PHP中的多維數組推送

Question

    <?php
$userData = [
    [
        "UID" => "5f10482574d83d4b726fe5",
        "name" => "Yug Gill",
        "orgID" => "5f10481d74d83d4b726",
        "imageURL" => "female.png"
    ]
];

$userProductsData = [
    [
    "UPID" => "5f10482574d83d4b6fe007",
    "UID" => "5f10482574d83d4b726fe5",
    ]
];
$userDetailsResult = [];
foreach ($userData as $key => $value) {
    $userData[$key]["UPID"] = $userProductsData[$value["UID"]] ?? [];
}

預期產出

$userData = [
    [
        "UID" => "5f10482574d83d4b726fe5",
        "name" => "Yug Gill",
        "orgID" => "5f10481d74d83d4b726",
        "imageURL" => "female.png",
        "UPID" => "5f10482574d83d4b6fe007"
    ]
];

我有兩個數組通用的數組UID ，現在我想從$userProductsData獲取 UPID 並推送到$userData ，我試過無法正常工作，請任何人更新我的代碼？>

Answer 1

試試這個。

$userData = [
    [
        "UID" => "5f10482574d83d4b726fe5",
        "name" => "Yug Gill",
        "orgID" => "5f10481d74d83d4b726",
        "imageURL" => "female.png"
    ]
];

$userProductsData = [
    [
    "UPID" => "5f10482574d83d4b6fe007",
    "UID" => "5f10482574d83d4b726fe5",
    ]
];
$userDetailsResult = [];

foreach ($userProductsData as $key => $value) {
    $userData[$key]["UPID"] = $value['UPID'];
   
}

print_r($userData);

Answer 2

您的$userProductsData是一個常規數組，它具有索引 0、1、2 等......然后您試圖通過字符串鍵"5f10482574d83d4b726fe5"從該數組中獲取一個項目。

$userProductsData應該是這樣的鍵數組：

$userProductsData = [
    "5f10482574d83d4b726fe5" => [
        "UPID" => "5f10482574d83d4b6fe007",
        "UID" => "5f10482574d83d4b726fe5",
    ],
];

然后你可以通過鍵"5f10482574d83d4b726fe5"從這個數組中獲取一個項目。
