Zikula

Zikula is a web development framework written in PHP that you can use to build robust and secure websites and web apps that have a strong focus on interactivity and collaboration. This framework is entirely modular, object-oriented, and based on Symfony, which means that’s highly stable and extensible.

Zikula is Free Open Source Software (FOSS). It allows you to build simple one-page websites to individual web applications utilising different types of extensions for making your project to something special.
