yeah that's right; add in one more line and the reason why is apparent..
Well I think "is apparent" is a bit strong considering e.g. C++ syntax where syntax is equally valid but the semantics are different.
So to answer the OPs question, yes this is different in PHP compared to other languages. I think this is due to the fact that classes are kinda bolted on in PHP and there isn't really such a thing as "being in a class" in terms of scoping. $this is allows the class scope to be kind of emulated inside a functional scope.
I could be wrong here, but that's my understanding of it.
