PublicMe is a class that gathers all the public user information that comes bundled with a single HTTP request.
To start using the class, just clone it from the includes folder and add it to your PHP file.
require 'class.publicme.php';
And then initialize it
$user = new PublicMe();

echo "User's Operating System: $user->os";
