title: how to build a batch job to post a wall-to-wall facebook post using php
body: <p>I have written a facebook app. I want to write a batch job using php to post a wall-to-wall post to user A and his friend B (B is not the app user) such that the post is a wall-to-wall post as user A-> B. </p>
  
  <p>I have tried the graph feed api but can only post to user A wall and say I have no right to post to B's wall. In fact I found some apps have done similar things and i guess it is a batch job (as the post is released when I am not using the app).</p>
  
  <p>As it is a batch job, i dont have user's access_token. Is it possible to do it?</p>
