How to check if an entry has been added in Yii2?

Question

Yii

Let's use a simple code:

$user = new Users();
        $user ->name= 'Alex';
        $user ->age= '44';
        $user ->save();

How to find out the number of rows modified (added) by this query?
PDO has $count = $user->rowCount();
Here I tried to do this, but Yii threw an error:

Unknown Method - yii\base\UnknownMethodException
Calling unknown method: app\models\Country::rowCount()

Answer 1

if($user->save()) {
   return 'Пользователь создан';
} else {
   return 'Ошибка';
}
