title: Map JSON to php object
body: <p>I have a JSON which has the following structure, but I am only interested in the data inside <code>entries</code> node, therefore my DTO class's fields mirrors the tags inside the said node. But as expected I get an error when deserializing the JSON since JMSserializer expects an object which contains fields for all the tags in the JSON. Is there a way I can ignore the other tags? What is the proper way to accomplish this?</p>
