php - file_get_contents & curl returns empty string for google trends -

i tried getting contents of url

http://www.google.com/trends/fetchcomponent?q=ex%20machina&cid=timeseries_graph_0&export=3

with file_get_contents , curl returns nothing, when went directly link shows content not problem api limits etc.

it worked once, not after subsequent calls

heres curl method used

 function get_data($url) {         $ch = curl_init();         //$timeout = 5;         curl_setopt($ch, curlopt_url, $url);         curl_setopt($ch, curlopt_returntransfer, 1);         curl_setopt($ch, curlopt_proxyport, 3128);         curl_setopt($ch, curlopt_ssl_verifyhost, 0);         curl_setopt($ch, curlopt_ssl_verifypeer, 0);         $data = curl_exec($ch);         curl_close($ch);         return $data;     }
