How to add yii framework in batches

#Yii's ar class seems to have some problems with batch inserting data, or I haven't found a method.

Here we will first record another Yii batch insertion method, and later find the ar class batch insertion method and record it. (Recommended learning: yii framework )

$arr =[];
                        for ($i=0; $i < count($photolist); $i++) { 
                            $arr[$i][] = $titlelist[$i];
                            $arr[$i][] = $photolist[$i];
                            $arr[$i][] = $desclist[$i];
                        }

                        Yii::$app->db->createCommand()->batchInsert(&#39;designlist&#39;, [&#39;name&#39;,&#39;photourl&#39;,&#39;desc&#39;], $arr)->execute();

（The current $ Arr is a two -dimensional array, so. Successfully implemented batch insertion of data in yii2

yii2一次插入多行数据
 /**
     * @inheritdoc  批量添加
     * @params   $add  array 添加数据
     */
    public function add_all($add)
    {
      $connection = \Yii::$app->db;
      //数据批量入库
      $connection->createCommand()->batchInsert(
        'zss_stat_series',
        ['series_name','series_turnover','created_at'],//字段
        $add
      )->execute();
    }
