title: Use HTTP_Request response content
body: <p>I have an <code>HTTP_Request2_Response</code> variable which when I echo using <code>$response-&gt;getBody()</code>  gives me this:</p>
  
  <pre><code>{"results":["element1","element2","element3"],"id":"elementID"}
  </code></pre>
  
  <p>Is there any way to get each element like <code>$respons["id"]</code>? Is there any way to convert these results into a json object?</p>
