Code:

<? function sniff( $portnumber ) { $REMOTE_ADDR="localhost"; $sock = fsockopen("$REMOTE_ADDR", $portnumber, $errno, $errstr, 80); if (!$sock) { if ($errno == 60) { echo "Timeout"; } else { echo "Closed $errno"; } } else { echo "<font color=#ff3300>Open</font>"; fclose($sock); $sock</p>"; } } ?> <? sniff(22); ?>

Why do you keep posting then deleting your posts? Anyway most of the changes you made are no change. I don't think adding the quotes is going to make a difference because the code worked fine without them when it wasn't in its own function. Nope, just tested, no change.
