Setting default variables in a controller

mmhhh
basically my "library" looks like this

Code:

class LibAdmin {

function page_vars($controller)
{
switch ($controller){
  case "login":
   $page_vars['db_table'] = 'user';
   $page_vars['title']     = ":: Login";
   $page_vars['heading'] = "Login";
   $page_vars['view'] = "content_login.php";
   $page_vars['metatags'] = array("");
   $page_vars['nav_elements'] = array('extra');
  break;

  case "user":
   $page_vars['db_table'] = 'user';
   $page_vars['title'] = ":: Userverwaltung";
   $page_vars['heading'] = "User";
   $page_vars['view'] = "content_user.php";
   $page_vars['metatags'] = array("");
   $page_vars['nav_elements'] = array('search','add','detail','edit','delete');
  break;
}

$page_vars['timestamp'] = time();
$page_vars['time'] = mdate('%Y-%m-%d %H:%i:%s',$page_vars['timestamp']);
$page_vars['controller'] = $controller;

return ($page_vars);
}

and im using those variables in my functions of the controller and views and so on...
