}
}
?>
and i have index.php file

You should be using the index.php file that came with CodeIgniter.

You do not have a constructor method in your Blog class. For PHP4, the constructor's method name would be Blog as shown below. For PHP5, the constructor's method name would be __construct(). The constructor method of the parent class must be called in the constructor. The Index() function includes the private portion of the constructor which is only used within that class. By comparison, the code in the constructor (i.e., the Blog or __construct method) can be inheirited by any controller subclassed (extended) from the Blog class.

Code:
&lt;?php 

class Blog extends Controller 

{

    function Blog()

    {

        parent::Controller();    

    }

    function index() 

    { 

        echo 'Hello World!'; 

    } 

}
