What are the advantages of using multidimensional arrays for managing navigation links in PHP?

Using multidimensional arrays for managing navigation links in PHP allows for organizing the links in a structured manner, making it easier to add, remove, or modify links. It also enables you to easily loop through the array to generate the navigation menu dynamically. This approach helps in maintaining a clean and scalable codebase for navigation management.

php 
// Example of using multidimensional arrays for managing navigation links

$navigationLinks = [
    'Home' => ['url' => 'index.php'],
    'About' => ['url' => 'about.php'],
    'Services' => [
        'Web Development' => ['url' => 'web-development.php'],
        'Graphic Design' => ['url' => 'graphic-design.php'],
    ],
    'Contact' => ['url' => 'contact.php'],
];

// Loop through the multidimensional array to generate the navigation menu
foreach ($navigationLinks as $key => $value) {
    if (is_array($value)) {
        echo "<li>$key<ul>";
        foreach ($value as $subKey => $subValue) {
            echo "<li><a href='{$subValue['url']}'>$subKey</a></li>";
        }
        echo "</ul></li>";
    } else {
        echo "<li><a href='{$value['url']}'>$key</a></li>";
    }
}
