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 

<?php
$url = $_GET['url'];
$finfo = json_decode(file_get_contents('http://api.ak.facebook.com/restserver.php?v=1.0&method=links.getStats&urls='.$url.'&format=json'));
$tinfo = json_decode(file_get_contents('http://urls.api.twitter.com/1/urls/count.json?url='.$url));
$dinfo = json_decode(file_get_contents('http://feeds.delicious.com/v2/json/urlinfo/data?url='.$url));
$pinfo = json_decode(preg_replace('/^receiveCount\((.*)\)$/', "\\1",file_get_contents('http://api.pinterest.com/v1/urls/count.json?callback=receiveCount&url='.$url)));
$gplus = gplus_shares($url);


//http://papermashup.com/google-plus-php-function/
function gplus_shares($url){
    // G+ DATA
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://clients6.google.com/rpc?key=AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ");
    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":"' . $url . '","source":"widget","userId":"@viewer","groupId":"@self"},
"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]');
    curl_setopt($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 sharedcount.com 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.

The BBC's Working Lunch have put together a short video guide on 'Blogging for beginners' (prepare yourself for dynamic music and quick cutting).
