Laravel 拉威尔阵列

这是我的数据：

$dataItems = [
    [
        'id' => 1,
        'serial' => "XXXXXXAA1",
        'pd_item_info' =>
        [
            'id' => 1,
            'quantity' => 5,
            'ipo_item_pml_info' => 
            [
                'id' => 1,
                'product_name' => 'Keyboard'
            ]
        ]
    ], 
    [
        'id' => 2,
        'serial' => "XXXXXXAA2",
        'pd_item_info' =>
        [
            'id' => 2,
            'quantity' => 10,
            'ipo_item_pml_info' => 
            [
                'id' => 2,
                'product_name' => 'Keyboard'
            ]
        ]
    ]
];

我需要有这个输出：

$output = [
    'product_name' => "Keyboard",
    'serial' =>["XXXXXXAA1", "XXXXXXAA2"]
];

使用laravel中的

foreach

和

array\u push

，我如何合并重复的

product\u name

并加入序列？

我假设

pd\u item\u info

和

ipo\u item\u pml\u info

始终存在

首先根据产品名称识别数组密钥，所有序列密钥都附加在同一产品名称下

foreach($dataItems as $item) {
    $products[$item['pd_item_info']['ipo_item_pml_info']['product_name']][] = $item['serial'];
}

//output
// [
//     'Keyboard' => ['XXXXXXAA1', 'XXXXXXAA2'];
// ]

接下来，根据需要设置格式

foreach($products as $key => $product) {
    $output[] = [
        'product_name' => $key,
        'serial' => $product
    ];
}

就这样=D
