PIMF (Php Is My Framework) is a micro framework for PHP that emphasises minimalism and simplicity. It is based on proven design patterns and a fast object relational mapping mechanism, and is designed to be easily updated without having to rewrite your projects. It includes mechanisms for easily coupling controllers to ExtJs and Dojo.
IrisMVC is an OOP PHP framework that developers can use as a strong and secure foundation on which to build various Web applications following the Model-View-Controller (MVC) pattern. It only provides the basic functionality developers need, without reinventing the wheel, so the learning curve is dramatically short and they should be able to start using it at full capacity in days. The goal is to allow developers to create Web sites faster without needing to learn a whole new PHP framework.
