Question

So I’ve got a PHP-based site that’s running on Apache. The URL’s of the pages I’m talking about look like this:
http://www.example.com/?task=0&fw=FW_1W9AigHcAzgtjhBNc6W1QW
The long string for fw is randomly generated. Starting from ?fw=FW_1W..., it’s always 36 characters long. If someone adds anything to this, a major malfunction occurs and does some permanent damage (weird situation, I know…). What I’m looking to do is make my PHP script ignore everything after a certain number of characters in the URL. Or perhaps ignore everything after 25 characters for $fw? I barely understand programming but I feel like this should be possible… Much appreciated 🙂

What an odd setup… but sure you can:

$fwstring = substr($_GET['fw'],0,25);   //get 25 chars from index 0 of $_GET['fw']
