I'm setting up an Online Game Private Server, and I got a problem in opening the launcher.exe then I checked on its WEB files which is the fetch.php. What will be the problem in line 5?

<?php
// impediment url
$url = $_SERVER['QUERY_STRING'];

list($app, $ver) = explode("&", $url);
if(!is_numeric($app) || !is_numeric($ver)) {
echo "Error";
exit();
}
if($app != round($app) || $ver != round($ver)) {
echo "Error";
exit();
}
?>
