title: Parse error while decoding json to array
body: <p>Below  is my JSON string</p>
  
  <pre><code>{"ticket_action":"Updated","id":"4214","title":"test_123456","description" :"This request was closed and merged into request #4192 "test_2".","tags": "closed_by_merge","status": "Closed","update_time":"2016-02-26T00:56:07-08:00","phone":"+919898989898"}
  </code></pre>
  
  <p>When I am trying to decode it using <code>json_decode($json_string,true)</code>;
  it is not decoding.</p>
  
  <p>I think issue is because of "test_2"."  in json string (nested double quotes).
  I have tried with escape function but did't get any success.
  Is their any way to decode this string?</p>
