PHP code to bulk collect social share counts from Facebook, Twitter, Delicious, Pinterest and Google +1s and return json

A little snippet of code I’m using to get share counts for a url from a number of services in one call. The idea is I pass a url and I get some json back with counts from Facebook, Twitter, Delicious, Pinterest and Google +1s (if it’s a bad url or nothing returned from the service then null value).

json returned  

$url = $_GET['url'];
$finfo = json_decode(file_get_contents(''.$url.'&format=json'));
$tinfo = json_decode(file_get_contents(''.$url));
$dinfo = json_decode(file_get_contents(''.$url));
$pinfo = json_decode(preg_replace('/^receiveCount\((.*)\)$/', "\\1",file_get_contents(''.$url)));
$gplus = gplus_shares($url);
function gplus_shares($url){
// G+ DATA
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, '[{"method":"pos.plusones.get","id":"p",
"params":{"nolog":true,"id":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
$result = curl_exec ($ch);
curl_close ($ch);
return json_decode($result, true);
$output = array(
'facebook'=> isset($finfo[0]) ? $finfo[0]->total_count : NULL,
'twitter'=> isset($tinfo->count) ? $tinfo->count : NULL,
'delicious'=> isset($dinfo[0]) ? $dinfo[0]->total_posts : NULL,
'pinterest'=> isset($pinfo->count) ? $pinfo->count : NULL,
'googlePlus'=> isset($gplus[0]['result']) ? $gplus[0]['result']['metadata']['globalCounts']['count'] : NULL
header('Content-Type: text/javascript');
echo "[".json_encode($output)."]";

Usually I use for this, but was worried that give over 15k urls to get data on I might trip their server (although I was given assurances that it was fine). I’ve deployed this code on a local webserver (XAMPP Lite) and it’s working well in parallel with Google Refine.
