CodeIgniter First Example

A controller is set up to handle static pages. A controller is a class that simplifies the work in CodeIgniter.

In a CodeIgniter framework URL a basic pattern is followed.

In the following URL,

http://abc.com/book/novel/

Here, 'book' is the controller class or you can say this is the controller name.

'novel' is the method that is called. It extends to CI_Controller to inherit the controller properties.
