What are the limitations of using PHP for creating nested navigation menus with subcategories?

One limitation of using PHP for creating nested navigation menus with subcategories is that it can become complex and difficult to manage as the depth of the menu increases. To solve this issue, you can use recursive functions to dynamically generate nested HTML elements for each level of the menu. 

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

// Example usage
$menuItems = [
    ['name' => 'Home'],
    ['name' => 'Products', 'children' => [
        ['name' => 'Category 1'],
        ['name' => 'Category 2', 'children' => [
            ['name' => 'Subcategory 1'],
            ['name' => 'Subcategory 2']
        ]]
    ]],
    ['name' => 'About Us']
];

echo generateMenu($menuItems);
