CodeIgniter2.1.0

CodeIgniter is a powerful PHP framework with a very small footprint, built for PHP coders who need a simple and elegant toolkit to create full-featured web applications. CodeIgniter provides a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries.

CodeIgniter is written to be compatible with PHP 4. It will run on PHP 5 but does not take advantage of any native features that are only available in that version.
