Swiftlet is a lightweight Web application framework written in PHP. It enables you to quickly deploy Web sites that are fast and secure. Swiftlet is extensible, flexible, and doesn't get in your way. Swiftlet requires zero configuration and has few conventions to which you must adhere. Swiftlet has all the features you would expect from a modern Web application framework. It implements the Model-View-Controller (MVC) architecture pattern to separate logic from design and takes advantage of the Object-Oriented Programming (OOP) capabilities of PHP 5.
PWF (PHP Web Framework) is an extremely lightweight but powerful PHP Web framework that uses the MVC pattern and object oriented programming. It makes it easier to write applications with clean code and clear architecture, and has a small learning curve. It doesn’t need installation and works in most environments. The controller used for each request is selected through simple but effective rules, and the method by the type of the request. It provides database abstraction with data-object mapping.
