CodeIgniter is an open source web application framework for use in building dynamic web sites with PHP. "Its goal is to enable [developers] to develop projects much faster than...writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries." The first public version of CodeIgniter was released on February 28, 2006. The latest stable version 2.0.3 was released August 20, 2011. CodeIgniter is loosely based on the popular Model-View-Controller development pattern. While view and controller classes are a necessary part of development under CodeIgniter, models are optional. CodeIgniter is most often noted for its speed when compared to other PHP frameworks. In a critical take on PHP frameworks in general, PHP creator Rasmus Lerdorf spoke at frOSCon in August 2008, noting that he liked CodeIgniter "because it is faster, lighter and the least like a framework." A notable feature of the license is the requirement to indemnify the authors of the Software for any third-party claims, actions or suits arising from your use of the Software.
