HLTV controled by php

[4JOKE]

I'm not good at working with sockets, but I search some websites and try to create php script, which will send commands to hltv(half life 1) via php. But something seems to be wrong because hltv on my pc doesn't do anything when I send some command.

So here is my code:

PHP Code:

<?php 

//get challenge from HLTV

$cmd = "\xFF\xFF\xFF\xFF"."challenge rcon"."\n";

$getchallenge = getServerData($cmd, '89.173.135.189', '27020');

$getchallenge = substr($getchallenge, 5);

$getchallenge = trim($getchallenge);



HalfLife_Rcon('myHLTVIPadress', 'myHLTVport', 'myHLTVrcon', 'record test.dem', $getchallenge);



function GetServerData($command, $ip, $port)

{



    $data = '';

    if (!$server_connection = fsockopen('udp://'.$ip, $port))

        return false;



    socket_set_blocking($server_connection, 1);

    # Time out after 5 seconds

    socket_set_timeout($server_connection, 5);

    fwrite($server_connection, $command, strlen($command));    



    # This must time out first to make sure the right arguement is returned

    # The above timeout is just to make sure it doesn't go over 4 seconds

    $timeout = microtime();

    $timeout += 4;

    $i = 0;

    $packets = 0;

    do

    {

        do

        {

            $data .= fread($server_connection, 8192);

            if (microtime() > $timeout)

            {

                # Connection timed out

                fclose($server_connection);

                return false;

            }

            $data_status = socket_get_status($server_connection);

        }

        while ($data_status['unread_bytes']);

        if (GetInt8($data, $tmp = 0) == 254)

        {

            # We have a split packet!

            $tmp = 0;

            # Get rid of the crap at the start

            GetInt32($data, $tmp);

            GetInt32($data, $tmp);

            $split_packet = str_pad(DecBin(GetInt8($data, $tmp)), 8, 0, STR_PAD_LEFT);

            $packet_num = bindec(substr($split_packet, 0, 4));

            $packets = bindec(substr($split_packet, 4));

            $data = substr($data, $tmp);

            $packet_data[$packet_num] = $data;

            $data = '';

        }

        elseif ($packets > 0)

        {

            # Silly rcon problems

            $tmp = 5;

            # Get rid of the crap at the start

            $data = substr($data, $tmp);

            $packet_data[] = $data;        

        }

        

        $i++;

    }

    while ($i < $packets);

    fclose($server_connection);



    if ($packets > 1)

    {

        ksort($packet_data);

        $data = implode('', $packet_data);;

    }

    if (strlen($data) == 0)

    {

        # We got no data?! Something must have gone wrong

        return false;

    }



    return $data;

};



function HalfLife_Rcon ($ip, $port, $rcon, $command, $challenge)

{



    $cmd = "\xFF\xFF\xFF\xFFrcon ".$challenge." ".$rcon." ".$command;



    if (!$serverdata = getServerData($cmd, $ip, $port))

        return false;



    $serverdata = substr($serverdata, 5);

    $serverdata = trim($serverdata);



    return $serverdata;

};



function getInt8($pos,$string) {

    if (strlen($string) > $pos) {

        $packarray = unpack('Ci',substr($string,$pos,1));

        return $packarray["i"];

    } else {

        return 0;

    }
