I want to set a flag those mail i had seen. Mean is there any alias function in zendframework those working like

<?php
$mbox = imap_open("{imap.example.org:143}", "username", "password")
or die("can't connect: " . imap_last_error());

$status = imap_setflag_full($mbox, "2,5", "\\Seen \\Flagged");

echo gettype($status) . "\n";
echo $status . "\n";

imap_close($mbox);
