CakePHP is an open-source web framework. It follows the model–view–controller (MVC) approach and is written in PHP, modeled after the concepts of Ruby on Rails, and distributed under the MIT License. CakePHP uses well-known software engineering concepts and software design patterns, such as convention over configuration, model–view–controller, active record, association data mapping, and front controller. CakePHP started in April 2005, when a Polish programmer Michal Tatarynowicz wrote a minimal version of a rapid application development framework in PHP, dubbing it Cake. He published the framework under the MIT license, and opened it up to the online community of developers. In December 2005, L. Masters and G. J. Woodworth founded the Cake Software Foundation to promote development related to CakePHP. Version 1.0 was released in May 2006.
