A couple of things come to mind. 1 - If you create a subclass and were overriding num_rows(), the subclass would have to also override NumRows(). Twice as much work. 2 - You could use __call() and __callStatic() magic methods, but you'd have limited options for documentation then (assuming you use docblocks. Personally, I would recommend using 1 naming convention and sticking with it.
