There is also a short form echo tag enabled on most PHP servers 
On the subsequent page you retrieve the parameter from the GET array:
$subject = $_GET['id'];

If you're passing this value to the database you should do some validation:
if ($_GET['id']) { // check parameter was passed
  $subject = int_val($_GET['id']) // cast whatever was passed to integer
} else {
  // handle no subject case
}
