ZF and CI are horrible examples of coding practices. They are extreme examples of "make a class for everything because you can". ZF file and directory structure is at odds with PHP 6's namespaces, in fact it will probably have to be completely thrown away to make way for a ZF 2.

CI doesn't even have the base class of any "controller" defined anywhere for you to read. It is created on the fly every request. This guy is a noob and doesn't understand what good programming is.
