How can PHP developers ensure proper navigation and user experience when implementing dynamic menus in WordPress?

To ensure proper navigation and user experience when implementing dynamic menus in WordPress, PHP developers can use the `wp_nav_menu()` function provided by WordPress. This function allows developers to easily create dynamic menus that can be customized through the WordPress admin panel. By properly setting up menu locations and assigning menus to those locations, developers can ensure that navigation is consistent and user-friendly across the website.

// Registering a custom navigation menu location
function register_custom_menu() {
    register_nav_menu('primary-menu', __('Primary Menu'));
}
add_action('after_setup_theme', 'register_custom_menu');

// Displaying the custom navigation menu
wp_nav_menu(array(
    'theme_location' => 'primary-menu',
    'menu_id' => 'primary-menu',
    'container' => 'nav',
    'container_class' => 'primary-menu'
));
