Smarty从PHP中的.conf文件中读取配置值

Question

For a meeting schedule, I want to have dynamic pages for any given room. User can edit a file named "schedules.conf" in the config folder. At the moment it looks like this:

[rooms]
room = 5022
room = 5082

And I can load it normally and it shows 2 links in my web page:

{config_load file="schedules.conf" section="rooms"}
......
......
......

{foreach from=#room# item=r}

<li><span><span><a href="{$smarty.const.SITE_URL}/admin/schedules.list.php?room={$r}">Schedules {$r}</a></span></span></li>                    

{/foreach}

So it links to the handler PHP file, now in the php file I want to check weather that room exist in the config file, so if someone manually change the GET value for room in the address bar I could have a chance to handle that:

  if(!isset($_GET["room"]))
  {
      header('location: '.SITE_URL.'/admin/index.php');
  }
  else
  {
      $validRooms = $smarty->getConfigDir();

      //How to check id the $_GET["room"] value exist in the config file      
  }

Grep this page Conditional checks using smarty for isset()

EDIT

In light of comment #1 by the OP:

How about use a conditional check along with in_array($_GET['room'], $validRooms)
