You think it'll make your code "messy" but to anyone else that has to
eventually read your code, it'll be a lot clearer to them. Also, when
you come back later to edit this code, you'll know exactly where
$_SESSION['varname'] came from, instead of having to wade through your
code and find the part where you say $varname = $_SESSION['varname'].
I don't understand why people are so afraid to just use the $_GET,
$_POST, etc arrays in their code and have to assign them to temp
variables. You're just wasting time and memory.

Well, $var will be "bar" at the end of each script, but only the first
example (with register globals on) will actually change the session
value. With register globals off, $_SESSION['var'] and $var are two
totally different variables.
Just get in the habit of using $_SESSION['varname'], you'll be better
off for it.
