It applies, to a degree. If you directly reference $GLOBALS anywhere in your function, you can also reference it indirectly. If you don't, however, indirect reference won't work. E.g., function foo() {

        $foo = "GLOBALS";
        print $$foo["bar"];             // won't work

} function foo() {

        $GLOBALS;
        $foo = "GLOBALS";
        print $$foo["bar"];             // will work

} That's a side effect of implementation, though, so I think it's best to say that indirect reference to $GLOBALS is not supported.

Yes, I also think we should document that indirect references to $GLOBALS shouldn't be used. It might change. Andi
