AlliedModders - Did valve break query? (Need help with web codes)

I've noticed my web site can't get information from my servers anymore.
These are the codes and I have no idea why it won't work anymore.
PHP Code:

		
			
function query_source($ip, $port)

{

    $array = explode(":", $address);

    

    $server['status'] = 0;

    

    if (!$ip || !$port){ exit("EMPTY OR INVALID ADDRESS"); }

    

    $socket = @fsockopen("udp://{$ip}", $port, $errno, $errstr, 1);

    

    if (!$socket) { return $server; }

    

    stream_set_timeout($socket, 0, 500000);

    stream_set_blocking($socket, TRUE);

    fwrite($socket, "\xFF\xFF\xFF\xFF\x54Source Engine Query\x00");

    $packet = fread($socket, 4096);

    @fclose($socket);

    

    if (!$packet) { return $server; }

    

    $header                    = substr($packet, 0, 4);

    $response_type         = substr($packet, 4, 1);

    $network_version         = ord(substr($packet, 5, 1));



    $packet_array            = explode("\x00", substr($packet, 6), 5);

    $server['name']        = $packet_array[0];



    if ($response_type != "I")

    {    

        $server['map']            = "Query Blocked";

        $server['game']            = "unknown";

        $server['description']    = "Error: IP Query is blocked";

        @$app_id                = 0;

        $server['players']        = 0;

        $server['playersmax']    = 0;

        $server['bots']            = 0;

        $server['status']        = 0;

        $server['dedicated']    = 0;

        $server['os']            = 0;

        $server['password']        = 0;

        $server['vac']            = 0;

    }

    else

    {

        $server['map']            = $packet_array[1];

        $server['game']            = $packet_array[2];

        $server['description']    = $packet_array[3];

        $packet                    = $packet_array[4];

        @$app_id                = array_pop(unpack("S", substr($packet, 0, 2)));

        $server['players']        = ord(substr($packet, 2, 1));

        $server['playersmax']    = ord(substr($packet, 3, 1));

        $server['bots']            = ord(substr($packet, 4, 1));

        $server['status']        = 1;

        $server['dedicated']    = substr($packet, 5, 1);

        $server['os']            = substr($packet, 6, 1);

        $server['password']        = ord(substr($packet, 7, 1));

        $server['vac']            = ord(substr($packet, 8, 1));

    }



    

    return $server;

}
Can anyone help me fix it?
