This document discusses PHP and the MVC framework. It begins with a brief introduction to MVC and its history. MVC originated in Smalltalk-80 in the 1970s and has since been used in many GUI frameworks. MVC is well-suited for web development and there are over 17 PHP MVC frameworks currently. Common traits of MVC frameworks include an index.php file that routes requests, separate directories for controllers, models, and views, and additional helpers and plugins. Using an MVC framework provides benefits like good architecture, easy code maintenance, and the ability to easily extend the application. Many large sites now use PHP MVC frameworks.
