(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)
imap_ping -- Check if the IMAP stream is still active
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.)
