imap_ping

(PHP 4, PHP 5)

imap_pingCheck if the IMAP stream is still active

Описание

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.

Список параметров

imap_stream

Поток IMAP, полученный из imap_open().

Возвращаемые значения

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

This is a great solution for a webmail class if you want to make sure that a user is still logged in. Example:

<?php
if(!(imap_ping($stream)) {
die(
"The user is no longer logged in.");
?>
