I'm no good at writing sample / filler text, so go write something yourself.
Wondering how to use it? We'll show you!
First, make sure you include the referrer.php class into your script.
//Instantiate a Referrer object
$referrer = new Referrer([string] cookie_name, [boolean] enable_encryption, [boolean] enable_verification);
//Make sure to run this method on EVERY page, in order to acurately verify the referrer.
$referrer->check_referrer();
//Finally, to retrieve the original referrer use
$referrer->retrieve_referrer();
//to decrypt and verify the cookies if necessary.
//Returns the URL of the referrer, or false if none was found.That's it! There's really nothing to it.
