keep form values

[drag0n]

Its beena while since Ive touched PHP.
I remember there was a Header function that you could use to keep all the user entered values in a form even those they pressed the back button. I remember it to go right after a session_start() function.
Anybody have any idea what this function is??? If there isnt such a function... are there any ways I can retain form values after a user presses the "Back" browser button?

Thanks

Putting your form values into the $_SESSION array will retain them on every page you have session_start() until you destroy the session.

How would I do that?

<?php
session_start();

$_SESSION['username'] = 'test_user';

echo "hello there ".$_SESSION['username'].", how are you today?";

that should print out:

hello there test_user, how are you today?
