我想要上面数组中的唯一对象..所以，所需的输出是：
array:4 [▼
0 => {#445 ▼
+"prod_id": "276" // <== Earlier 3, now 1.

+"prod_quantity": "4"
+"ord_prd_code": "B-V-001"

我有以下代码：
$recentlySoldProducts = DB::table('products')
->join('orders', 'orders.product_id', '=', 'products.id')
->where('products.display', '=', 'Enabled')
->where('products.deleted_at', '=', NULL)
->select(
'products.id AS prod_id',
'products.name AS prod_name',
'products.code AS prod_code',
'products.price AS prod_price',
'products.discount_price AS prod_disc_price',
'products.discount_percent AS prod_disc_percent',
'products.img_code AS image_code',
'products.enquire AS prod_enquiry',
'products.quantity AS prod_quantity',
'orders.product_code AS ord_prd_code',
'orders.order_code AS ord_code',
'orders.product_option_code AS ord_prd_opt_code',
'orders.id AS order_id',
'orders.product_id AS order_product_id'
)->groupBy(['order_product_id', 'ord_code'])
->orderBy('orders.id', 'desc')->take(18)->get();
我想要实现的是最近销售的产品块。无论何时下订单，这些产品最近都会在这里出售。如果1个产品以不同的订单多次出售，我想合并该产品并将其作为1个产品，而不是重复产品，否则按原样获取订购的产品。
我应该如何实现这一目标？感谢。
我正在使用Laravel 5.0。*用于此应用程序..
答案 0 :(得分：0)
您可以在商品ID上添加GROUP BY，这样就不会添加任何重复项。
使用查询构建器，它看起来像这样：
$recentlySoldProducts = DB::table('products')
->join('...')
->where('...')
->select('...')
->groupBy('products.id')
->orderBy('orders.id', 'desc')->limit(18)->get();
