How can I make Google News output JSON?
&num=8 should be part of the load request, not url encoded.
Like this...
you can use rsz parameter
rsz=4
This argument supplies an integer from 1–8 indicating the number of results to return per page. e.g.
$url="https://ajax.googleapis.com/ajax/services/search/news?v=1.0&rsz=8&q=Tarun%20Gupta";
