Build A CodeIgniter PHP App - Part 1

description
We will be building a PHP Codeigniter blog application with CRUD functionality. In this video we will install Codeigniter, setup a Pages controller, add views and routing. Code For This Application - https://github.com/bradtraversy/ciblog 10 project PHP Frameworks course - https://www.eduonix.com/affiliates/id/16-10371 PHP 7 Developers Guide - https://www.eduonix.com/affiliates/id/16-10399
