CodeIgniter User Guide Version 2.2.6


CodeIgniter was originally developed by Rick Ellis (CEO of EllisLab, Inc.). The framework was written for performance in the real world, with many of the class libraries, helpers, and sub-systems borrowed from the code-base of ExpressionEngine.

It was, for years, developed and maintained by EllisLab, the ExpressionEngine Development Team and a group of community members called the Reactor Team.

In 2014, CodeIgniter was acquired by the British Columbia Institute of Technology and was then officially announced as a community-maintaned project.

Bleeding edge development is spearheaded by the handpicked contributors of the Reactor Team.

A hat tip goes to Ruby on Rails for inspiring us to create a PHP framework, and for bringing frameworks into the general consciousness of the web community.
