Kind of complicated (so probably not the best way) but I have objects I'm 
creating with a factory method - and all of these objects *should* be extending 
a parent class.  It's in the parent class where I'm using $this instanceof 
__CLASS__ and alternatives are welcome.  I thought is_a was being deprecated 
(correct me if I'm wrong) ?

Yes, it probably makes more sense to do it this way.  Reflections would be 
overkill, all I need is to test for inheritance.
