@NogDogOct 26.2006 — #If you're talking about a service on the web host, you can look at the [url=http://www.php.net/com]COM/.NET Functions[/url] and/or the [url=http://www.php.net/manual/en/ref.sockets.php]Socket Functions[/url].
If you're talking about something on the client side, then probably not (since PHP is run on the server side).
