title: Facebook integration through PHP sdk OR Javascript sdk for my PHP codeigniter based website
body: <p>I am doing FaceBook integration of my codeigniter based web application, I want to avail the facility of a user being able to log into my site using his Facebook login Id and pass.</p>
  
  <p>The easiest method as mentioned here is <a href="http://developers.facebook.com/docs/concepts/login/login-architecture/" rel="nofollow">http://developers.facebook.com/docs/concepts/login/login-architecture/</a> is by using Client side JavaScript SDK.(Correct me if I am wrong, I also would love to follow if possible even more easier methods.)</p>
  
  <p>But I am little confused as there are PHP sdk's also available and I have heard that the PHP sdk is the only way one can authenticate certain parts of Facebook and it is the only way we can access Facebook data through FQL.</p>
  
  <p>Which way to go?  </p>
  
  <p>Any help will be highly appreciated.</p>
