What level of error reporting did you use - E_ALL? I believe using an index 
that does not exist generates an e-notice warning.

I also often use false as a return value. If a valid return isn't an array, 
just remember that null, and the # 0, also evaluate as false. The safest bet 
is to use === to match the type.
