What are the advantages and disadvantages of using IDs to redirect URLs in iframes in PHP?

When using IDs to redirect URLs in iframes in PHP, the main advantage is that it allows for easy and efficient redirection to different URLs within the same iframe. However, a disadvantage is that it may not be the most secure method as IDs can be easily manipulated by users, potentially leading to security vulnerabilities. 

<?php
if(isset($_GET['id'])) {
    $id = $_GET['id'];
    switch($id) {
        case 1:
            $url = "https://example.com/page1";
            break;
        case 2:
            $url = "https://example.com/page2";
            break;
        default:
            $url = "https://example.com/default";
            break;
    }
    echo "<iframe src='$url'></iframe>";
}
?>
