php按子键值对多层深度的多维数组进行排序

function multiArraySort(&$array, $key)
{
    if (!is_array($array)) {
        return;
    }

    // 对当前层级的数组进行排序
    usort($array, function ($a, $b) use ($key) {
        return $a[$key] <=> $b[$key];
    });

    // 对子数组进行排序
    foreach ($array as &$subArray) {
        if (is_array($subArray)) {
            multiArraySort($subArray, $key);
        }
    }
}

// 示例多维数组
$multiArray = [
    [
        'name' => 'John',
        'age' => 25,
        'skills' => [
            [
                'name' => 'PHP',
                'level' => 'Intermediate'
            ],
            [
                'name' => 'JavaScript',
                'level' => 'Advanced'
            ]
        ]
    ],
    [
        'name' => 'Jane',
        'age' => 30,
        'skills' => [
            [
                'name' => 'PHP',
                'level' => 'Advanced'
            ],
            [
                'name' => 'JavaScript',
                'level' => 'Intermediate'
            ]
        ]
    ]
];

// 按子键值'name'对多维数组进行排序
multiArraySort($multiArray, 'name');

// 输出排序后的多维数组
print_r($multiArray);
