Global Variable?

If you need this like a global then use the static keyword.

PHP Code:

class A_Controller extends CI_Controller {

  protected static $global = 0;

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

  public function setGlobal($value){
    self::$global = $value;
    $this->index();
  }

  public function index(){
    echo self$global;
  }

}
