OpenReviewScript is software for creating review Web sites. All you need is PHP hosting with a database. The simple installer gets you set up in minutes. A theme system lets you create or modify designs without needing to know any PHP. All themes are CSS/HTML based with a separate set of template files that control the content on each page. You have access to every single line of code; nothing is encrypted.
Lightweight MVC is a PHP implementation of the MVC design pattern. It is small and ideal for learners. There is no view loader, so all public methods and variables inside the controllers will be exposed to the views. It uses a library system to make it easy to move your codebase to and from other MVC implementations.
Automap is a fast map-based PHP autoloader. It resolves symbols using map files. These files are created offline by a program (included) which scans your script files and extracts their symbols. At runtime, map files are loaded by the main script and then used to resolve undefined symbols and load the corresponding PHP script files. An optional PECL extension is available to make it faster still.
