从Facebook Graph Object获取属性

Question

I am using facebook api with PHP to get comments on a specific post by postID

$request = new FacebookRequest(
$sess,
 'GET',
  '/xxxxxxxxxxxxxxxxxxxxxx/comments'
  );
   $response = $request->execute();
   $graphObject = $response->getGraphObject();

the result when i do it with graph api is a file like that

{
 "data":[
 {
  "id": "xxxxxxxxxxxxxxxxxxxxx",
  "from": {
    "id": "yyyyyyyyyyyyy",
    "name": "someName"
  },
  "message": "commentMessage",
  "can_remove": true,
  "created_time": "2014-12-06T18:05:03+0000",
  "like_count": 0,
  "user_likes": false
}
],
"paging": {
"cursors": {
  "after": "WTI5dGJXVnVkRjlqZFhKemIzSTZNVFUwTURJMU56Z3dPVFUxTkRjME1qb3hOREUzT0RnNU1UQXpPaTB4",
  "before": "WTI5dGJXVnVkRjlqZFhKemIzSTZNVFUwTURJMU56Z3dPVFUxTkRjME1qb3hOREUzT0RnNU1UQXpPaTB4"
}
}
}

the response graph object doesn't match any type of graphObject subclass.

i have tried:

   $graphObject['data'][0]['from']['name']

but the graph object is not an array

how can i get the attributes such as name or message from the $graphObject

Answer 1

$object = $response->getGraphObject();

// User example

echo $object->getProperty('name'); echo $user->getName();

// Location example

echo $object->getProperty('country'); echo $loc->getCountry();
