title: facebook php $facebook->getLoginUrl email user_location no effect
body: <p>Using the latest Facebook PHP SDK 3</p>
  
  <p>I want to get access to email and possibly user_location, however, when I use the following code, it gets to the Request for Permission page, but I don't see email or user_location listed.......just the normal one that says "Access my basic information'</p>
  
  <pre><code>  $loginUrl = $facebook-&gt;getLoginUrl(array('req_perms' =&gt; 'email, user_location'));
  </code></pre>
  
  <p>then </p>
  
  <pre><code>$user_profile = $facebook-&gt;api('/me');
  </code></pre>
  
  <p>also doesn't return the email...</p>
  
  <p>could someone give me some idea what might be the problem?</p>
  
  <p>I GOT IT</p>
  
  <p>got it, it needs to be 'scope' PHP SDK 3, NOT 'req_perms' =)</p>
