I was just wondering if there is a certain way that you are definitely supposed to use variables passed to a script from a form. I usually just call the variable using the name of the form field such as $email.
But I noticed that most people seem to use either $_POST['email']
My question is, does it actually make a difference? Is there a good reason why I would want to use one of the longer versions rather than the way I do it? As always, thanks for the input.
