title: Facebook API Access token
body: <p>Hello I am reading the Facebook API docs but I need a simple Help.</p>
  
  <pre><code>$token_url = "https://graph.facebook.com/oauth/access_token?"
         . "client_id=" . $app_id . "&amp;redirect_uri=" . urlencode($my_url)
         . "&amp;client_secret=" . $app_secret . "&amp;code=" . $code;
  </code></pre>
  
  <p>I do understand all the variables...</p>
  
  <p>But I do NOT understand what is <code>$code</code></p>
  
  <p>What is that variable?</p>
  
  <p>I just need to get the last status of the user from the Facebook Feed.</p>
  
  <p>I need to generate the Access Token, but I do not really know what that $code means??</p>
  
  <p>Please help.</p>
