我想获得facebook组中每个墙贴的喜欢总数（如果有的话），但是正常的foreach循环似乎在Facebook \ GraphUser对象中不起作用。
if($session) {
try {
$user_profile = (new FacebookRequest(
$session, 'GET', '/{group_id}/feed'
))->execute()->getGraphObject(GraphUser::className());
foreach ($user_profile as $data) {
echo '<img src="'.$data['picture'].'"><br>';
if($data['likes']){
echo 'total likes for this photo is '.count($data['likes']['data']).'<br>';
}else{
echo 'no likes at the moment.<br>';
}
}
} catch(FacebookRequestException $e) {
echo "Exception occured, code: " . $e->getCode();
echo " with message: " . $e->getMessage();
}
}
以下是GraphUser对象供参考。任何想法如何循环这个？

进一步挖掘后，我终于得到了一个可行的答案来回答我自己的问题; - ）
$x = $user_profile->getProperty('data');
$y = $x->asArray();
