Server Status

Code:

<?PHP
function serverstatus($host, $port) {
$sock = @fsockopen($host, $port, &$num, &$error, 2);
if ($sock) {
if (getservbyport($port,"tcp")!=null) {
$serv = getservbyport($port,"tcp");
} else {
$serv = "Unknown";
}
echo "<center>Server : <span style='color:green'>Online</span></center>";
fclose($sock);
unset($sock);
}else{
echo "<center>Server : <span style='color:red'>Offline</span></center>";
unset($sock);
}
}

//Ports To Scan
serverstatus("68.100.166.101", 4000);

//Dark Dragon
?>

this is a script that tells if a server is on or off
