imap_ping

Check if the IMAP stream is still active

Description

bool imap_ping ( resource $imap_stream )

imap_ping pings the stream to see if it's still active. It may discover new mail; this is the preferred method for a periodic "new mail check" as well as a "keep alive" for servers which have inactivity timeout.

Parameters

imap_stream

An IMAP stream returned by imap_open.

Return Values

Returns TRUE if the stream is still alive, FALSE otherwise.

Examples

<?php

imap_open("{imap.example.org}""mailadmin""password");

// after some sleeping
if (!imap_ping($imap)) {
    
// do some stuff to reconnect
}

?>
