How can the code be adjusted to handle the deletion process when the register_globals setting is off in PHP?

When the register_globals setting is off in PHP, variables are not automatically imported into the global scope from the request. To handle the deletion process in this scenario, you can use PHP's $_GET or $_POST superglobals to access the parameters passed in the request.

$id = $_GET['id'];

// Perform deletion process using the $id variable
