I need to print first segment variable in my function from \_\_construct, but I get error:

Code:

```
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Main extends CI_Controller {

    public $data = array();

    public function __construct()
    {
        parent::__construct();
        $data['seg'] = $this->uri->segment(1);
        $data['seg'] == 'en' ? $data['seg'] = 'en' : $data['seg'] = 'ge';
    }

    public function index()
    {
        echo "test";
    }

    public function Test()
    {
        echo $data['seg'] . " - TEST";
    }

}

/* End of file  */
/* Location: ./application/controllers/Main.php */

```

Error:

```
