PHP arrayObject why cannot I access array keys using object notation?

Question

I'm trying to access array keys via object notation. I thought code below should work?

<?php

  $accountData = array('role'=> 'user');
  $accountDataAO = new ArrayObject($accountData, ArrayObject::STD_PROP_LIST);
  echo $accountDataAO->role;
?>

But I get this:

PHP Notice:  Undefined property: ArrayObject::$role in /home/stan/Desktop/test.php on line 5
PHP Stack trace:
PHP   1. {main}() /home/stan/Desktop/test.php:0

What am I doing wrong?

From php.net This class allows objects to work as arrays. ==> not arrays as objects. Eitherway, check the manual php.net/manual/en/class.arrayobject.php — AmazingDreams

ohh nvm. I figured it out. Had to add: ArrayObject::ARRAY_AS_PROPS — Dannyboy

@Dannyboy update your original question then in case anyone else searches for the same thing. — Styphon

For future reference, this is demonstrated on the ArrayObject::setFlags() manual page. — salathe

ahh. nvm. I had to add: ArrayObject::ARRAY_AS_PROPS

<?php
  $accountData = array('role'=> 'user');
  $accountDataAO = new ArrayObject($accountData, ArrayObject::STD_PROP_LIST | ArrayObject::ARRAY_AS_PROPS); 
  echo $accountDataAO->role;
?>
