Valve updated the query protocol and the author of this script hasn't updated his files, so here is an updated version I put together. Just overwrite your cssource_class.php file with this code:
<?php
class cssource {
var $ip;
var $port;
var $timeout;
var $sock;
var $data;
var $output = array();
var $sortBy;
function cssource($ip, $port="", $timeout=200) {
$this->ip = $ip;
$this->port = (empty($port)) ? 27015 : $port;
$this->timeout = $timeout;
}
function get_challenge()
{
socket_set_timeout($this->sock, 2);
// get challenge number from server
fwrite($this->sock, "\xFF\xFF\xFF\xFF\x57");
$challenge = fread($this->sock, 4096);
$challenge = substr($challenge, 5, 4);
return $challenge;
}
function status() {
if(!$this->sock = @fsockopen("udp://".$this->ip, $this->port, $errno, $errstr, 30)) {
die("Could not connect to the socket.");
}
else {
$querys[] = "\xFF\xFF\xFF\xFFTSource Engine Query\x00";
$challenge = $this->get_challenge($this->sock);
$querys[] = "\xFF\xFF\xFF\xFF\x55" . $challenge;
$querys[] = "\xFF\xFF\xFF\xFF\x56" . $challenge;
$wait = 0;
foreach($querys AS $querystring) {
fwrite($this->sock, $querystring);
while($wait < $this->timeout) {
$string = fread($this->sock, 4096);
$wait += 10;
if(!empty($string)) {
$this->data[] = $string;
if(strlen($string) < 4096)
break;
}
}
}
@fclose($this->sock);
