As far as I know,
it's not true you can't use session variables if register_globals is off,
the difference is that you must acces session variables using

ALWAYS CALL session_start() BEFORE TRYING TO USE THE $_SESSION SUPERGLOBAL!

also I don't quite see the connection with register_globals, but anyway
var sent by POST/GET can be found in the $_POST and $_GET superglobal vars


$_SESSION['variablename'], that's is an assurance that a session variable is a REAL session variable, and that it is not set using for example a faked form.

hope this is a correct answer and it helps you,

Hi all.

I taught myself PHP before the frenzy over register_globals.
After a reasonable break from the language, I'm back for more.

I'm building a site where I'll be holding a lot of variables in memory for each session. How do I do that? Apparently I can't use session_register() if register_globals is turned off. I've read a little about the consequences of writing bad scripts with register_globals on ... I'm fine with this explanation. I agree that I don't want people injecting variables into my session. What I want is for ME to be able to set variables and remember them throughout the session. How do I do that?
