title: getting invalid token from facebook PHP
body: <p>Here is my code that checks if the user has authorized the app or not</p>
  
  <pre><code> $customer_id = $facebook-&gt;getUser();
      echo 'My customer ID is '.$customer_id;
      echo $facebook-&gt;getAccessToken();
  </code></pre>
  
  <p>Even I have removed the app from my facebook it is giving me correct <code>fb Id</code> and <code>appId|secretId</code> as token,</p>
  
  <p>Any idea what could be the reason, the same code was working fine few hours back, any Idea what could be the reason or how to get refreshed data from fb?</p>
