Building web applications using Codeigniter (Installing Codeigniter)

Codeigniter is a powerful PHP framework which can be simply used to create full featured web applications.   This framework is based on the MVC Architecture. Here I am using Netbeans IDE as the editor. 

MVC Architecture

MVC or Model View Controller Architecture is a well known software designing pattern in creating web applications.One of the main advantage or a purpose of using MVC is to seperate business logic and the application data from the presentation layer. Model is the one who carries business logic and the application data. It handles data processing. Controller works as the mediator and converts input as commands for the model or the view. View is the interface shown to the user simply view is the presentation. Codeigniter is using this MVC architecture in it.
