imap_ping — Check if the IMAP stream is still active

Descrição

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.

Parâmetros

imap_stream: Um stream IMAP retornado por imap_open().

Valor Retornado

Returns TRUE if the stream is still alive, FALSE otherwise.
