How can PHP developers ensure smooth integration of navigation menus when adding new modules to a project?

When adding new modules to a PHP project, PHP developers can ensure smooth integration of navigation menus by using a modular approach. By creating a separate file for the navigation menu that can be included in all pages, developers can easily update the menu without affecting the rest of the codebase. This allows for seamless integration of new modules without having to manually update the navigation menu in every page. 

// navigation_menu.php

<nav>
    <ul>
        <li><a href="index.php">Home</a></li>
        <li><a href="about.php">About</a></li>
        <li><a href="contact.php">Contact</a></li>
        <!-- Add new menu items here -->
    </ul>
</nav>
```

To include the navigation menu in a PHP file:

```php
// index.php

<?php include 'navigation_menu.php'; ?>

<!-- Rest of the page content -->
