successfully 

Notes

Note:

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