In the part 1, we give you the example of simple code right? Now you look these code, and you will se the function name is index(). The “index” function is always loaded by default if the second segment of the URI is empty. Another way to show your “Hello World” message would be like this example.com/index.php/blog/index/ .
The second segment of the URI determines which function in the controller gets called. Let’s try it. Codeigniter php frameworks would you to add new function to your controller. If you don’t have any idea to build something, you can follow this code to your controller.
<?php
class Blog extends CI_Controller {
                public function index(){
                                echo 'Hello World!';
                }
                public function comments(){
                                echo 'Look at this!';
                }
}
?>
