Retrieving data from a Facebook GraphObject - php

Question

I have looked around and tried several things, converting it to array and trying to access the object directly.
I want to take out the page ID, name and access token.
Here is my code to get the object with the pages I look after:
$request = new FacebookRequest($session, 'GET', '/'.$userID .'/accounts');
$response = $request->execute();
$graphObject = $response->getGraphObject();
I get the following array using $array = (array) $graphObject;:
Array([*backingData] => Array(
[data] => Array(
[0] => stdClass Object(
[access_token] => CAAVOhgjThxcBAOZB61QxkxI1qdhZCngNZADQloUasFpTRCoZC7hYiDydjXQ9U0vQIjUMyZAeb6aGLKi7VE1btwk8eOPnsEzxyZPhJV1GVoujWlbb6PHo44yIi3D5VPSBRJJuNUOXobSgQNAevpSDZBgZDZD

)

)

I have edited the IDs and tokens here for public use.
I am sure I am just missing a next trick to get these values.

Answer 1

You can use the methods getProperty() and getPropertyAsArray() to get the values of a GraphObject. If you want to know what properties there are, use getPropertyNames().
Since this is an array of data (multiple pages the user is admin of), it might be easier to use it as a simple array, like you are trying to - there is a method called asArray() which does exactly this:
$graphObject = $response->getGraphObject();
$data = $graphObject->asArray();
Here's the reference for the Facebook GraphObject class: https://developers.facebook.com/docs/php/GraphObject/4.0.0

Answer 2

so i got a clue from the above answer and moved on:
my finished code was:
foreach ($data as $key => $value) {
if (is_array($value)) {
foreach ($value as $invalue) {
$array = (array) $invalue;
foreach ($array as $key2 => $value2) {
if ($key2=='access_token') {
$c++;
$ats[$c]=$value2;
}
if ($key2=='name') {
$pagenames[$c]=$value2;
}
if ($key2=='id') {
$ids[$c]=$value2;
}
}
}
}
}
So i got a nice clean array from $data = $graphObject->asArray();
then proceeded.
There was another object inside the array so i typecast that to array then run foreach loops over it to get the keys i wanted.
Not the prettiest but it did the job.
thanks
