How can the use of in_array function improve the navigation functionality in PHP scripts?

The in_array function can improve navigation functionality in PHP scripts by allowing us to check if a specific value exists in an array. This can be useful for creating dynamic navigation menus where certain links are displayed based on user permissions or preferences. 

// Example of using in_array for navigation functionality
$allowedPages = ['home', 'about', 'contact', 'profile'];

if (in_array($currentPage, $allowedPages)) {
    // Display navigation links
    foreach ($allowedPages as $page) {
        echo '<a href="' . $page . '.php">' . ucfirst($page) . '</a>';
    }
}
