SYNOPSIS
       Warning

	      This  extension  is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
	      be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

		     omysqli_close(3)

		     oPDO: Assign the value of
		       NULL to the PDO object

       bool mysql_close ([resource  $link_identifier = NULL])

DESCRIPTION
       mysql_close(3) 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(3) isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
       See also freeing resources.

	      o $
		link_identifier -The MySQL connection. If the link identifier is not specified,  the  last  link  opened  by  mysql_connect(3)	is
		assumed. If no connection is found or established, an E_WARNING level error is generated.

	Returns TRUE on success or FALSE on failure.
