Php 基于子数组中的值返回父数组键。多维阵列

例如，如果输入

652

或

336

，如何返回钥匙“儿童安全锁”？另一个例子是，如果输入id“84”，则返回数组键“controls”？我尝试使用array_filter（）进行此操作，但无法使其正常工作，是否有人可以为我指出正确的方向

也有此功能，但不起作用

function in_array_r($needle, $haystack, $strict = false) {
    foreach ($haystack as $item) {
        if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict)!==FALSE)) {
            return key($haystack);
        }
    }

    return false;
}

以下各项应起作用：

// Reconstruct array to simplify
$temp = [];
foreach ($arr as $key => $val) {
    $temp[$key] = $val[0];
}
// extract key & required values to a temporary array
$temp = array_combine(array_keys($temp), array_column($temp, 'id'));
// look for the values and extract the key
$key = array_search(84, $temp);

参考-

创建单独的阵列并通过索引访问：

$data = [
    'child-safety-lock' => [
        ['id' => 652, 'name' => 'CHILD LOCK (YES/NO)'],
        ['id' => 336, 'name' => 'CHILD LOCK (YES/NO)'],
        ['id' => 19, 'name' => 'Child Lock'],
    ],
    'controls' => [
        'id' => 84, 'name' => 'CONTROLS (E.G. TOUCH, DIAL )'
    ]
];

$childSafetyLock = array_column($data['child-safety-lock'], 'name', 'id');
$controls = array_column([$data['controls']], 'name', 'id');

var_dump(
    $childSafetyLock[652],
    $childSafetyLock[336],
    $controls[84],
);

或更通用的解决方案：

$data = [
    'child-safety-lock' => [
        ['id' => 652, 'name' => 'CHILD LOCK (YES/NO)'],
        ['id' => 336, 'name' => 'CHILD LOCK (YES/NO)'],
        ['id' => 19, 'name' => 'Child Lock'],
    ],
    'controls' => [
        'id' => 84, 'name' => 'CONTROLS (E.G. TOUCH, DIAL )'
    ]
];

$preparedData = [];
foreach ($data as $key => $value) {
     $preparedData[$key] = (count($value) === count($value, COUNT_RECURSIVE)) 
        ? [$value] 
        : $value;
}

$groupedData = [];
foreach ($preparedData as $key => $value) {
    $groupedData[$key] = array_column($value, 'name', 'id');
}

var_dump(
    $groupedData['child-safety-lock'][652],
    $groupedData['child-safety-lock'][336],
    $groupedData['controls'][84],
);

如果只有一个键具有多个子数组项，并且所有这些ID都是唯一的，则可以将ID映射到键：

<?php

$data =
[
    'biscuits' => [
        [
            'id' => 3,
            'name' => 'Digestive'
        ],
        [
            'id' => 4,
            'name' => 'Rich tea'
        ]
    ],
    'cake' =>
    [
        'id' => 5,
        'name' => 'Victoria'
    ]
];

foreach($data as $k => $item) {
    if($k == 'biscuits') {
        foreach($item as $biscuit) {
            $id_key[$biscuit['id']] = $k;
        }
    }
    else {
        $id_key[$item['id']] = $k;
    }
}
var_export($id_key);

添加了更多的问题。嗨，只有在有多子数组的情况下才有效

array (
    3 => 'biscuits',
    4 => 'biscuits',
    5 => 'cake',
  )
