PHP Force www Subdomain

Sometimes you do not want users to access your domain without the www. If you want to force and redirect to here is a simple way to do it:

if ((strpos($_SERVER['HTTP_HOST'],'www.')===false)) { header('Location:'); exit(); }

You would use this especially for SEO where you did not want to be indexed both ways. Also depending on your framework and the way urls are read, you may need to stay consistent. Just place this code at the top of your page and you are good to go.
