imap_ping — Check if the IMAP stream is still active
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.
| Versione | Descrizione |
|---|---|
| 8.1.0 |
The imap parameter expects an IMAP\Connection
instance now; previously, a valid imap resource was expected.

<?php
$imap = imap_open("{imap.example.org}", "mailadmin", "password");

// do some stuff to reconnect
}
