Is $admin a global variable? I thought that it can be global only
after "global $admin;"-line in the code. Am I wrong? Any variable
which is given to the php-script via the address line will
automatically become global (if register_global is "on")?

I think I have some problems with the terminology. The above example I
would describe as follow. We have assign to a "normal" variable
($registered_global), a value taken from a session variable
($_SESSION). But you replace "normal" by "global" and "assignment" by
the "registration". Do you consider any "assignment" as the
"registration" or only those "assignment" is a "registration" in which
the value was taken from the $_SESSION?
