In what scenarios would it be advisable to use nested file structures for generating navigation menus in PHP applications?

Nested file structures are beneficial for generating navigation menus in PHP applications when there are multiple levels of navigation items or a hierarchical structure to the menu. This approach helps to organize the menu items in a logical and structured way, making it easier to manage and update the navigation menu. By using nested file structures, you can create a dynamic and flexible navigation menu that can adapt to changes in the menu structure without the need for manual updates. 

<?php

function generateMenu($items) {
    $menu = '<ul>';
    
    foreach ($items as $item) {
        $menu .= '<li>' . $item['label'];
        
        if (isset($item['children'])) {
            $menu .= generateMenu($item['children']);
        }
        
        $menu .= '</li>';
    }
    
    $menu .= '</ul>';
    
    return $menu;
}

$items = [
    ['label' => 'Home'],
    ['label' => 'About',
        'children' => [
            ['label' => 'Company'],
            ['label' => 'Team']
        ]
    ],
    ['label' => 'Services'],
    ['label' => 'Contact']
];

echo generateMenu($items);

?>
