title: Acquiring Long Lasting Facebook Token
body: <p>Through Facebook's PHP SDK getting started <a href="https://developers.facebook.com/docs/php/gettingstarted/4.0.0" rel="nofollow">guide</a> it takes you through the process of initializing your app, creating a Login URL and then handling the call back data and doing a simple query.</p>
  
  <p>In the documentation it says you can skip the initializing process providing an access token from 'some other means'.</p>
  
  <pre><code>$session = new FacebookSession('access token here'); 
  </code></pre>
  
  <p>Due to the lack of documentation I'm struggling on how I would define a scope before creating the login URL and then use the call back data to extract the access token.</p>
