In what scenarios is it more efficient to use a general approach for handling multiple pages based on parameters in the $_GET array in PHP, rather than individual if statements for each page?

When handling multiple pages based on parameters in the $_GET array in PHP, it is more efficient to use a general approach rather than individual if statements for each page. This allows for a more scalable and maintainable codebase, as new pages can be added easily without having to modify the code for each individual page.

if(isset($_GET['page'])) {
    $page = $_GET['page'];
    
    switch($page) {
        case 'home':
            // Code for home page
            break;
        case 'about':
            // Code for about page
            break;
        case 'contact':
            // Code for contact page
            break;
        default:
            // Code for default page or error handling
            break;
    }
}
