Because you're switching on true/false here, as the result of isset - which is always boolean value - is assigned to $id directly. This line should be rewritten as...

$id = isset($_GET['id']) ? $_GET['id'] : '';

... where '' can be actually replaced with that default value.

In fact, you can redirect user at the very moment when you find that $_GET['id'] is empty, then analyze it's different values with switch. Like this:

if (! isset($_GET['id'])) { ... redirection ... }
switch ($_GET['id']) {
  case 'first': ...; break;
  case 'second': ...; break;
  default: ...;
}
