Yii is an amazing web application programming framework. It’s actually what I used to build Wordner a few years back. Yii is fast and powerful. It uses the Model-View-Controller (MVC) methodology. And, because it leverages PHP and MySQL, it can run on nearly any server.
For the past several years, the team who built Yii has been working to overhaul of the original framework. Yii 2 brings some significant enhancements to the framework, including support for namespaces, improved view echoing, and updates to widgets and themes.
