title: is admin on facebook pages
body: <p>I looked around and could not find anything to do this (well it was not obvious or semi-obvious)</p>
  
  <p>So say i have a facebook application that offers a service that people will pay for during use.  The average user can come on and "Subscribe" to it, while the admin of those pages can perform an activity that will cost them money (make me money).  </p>
  
  <p>I do not want hacking attempts or anything to hurt our product.  So, how can i verify that someone is an admin using the PHP SDK.</p>
  
  <p>What we are currently doing is storing the $_POST["signed_request"] in $_SESSION's data and working with that.  Either the $_POST or $_SESSION is not safe 100% (firesheep).</p>
  
  <p>Is there any way to verify this? graph api? </p>
