递归地将数组键中的大写字母重命名为短划线和小写

function renameArrayKeysRecursive($array) {
    $result = array();
    foreach ($array as $key => $value) {
        if (is_string($key) && preg_match('/[A-Z]/', $key)) {
            $newKey = strtolower(preg_replace('/([a-z])([A-Z])/', '$1-$2', $key));
            $result[$newKey] = is_array($value) ? renameArrayKeysRecursive($value) : $value;
        } else {
            $result[$key] = is_array($value) ? renameArrayKeysRecursive($value) : $value;
        }
    }
    return $result;
}

// 示例数组
$array = array(
    "ArrayKey" => "Value",
    "NestedArray" => array(
        "NestedKey" => "NestedValue"
    )
);

// 递归重命名数组键
$renamedArray = renameArrayKeysRecursive($array);

// 输出重命名后的数组
print_r($renamedArray);
