Что выводит yii2?

Question

[Максим]

Есть база данных по имени u13461( в ней есть таблица result и 3 поля id,date,result)
Создаю файл модели results.php(В папке models)
Пишу тут

namespace app\models;

use yii\db\ActiveRecord;

class results extends ActiveRecord
{
    const STATUS_INACTIVE = 0;
    const STATUS_ACTIVE = 1;

    /**
     * @return string название таблицы, сопоставленной с этим ActiveRecord-классом.
     */
    public static function tableName()
    {
        return 'result';

    }
}

Далее в контролере SiteController пишу

use Yii;
use yii\filters\AccessControl;
use yii\web\Controller;
use yii\filters\VerbFilter;
use app\models\EntryForm;
use app\models\results;

class SiteController extends Controller
{
    public function actionIndex()
    {
         $query = results::find()->all();
            return $this->render('index', [
                'query' => $query
            ]);
        }
}

В views файле index.php пишу:

echo "<pre>";
    print_r($query);
    echo "</pre>";

В итоге, по мимо данных из базы я получаю еще куча данных в непонятной структуре и данные из базы дублируются.
Почему?
Вот что показывает:

Array

    [0] => app\models\results Object
        (

Решил, нужно в запросе добавить asArray()->all();
