i gave $tanim in function use:

function rcon_komut($komut, $rcon_pass, $ip, $port)
{
        $msg = "ÿÿÿÿchallenge rcon";
        $fp = fsockopen("udp://".$ip,$port, $errno, $errstr);
                
        stream_set_blocking($fp, 0);
                
        fputs($fp, $msg, strlen($msg));
        $response = fgets($fp, 1024);                           
        $challenge = substr($response, 19, strlen($response) - 20);
                
        $msg="ÿÿÿÿrcon".$challenge."\"".$rcon_pass."\"".$komut.chr(0);
        fputs($fp, $msg, strlen($msg));
                
        while (!feof($fp))
                $response .= fgets($fp, 32);

        fclose ($fp);
        $response = substr($response, 6, strlen($response)-6);
        return $response;
}

Well, can you give a script that has some possibility of working
properly? In the give script you have at least one variable which is not
set anywhere: $komut

It still hangs:

$fp = fsockopen("udp://".$ip,$port, $errno, $errstr);
stream_set_blocking($fp, 0);

Shouldn't you make the stream non-blocking? Try adding this after
fsockopen:

stream_set_blocking($fp, false);

Description:
------------
Using feof on UDP hangs. It should give true or false, in my example it
should give true but it hangs. I've tried many ways but it always hangs.

Reproduce code:
---------------
$msg = "ÿÿÿÿchallenge rcon";

$fp = fsockopen("udp://62.68.207.16",27015, $errno, $errstr);
fputs($fp, $msg, strlen($msg));
$response = fgets($fp, 1024);                           
$challenge = substr($response, 19, strlen($response) - 20);
                
$msg = "ÿÿÿÿrcon ".$challenge." \"123456\" ".$komut.chr(0);
fputs($fp, $msg, strlen($msg));

echo feof($fp) ? 'true':'false';
                
$response .= fgets($fp, 32);

fclose ($fp);

Expected result:
----------------
true

Actual result:
--------------
hangs
