The documentation says that you don't *need* to declare $_SESSION as global via the keyword
'global'. The truth is, you *must* *not* declare it as global. If you write something like
function blahr() {
global $_SESSION;
}
you turn of the black magic which is bound to this variable. You cannot register any additional
variables, neither you can change any existing session variable.
