The variables are already parsed at the beginning. All variables in the
scope the include is called in (so global scope if called in global, the
scope of a function if called in that) are available to the included
script.

Furthermore, the $_GET ($_POST/$_SERVER/$_SESSION/$_REQUEST/$_ENV) are
'superglobals', which means you can access them directly from any point in
the script(s), they're always in scope.
