Question

我有一个数组如下。 atrributes是每个数组的order_id，qty，sell_price，product_name和merchant_name。我想基于相同的order_id进行映射，如果相同的order_id大于1，则将属性更改为数组。

[items:protected] => Array
    (
        [0] => stdClass Object
            (
                [order_id] => 1
                [qty] => 1
                [sell_price] => 45000.00
                [product_name] => Omni Bars Cokelat Kelapa
                [merchant_name] => Health & Co.
            )

        [1] => stdClass Object
            (
                [order_id] => 1
                [qty] => 1
                [sell_price] => 55000.00
                [product_name] => Trim Eats Strawberry Banana Cream Overnight Oats
                [merchant_name] => Trim Eats
            )

        [2] => stdClass Object
            (
                [order_id] => 1
                [qty] => 1
                [sell_price] => 28000.00
                [product_name] => Everything Banana Keripik Pisang Rumput Laut
                [merchant_name] => EverythingBanana
            )

        [3] => stdClass Object
            (
                [order_id] => 2
                [qty] => 1
                [sell_price] => 35000.00
                [product_name] => Naked Bar Banana Nutter
                [merchant_name] => Naked Foodss
            )

        [4] => stdClass Object
            (
                [order_id] => 3
                [qty] => 1
                [sell_price] => 200000.00
                [product_name] => Health & Co. Paket Detoks 1 Hari
                [merchant_name] => Health & Co.
            )

        [5] => stdClass Object
            (
                [order_id] => 3
                [qty] => 1
                [sell_price] => 38000.00
                [product_name] => Health & Co. Paket 3 Botol Holy Kale
                [merchant_name] => Health & Co.
            )

   )

我想将数组映射到类似的东西，键是order_id。

   [1] => stdClass Object
        (
            [qty] => [1,1,1]
            [sell_price] => [45000.00, 55000.00, 28000.00]
            [product_name] => [Omni Bars Cokelat Kelapa, Trim Eats Strawberry Banana Cream Overnight Oats, Everything Banana Keripik Pisang Rumput Laut]
            [merchant_name] => [Health & Co, Trim Eats, EverythingBanana]
        )
   [2] => so on....

我坚持下去。请帮帮我。

看看这个解决方案：

//$data - your array

$result = [];
foreach ($data as $item) {
    $result[$item['order_id']]['qty'][] = $item['qty'];
    $result[$item['order_id']]['sell_price'][] = $item['sell_price'];
    $result[$item['order_id']]['product_name'][] = $item['product_name'];
    $result[$item['order_id']]['merchant_name'][] = $item['merchant_name'];
}

// $result your result array
