mysql_close() closes a MySQL connection opened by mysql_connect() . The connection to close is specified with the connection argument. If no argument is specified, the last opened connection is closed.
Use of this function is not required. Connections opened by mysql_connect() close automatically on script exit.
mysql_close() cannot close the persistent connections that are opened by mysql_pconnect() . These connections last beyond the life of the script that opened them. PHP closes them as needed.
mysql_close () or die ("The last MySQL connection opened could not be closed.");
<?php $logger_connection = mysql_connect ('localhost', 'logger', '') or die ("Could not connect to database as user 'logger'."); $anon_connection = mysql_connect ('localhost', 'anon', '') or die ("Could not connect to database as user 'anon'."); if (mysql_close ($logger_connection)) echo "The connection for user 'logger' was closed."; else echo "The connection for user 'logger' could not be closed."; ?>
