Convert Facebook decoded json to PHP array

Question

I have the following PHP code:

define('TOKEN_FILE', 'fb_page_accestoken.txt'); // dont need to change this
$fb = new Facebook(array( 
                  'appId' => FB_APP_ID,
                  'secret' => FB_APP_SECRET,
                  'cookie' => true,
));

$access_token = file_get_contents('fb_app_token.txt');

$response  = "https://graph.facebook.com/me/accounts?access_token=".$access_token;
$responsez = json_decode(file_get_contents($response ,true)); 
print_r($responsez);

When I use the above code I decode the JSON string and get the following:

stdClass Object ( [data] => Array ( [0] => stdClass Object ( [category] => Media/news/publishing [name] => PAGE ABC [access_token] => abcdefghijklmnopqrstuvwxyz1234567890 [perms] => Array ( [0] => ADMINISTER [1] => EDIT_PROFILE [2] => CREATE_CONTENT [3] => MODERATE_CONTENT [4] => CREATE_ADS [5] => BASIC_ADMIN ) [id] => 35645645678735 ) [1] => stdClass Object ( [category] => Entertainment website [name] => Page 123 [access_token] => abcdefghijklmnopqrstuvwxyz1234567890 [perms] => Array ( [0] => ADMINISTER [1] => EDIT_PROFILE [2] => CREATE_CONTENT [3] => MODERATE_CONTENT [4] => CREATE_ADS [5] => BASIC_ADMIN ) [id] => 1364564569777454 )

How can I get the above into a PHP array? For example to be able to extract the access_token of page id 1364564569777454.

$responsez->data[0]->id or responsez['data']['0']['id'] when $responsez = json_decode(file_get_contents($response), true) — Dave Chen

@DaveChen excellent it worked. Instead of having data[0] would it be possible to have its absolute name rather than its relatgive e.g. data['XYZ']? — user3173207

Do you mean this page name? [name] => PAGE ABC You'll want to do a loop, to return the array that has that specific attribute. — Dave Chen

Instead of having responsez['data']['0']['id'] one would have responsez['data']['XYZ']['id'] i.e. 0 instead of XYZ - something static — user3173207

responsez = json_decode(file_get_contents($response), true);

The second param in json_decode allow convert returned object into associative arrays.

 $arr = array();
 foreach($responsez->data as $obj){
      $arr[] = array("page_id"=>$obj->id,"access _token"=>$obj->access_token);         
 }
 print_r($arr);

I was having troubles with the accounts JSON and this worked better for me:

        $request = (new FacebookRequest($session, 'GET', '/' . $this->userID . '/accounts'))->execute();
        $graphObject = json_decode($request->getRawResponse(), true);

        foreach ($graphObject['data'] as $page) { // array['data', 'paging']
            if ($page['id'] == $this->fbAppPageID) {
                $this->pageToken = $page['access_token'];
            }
        }
        return $this->pageToken;
