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.
Version | Description |
---|---|
8.1.0 |
The imap parameter expects an IMAP\Connection
instance now; previously, a valid imap resource was expected.

// do some stuff to reconnect
