What is New In CodeIgniter 4.x

Code Igniter 4 Release Date

CodeIgniter is an open-source software rapid development web framework, for use in building dynamic web sites with PHP.

Codeigniter is a lightweight MVC architecture based PHP framework.

This is popular for its performance and zero configuration. Codeigniter has beautiful documentation. Since CI is the most flexible PHP MVC framework, people love to work on this.

CodeIgniter is loosely based on the popular model–view–controller (MVC) development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional.

CodeIgniter can be also modified to use the Hierarchical Model View Controller (HMVC) which allows the developers to maintain modular grouping of Controller, Models and View arranged in a sub-directory format.
