我想要从我的网站购买的用户数量图表。我该如何实现？

$ordersArr = Order::where('vendor_id',$id)
        ->whereBetween('created_at',[$carbonStart,$carbonEnd])
        ->get();

我的表如下 订购

user_id  count  date
  1        2    2019-03-30
  1        2    2019-03-29 
  2        2    2019-03-30
  2        3    2019-03-29

Answer 1

$data = DB::table('order')
        ->select(DB::raw('user_id,count(*) as vendor_id,created_at as date'))
        ->whereBetween('created_at',[$carbonStart,$carbonEnd])
        ->groupBy('user_id')->get();
