imap_pingCheck if the IMAP stream is still active

Descripción

imap_ping(IMAP\Connection $imap): bool

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.

Parámetros

imap

An IMAP\Connection instance.

Valores devueltos

Returns true if the stream is still alive, false otherwise.
