about facebook login!
print out getPicture () in this format:
{"height":50,"is_silhouette":false,"url":"https:\/\/lookaside.facebook.com\/platform\/profilepic\/?asid=xxx&height=50&width=50&ext=xxx&hash=xxsxsxsxsxs","width":50} how do I directly capture the value? of url key
$me = $response->getGraphUser();
$pictureJson = $me->getPicture();
$pictureItem = json_decode($pictureJson,true);
echo $pictureItem['url'];probably converts this json string into a PHP array. And then deal with it.
