(PHP 4, PHP 5)

imap_pingCheck if the IMAP stream is still active

Description

bool imap_ping ( resource $imap_stream )

Parameters

imap_stream

An IMAP stream returned by imap_open().

Return Values

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

Examples

Example #1 imap_ping() Example

<?php

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

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

?>
