Yes, that's a lot different than your original question.
You can use is_a() as Marcin suggested. But what's to stop me from
creating my own class 'A'?
The real question is - why do you need this "feature"? It violates
several principles of OO.
OO principles include that you don't care WHAT the object is - all you
care about is its interface (functions). If you need to depend on a
specific class, you need to rethink your design.
