[SOLVED] Need some help, need to redirect php page if http_host is called via IP.

[Cytranic]

I have this code but it does not seem to work. I did not create this, but maybe someone here can help.

 

The goal is I need the script redirect to another page if it detects the HTTP_HOST is an IP address rather then a HostName. I get errors with my below code saying delimiter cannot be alphanumeric, but if I replace \b with = it still wont work.. Any ideas?

 

$ip = $_SERVER["HTTP_HOST"];
$pattern = "\b(25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.(25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.(25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.(25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\b";

if (preg_match($pattern, $ip)) {
header("location: http://www.domain.com");
exit();
}

Try this pattern and see if that works better for ya.

 

$pattern = '/^((1?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(1?\d{1,2}|2[0-4]\d|25[0-5]){1}$/';
