How can PHP switch statements be effectively used in conjunction with inline frames for website navigation?

When using inline frames for website navigation, PHP switch statements can be effectively used to determine which page to load within the frame based on user input. By using a switch statement with cases for each navigation option, you can easily control the content displayed in the inline frame. This allows for a more dynamic and organized navigation system within the website.

<?php
// Get the page parameter from the URL
$page = isset($_GET['page']) ? $_GET['page'] : 'home';

// Use a switch statement to determine which page to load
switch ($page) {
    case 'home':
        include 'home.php';
        break;
    case 'about':
        include 'about.php';
        break;
    case 'services':
        include 'services.php';
        break;
    case 'contact':
        include 'contact.php';
        break;
    default:
        include '404.php';
        break;
}
?>
