Codeigniter, php5, Fatal error: Class 'Controller' not found

Question

Fatal error: Class 'Controller' not found in <local_path>\system\application\controllers\welcome.php on line 3

<?php

class Welcome extends Controller {

    function __construct()
    {
        parent::Controller();   
    }

    function index()
    {
        $this->load->view('welcome_message');
    }
}

/* End of file welcome.php */
/* Location: ./system/application/controllers/welcome.php */

I am beginner in php frameworks just extracted the CodeIgniter zip file and tried to run welcome.php controller in Aptana studio. ( PHP 5 )

What steps are you taking to get to this code? Are you sure you're directing this through index.php instead of accessing this file directly? — treeface

@rabidmachine closing the php tag is optional and sometimes it is helpful check this out us.php.net/basic-syntax.instruction-separation I don't think thats the problem — Brary

@treeface it seems that this is the problem, I was accessing this file directly, but using this route generates page not found? 127.0.0.1:8000/test_ci/index.php/welcome I am installing now WAMP guessing the problem in my routing! — Brary

No need to define constructor of class. This is the code for codeigniter 2.0 or later framework.

class Welcome extends CI_Controller {

    public function index()
    {
        $this->load->view('welcome_message');
    }
}

the problem was that I am accessing this file directly (like what 'treeface' said), but using this route generates page not found?

127.0.0.1:8000/test_ci/index.php/welcome

then I installed WAMP and used

localhost/test_ci/index.php/welcome

and this is working!
sorry for the inconvenience!

Because you are using the code for the older version of CodeIgniter so use this:

class Hello extends CI_Controller
{
    var $name;
    var $color;
    function Hello()
    {
        parent :: __construct();
        $this->name = "Name";
        $this->color = "red";
    }
    function you()
    {
        $data["name"] = $this->name;
        $data["color"] = $this->color;
        $this->load->view("you_view", $data);
    }

}

It seems like you have Codeigniter in a different folder than '/'. If you don't change the BASEPATH or system root path in index.php or config.php, that will lead to problems.

Check lines 14-26 (?) in index.php for the "system" variable.

/*
|---------------------------------------------------------------
| SYSTEM FOLDER NAME
|---------------------------------------------------------------
|
| This variable must contain the name of your "system" folder.
| Include the path if the folder is not in the same  directory
| as this file.
|
| NO TRAILING SLASH!
|
*/
    $system_folder = "system";

Change that to reflect the path of your system folder and CI will surely find your controller class.
