What is CodeIgniter?
CodeIgniter is an open-source framework for developing a dynamic web application with the use of PHP. It uses the MVC framework to develop the project, which is much faster than from the writing code to scratch. Also, it has a rich collection of libraries for connecting with the database and performing multiple operations like sending an email, validation, uploading of the files, deleting, and more. Furthermore, it is a lightweight framework whose main task is to reduce the complexity of the program and create a well-defined application.

History of CodeIgniter
Rick Ellis created the first beta 1.0 CodeIgniter framework at EllisLab on February 28, 2006. The CodeIgniter was taken from the Expression Engine, which is a collection of refracted class written for EllisLab’s flagship CMS (Content Management System). In July 2013, EllisLab announced that they did not have enough resources for developing the CodeIgniter framework, so they were finding a new owner to this framework
for developing. And in October 2014, EllisLab announced that the CodeIgniter would further, developed under the supervision of the British Columbia Institute of Technology.
