我想要的效果：

 

 不使用array_reduce 的效果 ：

代码： 

    public function teamList($userId,$good_id)
    {
        $nowbuyers = $this->order->where('good_id',$good_id)->count();
        $data = GroupTotalOrder::alias('t_order')->where('merchant_Id',$userId)->leftJoin('dg_goods good','t_order.good_id = good.id')->field("t_order.*,good.id,good.photo,good.name,good.type,good.price,good.tag")->select()->toArray();
        if(!$data){
            return $this->fail("没有找到团购的香相关信息");
        }

        $data = array_reduce($data, function ($carry, $item) use ($nowbuyers) {
            $carry[] = array_merge($item, ['nowbuyers' => $nowbuyers]);
            return $carry;
        }, []);


//        dump($data);die();
        $data['nowbuyers'] = $nowbuyers;
        return $this->success("获取数据成功",$data);
    }
