title: What is a good web service for ajax interactions? in Zend Framework context?
body: <p>When you are designing a page that will use javascript and ajax to interact with your server, what is the best technology you should use?</p>
  
  <p>What I mean by using is basically things like sending and receiving data for simple CRUD, and things like autocompletion and search.</p>
  
  <p>I usually write my own server, I read the $_POST variable, and I use Jquery's jQuery.post() to send stuff to the server and also read stuff.</p>
  
  <p>I was wondering if I should use a more standard protocol such as:</p>
  
  <ul>
  <li>XML_RPC </li>
  <li>REST</li>
  <li>SOAP</li>
  <li>JSON_RPC</li>
  </ul>
  
  <p>Please tell me if I should be using any of these or something else, and also justify your response as to what protocol/technology is more suited for these kind of things.</p>
