What are the drawbacks of using frames to hide URL parameters in PHP?

Using frames to hide URL parameters in PHP can cause issues with accessibility, SEO, and user experience. Instead, it is recommended to use server-side methods like sessions or cookies to store and pass sensitive information. 

session_start();

$_SESSION['user_id'] = 123;

// To retrieve the user_id in another page
session_start();
$user_id = $_SESSION['user_id'];
