Why doesn't foreach work in yii2?

Question

Yii

Everything is displayed through the wardump, so $news1[0]["title"] is also displayed, but not through foreach.

<?php
echo "<pre>";
echo var_dump($news1);
echo "</pre>";
//?>
<?//=$news1[0]["title"]?>
<?//=$news1[1]["title"]?>
<?//=$news1[2]["title"]?>
<?foreach ($news1 as $val){?>
  <?=$val?>
<?}?>

controller

public function actionNews1()
  {
    $news1 = News1::find()->all();
    return $this->render('news1',[
      'news1' => $news1
    ]);
  }

model

namespace app\models;
use Yii;
use yii\db\ActiveRecord;
class News1 extends ActiveRecord{
}

var_dump

array(3) {
  [0]=>
  object(app\models\News1)#67 (8) {
    ["_attributes":"yii\db\BaseActiveRecord":private]=>
    array(3) {
      ["id"]=>
      int(1)
      ["title"]=>
      string(18) "Страница 1"
      ["content"]=>
      string(23) " содержимое 1"
    }
    ["_oldAttributes":"yii\db\BaseActiveRecord":private]=>
    array(3) {
      ["id"]=>
      int(1)
      ["title"]=>
      string(18) "Страница 1"
      ["content"]=>
      string(23) " содержимое 1"
    }
    ["_related":"yii\db\BaseActiveRecord":private]=>
    array(0) {
    }
    ["_errors":"yii\base\Model":private]=>
    NULL
    ["_validators":"yii\base\Model":private]=>
    NULL
    ["_scenario":"yii\base\Model":private]=>
    string(7) "default"
    ["_events":"yii\base\Component":private]=>
    array(0) {
    }
    ["_behaviors":"yii\base\Component":private]=>
    array(0) {
    }
    ...
 }
}

It also doesn't throw any errors.
Maybe the problem is in SQL or that there is no public access?

Answer 1

<?php foreach ($news1 as $val){?>
  <?= var_dump($val); ?>
<? } ?>

What will var_dump($val) show? An object. If you want to display the title, then it is done like this:

<?php foreach ($news1 as $val){?>
  <?= $val->title; ?>
<? } ?>
