详细解说php基于laravel框架的批量插入（教程）

$ret = [];
    $create_red = new create_red();
    foreach($arr3 as $v){
      $delayDays = $v->delayDays;
      $workDays = $v->workDays;
      //获取当天时间戳的0点
      $now = strtotime(date('Y-m-d',time()));  ;
      $start = $now + $delayDays*86400;
      $start_at = date("Y-m-d H:i:s",$start);
      $end =  $now + $delayDays*86400 + $workDays*86400;
      $end_at = date('Y-m-d H:i:s',$end);
      $created_at = date("Y-m-d H:i:s",$now);
      $ret[] = [
        'uid'=>$uid,
        'status'=>1,

        'start_at'=>$start_at,
        'end_at'=>$end_at,
      ];
    }
    //往数据库批量插入数据
    $result = $create_red::insert($ret);
    if(!$result){
      DB::rollBack();
      return MyResponse::error(9006,'兑换优惠券失败');
