在Laravel中对多维数组应用搜索

function searchInArray($keyword, $array) {
    $results = [];

    foreach ($array as $key => $value) {
        if (is_array($value)) {
            $nestedResults = searchInArray($keyword, $value);
            $results = array_merge($results, $nestedResults);
        } else {
            if (strpos($value, $keyword) !== false) {
                $results[$key] = $value;
            }
        }
    }

    return $results;
}

$array = [
    'name' => 'John Doe',
    'age' => 30,
    'skills' => [
        'programming' => ['PHP', 'JavaScript'],
        'design' => ['Photoshop', 'Illustrator']
    ]
];

$results = searchInArray('PHP', $array);
