Laravel array_push

Question

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'
            ]
        ]
    ]
];

并且我需要输出：

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

在laravel中使用foreach和array_push，如何合并重复的product_name并在那里串行连接？

Answer 1

我假设pd_item_info和ipo_item_pml_info一直在那里

首先根据产品名称区分阵列键，所有序列号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'];
// ]

下一步，根据您的需要进行格式化

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