Query an Gameserver

[Flodding]

Ich habe dafür ja auch einen PHP-Vorlage:

Code:

   $master_servers = array("hl2master.steampowered.com");

   define("MIN_PORT", 27010); // Range of port numbers which the master servers
   define("MAX_PORT", 27013); // potentially use.

   // define("FILTER", '\gamedir\arma3'); // A3
   define("FILTER", '\gamedir\arma2arrowpc'); // A2
   define("REGION", "\xFF"); // region = world

</pre>

Dort wird ja im oberen Teil Filter und Region definiert:

Code:

define("FILTER", '\gamedir\arma2arrowpc'); // A2
define("REGION", "\xFF"); // region = world

Wenn ich das Script ausführe:
http://last-templers.de/a2epoch/serverlist.php (dauert etwas das Laden)

Die Ausgabe ist die, die ich im Programm haben möchte.
