imap_ping

(PHP3 , PHP4 )

imap_ping --  Prüft, ob die aktuelle Verbindung noch verfügbar ist

Beschreibung

int imap_ping (int imap_stream)

Liefert true, wenn die aktuelle Verbindung noch verfügbar ist, sonst false.

Die imap_ping() Funktion schickt ein Ping-Signal an den Mailserver und prüft so die Verfügbarkeit der Verbindung. Auf diese Weise kann die Verbindung zu einem Server aufrechterhalten werden, der Verbindungen nach einer gewissen Zeit ohne Aktivität automatisch beendet (da PHP-Scripte i.A. nicht sehr lange laufen, kann ich mir kaum vorstellen, das jemand diese Funktion wirklich benötigt).
