To create a new controller, create a new PHP class inside the controller folder. Name it CookingController.php. The reason for this? You have been doing this for a while now, so you should continue doing it lest your stomach gets angry. Keep cooking, comrade.
To create a new controller, go to a new PHP class. Use the name CookingController.php. Do remember the directory <project-root>/app/controllers. Your controller will look somewhat like the following code:
namespace app\controllers;
use app\models\Cooking;
use Yii;
use yii\web\Controller;
class CookingController extends Controller
{
public function actionIndex(){
$items = new Cooking();
$dishname = 'pizza';
$ingredients = $items->getIngredients();
$toppings = $items->getToppings();
return $this>render('index',array('dishname'=>$dishname,
'ingredients'=>$ingredients,'toppings' => $toppings));
}
}
