php - 合并多维数组匹配

Question

我正在开发我们的订单系统，以显示每个部门需要完成的特定订单。我在多维数组中拥有所有必要的数据。但我想合并具有相似值的任何数组。

Array
(
    [0] => Array
    (
        [id] => 16111
        [order_id] => 1234
        [item_id] => Product 1
        [invoice_id] => 98765
        [acc_id] => 1
        [name] => John Smith
        [phone] => 000000000
    )

    [1] => Array
    (
        [id] => 16112
        [order_id] => 1234
        [item_id] => Product 2
        [invoice_id] => 98765
        [acc_id] => 1
        [name] => John Smith
        [phone] => 000000000
    )

    [2] => Array
    (
        [id] => 16113
        [order_id] => 1235
        [item_id] => Product 3
        [invoice_id] => 98721
        [acc_id] => 11
        [name] => Bob Jones
        [phone] => 222222222
    )

    [3] => Array
    (
        [id] => 16114
        [order_id] => 1236
        [item_id] => Product 4
        [invoice_id] => 98754
        [acc_id] => 3
        [name] => Fred Bill
        [phone] => 111111111
    )

    [4] => Array
    (
        [id] => 16115
        [order_id] => 1236
        [item_id] => Product 1
        [invoice_id] => 98754
        [acc_id] => 3
        [name] => Fred Bill
        [phone] => 111111111
    )
)

我们可以看到我们有 5 个产品要发送给客户。但约翰·史密斯和弗雷德·比尔都想要多件元素。我宁愿将其作为每个客户的数组，而不是将数据存储在每个项目的数组中。基于订单 ID。所以我希望数组最终看起来像这样。

Array
    (
    [0] => Array
    (
        [0] => Array 
            (
                [id] => 16111
                [order_id] => 1234
                [item_id] => Product 1
                [invoice_id] => 98765
                [acc_id] => 1
                [name] => John Smith
                [phone] => 000000000
            )
        [1] => Array
            (
                [id] => 16112
                [order_id] => 1234
                [item_id] => Product 2
                [invoice_id] => 98765
                [acc_id] => 1
                [name] => John Smith
                [phone] => 000000000
            )
    )

    [1] => Array
    (
        [id] => 16113
        [order_id] => 1235
        [item_id] => Product 3
        [invoice_id] => 98721
        [acc_id] => 11
        [name] => Bob Jones
        [phone] => 222222222
    )

    [2] => Array
    (
        [0] => Array
            (

                [id] => 16114
                [order_id] => 1236
                [item_id] => Product 4
                [invoice_id] => 98754
                [acc_id] => 3
                [name] => Fred Bill
                [phone] => 111111111

            )
        [1] => Array
            (
                [id] => 16115
                [order_id] => 1236
                [item_id] => Product 1
                [invoice_id] => 98754
                [acc_id] => 3
                [name] => Fred Bill
                [phone] => 111111111
            )



    )

产品 1 也是邮政和包装，因此我希望将数据回显到表中。但我不希望“邮政”和“包装”拥有自己的行，而是在该数组中其他产品的行中确定一个字段。因此，在表格中我们会看到例如:

• John Smith Product2 Courier(根据产品 1 的存在而确定)000000000

如果客户有多种产品，则这需要起作用

• John Smith Product3 Courier(由产品 1 是否存在确定)000000000
• John Smith Product4 Courier(由产品 1 是否存在确定)000000000
• John Smith Product5 Courier(由产品 1 是否存在确定)000000000

Answer 1

你在寻找这样的东西吗？

foreach($array as  $order)
{
    $orders[$order['order_id']][] = $order; 
}

它按 order_id 对所有订单进行分组
