HTML menu generation from a nested array

It is necessary to convert a nested array into HTML menu markup. The input data is a multidimensional array where each element can contain keys label, url, and optionally items — an array of child items. The task is to traverse the structure and output the corresponding <ul>/<li> list with links.

<?php

$navItems = [
    [
        'label' => 'Yil framework',
        'url' => 'https://yilframework.ru',
    ],
    [
        'label' => 'More Frameworks',
        'items' => [
            ['label' => 'Laravel', 'url' => 'http://laravel.com/'],
            ['label' => 'Slim', 'url' => 'http://www.slimframework.com/'],
        ],
    ],
    [
        'label' => 'Symfony',
        'url' => 'https://symfony.com/',
    ],
];

?>
