Is using framesets to maintain a consistent URL structure a recommended practice in PHP development?

Using framesets to maintain a consistent URL structure is not a recommended practice in PHP development. Framesets can cause issues with accessibility, SEO, and usability. Instead, it is better to use PHP to dynamically generate content and maintain a clean URL structure using routing techniques.

// Example of using PHP routing to maintain a consistent URL structure
// index.php

// Router function to handle different URL routes
function route($url) {
    switch ($url) {
        case '/':
            include 'home.php';
            break;
        case '/about':
            include 'about.php';
            break;
        case '/contact':
            include 'contact.php';
            break;
        default:
            include '404.php';
            break;
    }
}

// Get the current URL path
$url = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);

// Route the request
route($url);
