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.
