$foo is less characters than $_POST['foo'], so yes it is easier to type. I didn't say it was right, I just said it made it easier. Anytime you see id= in a url or name= in a form just throw a $ sign in front of it and you're in business. I guarantee you a starting user will get that faster than $_GET and $_POST. Someone just coming at this isn't going to understand the difference between request types or the fact that a form can even have both of them in the method. :) > > of course if you know absolutely nothing about php it make's it easier - but > in the long run (same the 5 or 10 minutes it takes to read up on request > superglobals) > it's an accident waiting to happen.
