Yes, you probably do need to implement the iterator interface in the 
users class.  I believe that Smarty uses foreach loops for all iteration 
so that objects with iterator interfaces can be used.  You should also 
get the same error/result if you were to add the following to sandbox.php:

foreach( $users as $user ) {
    echo "Current User: ".$user['id']."<br>";
}
