GETting or POSTing a form

How do I determine whether I am GETting from a form (i.e. first time called) or being POSTed from a form(the user caused a submit)?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

there are 2 global arrays $_GET and $_POST

if you looking for some field name, let's say 'submit' you may check which of $_GET['submit'] or $_POST['submit'] is defined

You mean from the client side or the server side?
from the server side it's trivial, just check the $_SERVER['REQUEST_METHOD'] variable..
it should be either GET or POST
