How do I get the data out of this array? Single sign on

Question

I have implemented a Single Sign on function using Janrain. It outputs this data (amongst other data). Is it possible to break this down and extract only the displayName for example so that I may place it in a variable?

auth_info:
array(3) {
  ["stat"]=>
  string(2) "ok"
  ["profile"]=>
  array(10) {
    ["providerName"]=>
    string(8) "Facebook"
    ["identifier"]=>
    string(48) "removed"
    ["preferredUsername"]=>
    string(10) "OllieJones"
    ["displayName"]=>
    string(11) "Ollie Jones"
    ["name"]=>
    array(3) {
  ["formatted"]=>
  string(11) "Ollie Jones"
  ["givenName"]=>
  string(5) "Ollie"
  ["familyName"]=>
  string(5) "Jones"
}

Here is the script that creates it and where I would like to define the variable https://github.com/janrain/Janrain-Sample-Code/blob/master/php/rpx-token-url.php

Many Thanks
