Only FalseClass and NilClass are false in Ruby, so if it can be an empty

Since the if/end is not the last expression in the function this will 
never be returned as a value. Use explicit return.

You might be better off rewriting from scratch than translating from 
PHP. You could start by documenting what the functions *do* ;)
