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.
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
}
?>
