imap_ping

(PHP 3, PHP 4, PHP 5)

imap_ping -- Check if the IMAP stream is still active

Description

bool imap_ping ( resource imap_stream )

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

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.

例子 1. imap_ping() Example

<?php

$imap
= imap_open("{your.imap.host}", "mailadmin", "password");

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

?>
