Rcon query with PHP...need some help?

[Dekken]

well iam not that advanced scripter...so i took some stuff i found and combined it pretty much

PHP Code:

<form method="post" action="<?php $_SERVER['PHP_SELF'] ?>">

<input name="command" type="text"><br>
<input type="submit" value="QUERY RCON COMMAND">
</form>





<?php
$command = $_REQUEST['command'] ;

function getByte(&$string)
{
    $data = substr($string, 0, 1);
    $string = substr($string, 1);
    $data = unpack('Cvalue', $data);
    return $data['value'];
}

function getShortUnsigned(&$string)
{
    $data = substr($string, 0, 2);
    $string = substr($string, 2);
    $data = unpack('nvalue', $data);
    return $data['value'];
}

function getShortSigned(&$string)
{
    $data = substr($string, 0, 2);
    $string = substr($string, 2);
    $data = unpack('svalue', $data);
    return $data['value'];
}

function getLong(&$string)
{
    $data = substr($string, 0, 4);
    $string = substr($string, 4);
    $data = unpack('Vvalue', $data);
    return $data['value'];
}

function getFloat(&$string)
{
    $data = substr($string, 0, 4);
    $string = substr($string, 4);
    $array = unpack("fvalue", $data);
    return $array['value'];
}

function getString(&$string)
{
    $data = "";
    $byte = substr($string, 0, 1);
    $string = substr($string, 1);
    while (ord($byte) != "0")
    {
        $data .= $byte;
        $byte = substr($string, 0, 1);
        $string = substr($string, 1);
    }
    return $data;
}

function checkEmpty($variable)
{
    if($variable == NULL || $variable == '' || $variable == "" || $variable == " ")
    {
        $isempty = true;
    }
 
    else 
    {
            $isempty = false;
    }

return($isempty);
}

if(!CheckEmpty($command))
{

    define('PACKET_SIZE', '1400');
    define('SERVERQUERY_INFO', "\xFF\xFF\xFF\xFFTSource Engine Query");
    define ('REPLY_INFO', "\x49");
    define('SERVERQUERY_GETCHALLENGE', "\xFF\xFF\xFF\xFF\x57");
    define ('REPLY_GETCHALLENGE', "\x41");
    define('SERVERDATA_AUTH', 3) ;
    define ('SERVERDATA_EXECCOMMAND', 2) ;



    $_ip = '62.90.138.115' ; // server ip
    $_port = '27011'; // server port
    $_password = 'aj94ze' ; // your rcon password
    $s2 = '';
    $requestId = 1;



    $socket = fsockopen ('tcp://'.$_ip, $_port, $errno, $errstr, 30) ;
    $data = pack("VV", $requestId, SERVERDATA_AUTH).$_password.chr(0).$s2.chr(0);
    $data = pack("V",strlen($data)).$data;
    fwrite ($socket, $data, strlen($data)) ;

    $junk = fread ($socket, PACKET_SIZE) ;
    $string = fread ($socket, PACKET_SIZE) ;
    $size = getLong($string) ;
    $id = getLong ($string) ;



    if ($id == -1)
    {
        die ('Auth failed: bad password !') ;
    }



    $data = pack ("VV", $requestId, SERVERDATA_EXECCOMMAND).$command.chr(0).$s2.chr(0) ;
    $data = pack ("V", strlen ($data)).$data ;
    fwrite ($socket, $data, strlen($data)) ;
    $requestId++ ;



    $i = 0 ;
    $text = '' ;
    while ($string = fread($socket, 4))
    {
        $info[$i]['size'] = getLong($string) ;
        $string = fread($socket, $info[$i]['size']) ;
        $info[$i]['id'] = getLong ($string) ;
        $info[$i]['type'] = getLong ($string) ;
        $info[$i]['s1'] = getString ($string) ;
        $info[$i]['s2'] = getString ($string) ;
        $text .= $info[$i]['s1'] ;
        $i++ ;
    }


    $first= strpos ($text, '"', 12) ;
    $first++ ;
    $last = strpos ($text, '"', $first+2) ;
    print "Rcon Respone: " . substr($text, $first, $last-$first) ;

}
?>

the main two problems are.
everytime i execute long command lets say like "exec server.cfg" (which executes lots of commands in once)
it crashes the server.
other issue, the query is very slow
i write for example
map cp_badlands
takes it about 30second to change map...sometimes its instant
sometimes its slow like hell
also i added the CheckEmpty stuff...to stop the page from reloading for years first time you open it :X
anyone mind helping and improving this?

thanks =\


(probably posted on the wrong forum, so move it to the correct one please)

There are many written RCon classes already, you can find a few in the tutorials section of this forum too, it's really a waste of time to write it yourself.

well iam way more satisfied when i understand what the script does and able to add stuff to it :O
only thing i wonder is, what is the loop for?
i removed the loop, now it retrieves the Respond way quicker, Instantly.


well never mind
now i have other issue i wanna take care of.
everytime i get rcon respone..lets say i get it like this:

Code:

"sv_password" = "157" ( def. "" ) notify - Server password for entry into multiplayer games

its supposed to come out like this:

Code:

"sv_password" = "157" ( def. "" )
notify -
Server password for entry into multiplayer games

with spaces and what not
how can i detect spaces and add them manually? thx
