您可以通过传递如下参数来获取总数
?fields=likes.summary(1),comments.summary(1),
$fbtimeposts = (new FacebookRequest($session, 'GET', "/me/feed?fields=likes.summary(1),comments.summary(1),story,link,comments,likes,source,picture,type,status_type,application,message,message_tags,name,caption,actions,from,feed_targeting,full_picture,description,updated_time,created_time,id,object_id,parent_id,place,story_tags,targeting,with_tags&limit=10&date_format=U&limit=10&date_format=U"))->execute()->getGraphObject()->asArray();
我希望上面的例子对你有所帮助!!!!
