Yes, and in even larger scale applications it can become even more
useful. I have a web framework I'm working on, it's about 9,500 lines of
code now with hundreds of functions/classes. Every function/method has
to specify global for my 3 universal variables which contain large
arrays of configuration information. With this, I can say "superglobal
$mod, $sec, $cfg" in my root include file, and not worry about it again.
class Config {
const FOO = "Bar";
}
function oink() {
if (Config::FOO == 'Bar') {
echo "OINK";
}
}
etc.
IMO, you really don't need more superglobals.
