CodeIgniter is an Application Development Framework – a toolkit – for people who build web sites using 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 a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications.
Our goal for CodeIgniter is maximum performance, capability, and flexibility in the smallest, lightest possible package.
To meet this goal we are committed to benchmarking, re-factoring, and simplifying at every step of the development process, rejecting anything that doesn’t further the stated objective.
From a technical and architectural standpoint, CodeIgniter was created with the following objectives:
CodeIgniter is a dynamically instantiated, loosely coupled system with high component singularity. It strives for simplicity, flexibility, and high performance in a small footprint package.
