PHP 忒聊 綴豖 ヶ輛 imap_ping (PHP 3, PHP 4) Description 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.) 綴豖 れ萸 ヶ輛 imap_open 奻珨撰 imap_qprint
