What is Codeigniter

CodeIgniter is a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications. CodeIgniter was created by EllisLab and is now a project of the British Columbia Institute of Technology

For building a web application you spend a lot of time writing the same code again and again. Frameworks provide you with a starting block and minimize the amount of code needed to build a website.

CodeIgniter is a PHP driven framework but it’s not a PHP substitute. Diving into CodeIgniter doesn’t mean you are leaving PHP behind. PHP is a server-side scripting language for building dynamic web-based applications.

CodeIgniter contains libraries, a simple interface and a logical structure to access these libraries, plug-ins, helpers and some other resources which solve the complex functions of PHP more easily maintaining high performance.  

It simplifies the PHP code and brings out a fully interactive, dynamic website in a much shorter time. It supports the PHP version of 5.2.6 or newer and MySQL version 4.1 or newer.
