Hi, I am working on a script for my members, what it does is allow the user to input an IP/Port of a game server into their profile, it works great but if the IP is no reachable or the member entered the wrong IP/Port it cause the page never to load, I put an error
"error: Either the server is offline or the query timed out."
any ideas how i get the script to quit and show the error if the IP is no reachable?
I left the mysql query out and some of the html to shorten the code a bit.
$ip = "209.191.132.41";
$port = "27015";
$mapdir = '../images/mappics/';

if (!$fp) {
echo "error: Either the server is offline or the query timed out.<br>\n";
} else {
fwrite($fp,"ÿÿÿÿdetails\x00");

fclose($fp);
