title: How to add location to a post or a photo with facebook php sdk
body: <p>This is driving me nuts.</p>
  
  <p>Can anyone post a <em>practical</em> example on this? My gratitude for life:</p>
  
  <ol>
  <li>Publish a post and add the related checkin/location info  </li>
  <li>publish a photo and add the related checkin/location info.  </li>
  </ol>
  
  <p>In both cases the user delegates the action to the app. We have the access token by prior.</p>
  
  <p>Please no theory, a working coding snipper ;-)</p>
  
  <p>I am particularly messed up because facebook asks a nested structures of <em>objects</em> and <em>arrays</em></p>
  
  <p>Any help would be really appreciated</p>
