Description
int
imap_ping ( int imap_stream)
Returns TRUE if the stream is still alive, FALSE otherwise.
imap_ping() function pings the stream to see
it is 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.
(As PHP scripts do not tend to run that long, i can hardly
imagine that this function will be usefull to anyone.)
