"When the ArrayObject refers to an object an array of the public properties of that object will be returned."

This description does not seem to be right:

<?php
class A
{
    public
$var = 'var';
    protected
$foo = 'foo';
    private
$bar = 'bar';
}

$o = new ArrayObject(new A());
var_dump($o->getArrayCopy());

/*
Dumps:

array(3) {
  ["var"]=>
  string(3) "var"
  ["*foo"]=>
  string(3) "foo"
  ["Abar"]=>
  string(3) "bar"
}
*/
?>

So it does not only include the public properties.

If you did something like this to make your constructor multidimensional capable you will have some trouble using getArrayCopy to get a plain array straight out of the method:
<?php
public function __construct( $array = array(), $flags = 2 )
{
   
// let’s give the objects the right and not the inherited name
   
$class = get_class($this);

    foreach(
$array as $offset => $value)
       
$this->offsetSet($offset, is_array($value) ? new $class($value) : $value);

   
$this->setFlags($flags);
}
?>

That’s the way I solved it:

<?php
public function getArray($recursion = false)
{
   
// just in case the object might be multidimensional
   
if ( $this === true)
        return
$this->getArrayCopy();

    return
array_map( function($item){
        return
is_object($item) ? $item->getArray(true) : $item;
    },
$this->getArrayCopy() );
}
?>

Hope this was useful!
