Getting map size and seed in this PHP code?

How I can get map size and seed in this PHP code?

Thanks!!

Code:

$socket = @fsockopen("udp://".$ip, $queryport , $errno, $errstr, 1);
stream_set_timeout($socket, 1);
stream_set_blocking($socket, TRUE);
fwrite($socket, "\xFF\xFF\xFF\xFF\x54Source Engine Query\x00");
$response = fread($socket, 4096);
@fclose($socket);$packet = explode("\x00", substr($response, 6), 5);
$server = array();$server['name'] = $packet[0]; // Server Name
$server['map'] = $packet[1]; // Server Map (Procedural, Hapis, Craggy or Savas)
$server['game'] = $packet[2]; // Game name
$server['description'] = $packet[3]; // Description
$inner = $packet[4];
$server['players'] = ord(substr($inner, 2, 1)); // Players online
$server['playersmax'] = ord(substr($inner, 3, 1)); // Max Players
$server['vac'] = ord(substr($inner, 8, 1)); // Server secure

 

Code:

var_dump($response);

Does the response even contain the seed and size?

 

At the moment, you can't with query, but with rcon, you can. Just send "server.worldsize" to your rust server over RCON and the server will output something like "

Code:

[1/21/2016 10:30:41 PM] server.worldsize: "5000"

Then you only need to use a regex to only keep "5000" (in my case)

 

I feel like rust.io gets server seeds and map size without them running its plugin. And if that's the case there has to be a way outside of rcon.
