CodeIgniter is a popular PHP web application development framework that allows developers to build full-featured, scalable, and secure web applications with ease. It is an open-source framework that follows the Model-View-Controller (MVC) architectural pattern, which separates the application logic from the presentation layer, making it easy to manage and maintain code.
CodeIgniter provides a simple and elegant toolkit for building web applications, including a database abstraction layer, a templating system, and a robust set of libraries for common tasks such as form validation, file uploading, and email management. It also has a lightweight footprint, making it ideal for shared hosting environments.
