php yii2大数据分次数循环

$countTrailEnd = ceil(count($dataTrailEnd)/$step);

for($k=0;$k<$countTrailEnd;$k++){
   $prebookTrailDataEnd = array_slice($dataTrailEnd,$k*$step,$step,true);//切割数组

   $query = $connect->createCommand()->batchInsert(\frontend\modules\policy\models\OcrPrebookTrail::tableName()
      ,[
         'prebook_id',
         'prebook_status',
         'operator_id',
         'operator_name',
         'create_time',
         'remark',

      ],$prebookTrailDataEnd);
//相当于insert into table values(),(),();
   if(!$query->execute()){
      Yii::warning("没有添加轨迹数据的上一个id为：".$connect->getLastInsertID()."中".PHP_EOL);
   }
}
