I think there's a setting in php.ini that automatically imports $_POST, $_GET, $_SESSION, and $_COOKIE variables into the local variable space - sort of like automatically calling extract($_POST), etc at the head of every file. I can't remember what the setting is though.
If you find it, you can either change php.ini, or call ini_set() to change that setting.

Or, if you are on a shared host and/or don't want to mess with php.ini settings, use variable names that are different from $_SESSION index names. But pickle is right, there is some such setting, and it can make you think you have gone nutzoid if you don't know about it.

register_globals directive

I hear will be removed in PHP6 (finally!)
