imap_ping

(PHP 3, PHP 4, PHP 5)

imap_ping -- Check 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

An IMAP stream returned by 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.");
?>
