Codeigniter 4 Overview

Codeigniter 4 that is going to release after few month and Guys i am happy to talk about it . A lot of people were feeling that codeigniter will not survive more time because the lack of update. But it is true that codeigniter is still alive and coming with version 4. CI 4 has a lot of new features like command line interface and better exception handler etc.
Codeigniter has a large community of lovers and this is a big news for those who love it.
A large number of dedicated programmers worked to make a new version of codeignier and finally they will announce the release of stable codeigniter 4.

Why Need Codeigniter 4 ?

Actually when we compare codeigniter with the big and advance frameworks like Laravel and Symfony, codeigniter considered a backward type framework.
So if codeigniter compared with laravel it has small chances to score with developers because other frameworks has better functionality and coding style.
Old versions of codeigniter uses older versions of php and after the release of php 7, it is necessary to use the newer feature of php.
Laravel has released many newer versions like Laravel 5.2, Laravel 5.3, Laravel 5.4 and now Laravel 5.5
