CodeIgniter is an open source rapid development web application framework, for use in building dynamic web sites with PHP.
Its goal is to enable you to develop projects much faster than you could if you were 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.
CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.
CodeIgniter is loosely based on the popular Model-View-Controller development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional.
