需要有关php框架的帮助（codeigniter）

Question

I know php well. But I am a very new learner of php framework . I am learning codeigniter 2.0.3. I am trying to develop a simple hello world application.

I have tried this code..

class Hello extends Controller{
  function Hello(){
    parent::Controller();
  }
  function you(){
    $this->load->view("you_view");
  }

}

But unfortunately I am receiving this error ...

Fatal error: Class 'Controller' not found in C:\\wamp\\www\\CodeIgniter\\application\\controllers\\hello_world.php on line 7

Answer 1

Controller应为CI_Controller ，如下所示：

class Hello extends CI_Controller{

Answer 2

Should be:

class Hello extends CI_Controller{
  function __construct() {
    parent::__construct();
            /* use this only for setting default values, 
            loading helpers, models, ... */
    }
    function you() {
      $this->load->view("you_view");
    }
 }
