Hi! I have some controller like this

 public function actionIndex($id){      
     $id = Yii::$app->request->get('id');

Advise me please how can i validate that ‘id’ is int or in_array(‘sale’,‘wait’) with yii2 tools

Do you mean that ‘id’ can be an integer or a fixed string that is ‘sale’ or ‘wait’?
Then I would write something like this:

    public function actionIndex($id)
    {
        // $id = Yii::$app->request->get('id');  // no need to do this
        if ($id == 'sale') {
            ...
        } elseif ($id == 'wait') {
            ...
        } elseif ($id > 0 ) {
            ...
        }
    }

You don’t have to read ‘id’ from GET parameter by yourself, because Yii will do it for you.

Or, I would prefer a cleaner code:

    public function actionIndex($id, $operation = null) 
    {
        if ($operation == 'sale') {
            ...
        } elseif ($operation == 'wait') {
            ...
        } else {
            ...
        }
    }
