Can't access object variables in PHP from Facebook Graph API – Facebook api

I have a request to the Facebook Graph API that returns a post from a facebook account.

I am simply trying to access the data instance of the object returned in PHP but everything I have tried returns NULL.

Sample response

{
   "data": [
      {
         "id": " 111111111111111111100000",
         "message": "Coming soon #PERFECTFIT 05.07.17 👀nRegister to be one of the first to find out what it is here ⬇️nhttp://www.bathrugby.com/the-club/supporters/perfect-fit-register/",
         "created_time": "2017-06-26T17:39:20+0000",
         "link": "http://www.bathrugby.com/the-club/supporters/perfect-fit-register/",
         "full_picture": "https://scontent.xx.fbcdn.net/v/t39.2147-6/19284954_1592534984092755_4946207882807869440_n.jpg?oh=56cc96435f423cec31962966b6f689c2&oe=59DB08B6"
      }
   ]
}

I want to get at the array of objects data provides so I can MVC the data returned in a larger response.

This doesn’t currently work: 

$response->data; // returns null
$response[0]->data; // returns null
$response->data[0]; // returns null

Feel I’m missing something obvious.

    first decode it with json_decode then trying to access the data object 

    $res = json_decode($response);    
print_r($res->data);
print_r($res->data[0]->id);
print_r($res->data[0]->message);

    code

    you have to use first json decode function so you can get the data from the json response.

    $response = '{
  "data": [
  {
     "id": "143384725674462_1592535354092718",
     "message": "Coming soon #PERFECTFIT 05.07.17 👀nRegister to be one of the first to find out what it is here ⬇️nhttp://www.bathrugby.com/the-club/supporters/perfect-fit-register/",
     "created_time": "2017-06-26T17:39:20+0000",
     "link": "http://www.bathrugby.com/the-club/supporters/perfect-fit-register/",
     "full_picture": "https://scontent.xx.fbcdn.net/v/t39.2147-6/19284954_1592534984092755_4946207882807869440_n.jpg?oh=56cc96435f423cec31962966b6f689c2&oe=59DB08B6"
  }
 ]
 }';

$response = json_decode($response);

print_r($response->data[0]->id); 
print_r($response->data[0]->message);
