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.
CSS Stacker and Compressor is a PHP class that can be used to compact several CSS files into a single file. It can take several CSS files and generate a single file by concatenating all files after having stripped any white-space. The class can serve the resulting CSS file as the current script output. The CSS may be compressed with GZIP. If the original files were not modified, the class may return HTTP status 304 to make the browser use a cached version and prevent serving a file that was not changed.
