title: Converting json to jsonp
body: <p>I just created an account on 500px.com, and would like to use their API: <a href="http://developer.500px.com/" rel="nofollow">http://developer.500px.com/</a></p>
  
  <p>But it looks like it cant return JSONP, only JSON. </p>
  
  <p>Is there any way to make a php file that you can post a url to -> make it convert the response from the api from JSON to JSONP, so i can handle it on the client side? </p>
  
  <p>I havent been writing any PHP in a long time, so any help is appreciated. Hope you get the idea, otherwise ill elaborate. Thanks</p>
