Bug description:  Addition of Magic __toArray() function

Description:
------------
Doing this:

$newarray = (array)$object;

will take the properties of an object and assign them as the values of
keys in an array.

As of PHP 5.2, doing this:

$stringified = (string)$object;

will call the magic __toString() function for a user-specified formatting
of the object as a string.

It would be a great addition to call a magic __toArray() function if an
object is cast as an array, instead of converting its public members to
array elements.  (For instance, the class might not have public members). 
Classes without the function could use the default method of mapping
property names to array keys.

Just my two cents.

Reproduce code:
---------------
<?php

class magicExample 
{
    public $aoeu = "htns";

    function __toArray()
    {
        return array('foo'=>'bar');
    }
}

$test = new magicExample();
$array = (array)$test;

print_r($array); // should show foo=>bar, not aoeu=>htns

?>
