get number of comments of fb and g

In an hackish way you can ex:

function get_count_gplus($url){
	$req = wp_remote_get('https://apis.google.com/_/widget/render/commentcount?bsv&usegapi=1&href='.$url);
	if (is_wp_error($req) || $req['response']['code'] != 200) return '0';
	$body = $req['body'];
	$count = explode("<span>",$body);
	$count = $count[1];
	$count = explode(" ",trim($count));
	return $count[0];
}
