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.”




Why should use CodeIgniter

• Very Simple

• Lightweight

• Excellent Documentation

• Large User Community

• Compatibility with standard hosting (PHP 5.2.4)




Server Requirements

• Apache Web Server 2.2

• PHP Version 5.3 or newer is recommended.

• MySQL (5.1+) via the mysql (deprecated), mysql and pdo driver.




CodeIgniter Architecture

• Running on LAMP Stack

• Model-View-Controller (MVC) development pattern




LAMP Stack



Linux Apache MySQL PHP


Model-View-Controller (MVC)• The Model represents your data structures. Typically your model classes will

contain functions that help you retrieve, insert, and update information in your database.

• The View is the information that is being presented to a user. A View will normally be a web page, but in CodeIgniter, a view can also be a page fragment like a header or footer. It can also be an RSS page, or any other type of “page”.

• The Controller serves as an intermediary between the Model, the View, and any other resources needed to process the HTTP request and generate a web page.
