PHP-Handbuch: Closes a persistent database connection

Beschreibung

bool db2_pclose ( resource $resource )

This function closes a DB2 client connection created with db2_pconnect and returns the corresponding resources to the database server.

Hinweis:
This function is only available on i5/OS in response to i5/OS system administration requests.

If you have a persistent DB2 client connection created with db2_pconnect, you may use this function to close the connection. To avoid substantial connection performance penalties, this function should only be used in rare cases when the persistent connection has become unresponsive or the persistent connection will not be needed for a long period of time.

Parameter-Liste

connection: Specifies an active DB2 client connection.

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.

Beispiele

Beispiel #1 Closing a persistent connection

The following example demonstrates a successful attempt to close a connection to an IBM DB2 i5/OS database.


<?php
$conn = db2_pconnect('', '', '');
$rc = db2_pclose($conn);
if ($rc) {
    echo "Connection was successfully closed.";
}
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

Connection was successfully closed.
