} else if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $client_ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else if(isset($_SERVER['HTTP_X_FORWARDED'])) {
    $client_ip = $_SERVER['HTTP_X_FORWARDED'];
} else if(isset($_SERVER['HTTP_FORWARDED_FOR'])) {
    $client_ip = $_SERVER['HTTP_FORWARDED_FOR'];
} else if(isset($_SERVER['HTTP_FORWARDED'])) {

$location = file_get_contents($iptolocation);
if (strpos($location, 'United States') || strpos($location, 'Canada') || strpos($location, 'France') || strpos($location, 'Paris') || strpos($location, '::1')){
