CodeIgniter is a PHP web application framework that focuses on minimizing code for common tasks. It was created in response to documentation issues and complexity in other frameworks. CodeIgniter sees popularity due to its lightweight nature, active record database support, and ease of use through features like form validation and file uploading. It follows an MVC architecture and has a large user community. While flexible and customizable, it lacks some object orientation and has irregular release cycles.
