Description:
------------
Exmaple 21-3 "References with complex arrays" as available on http://www.php.net/manual/en/language.references.whatdo.php is not correct, at least not for PHP version 5.2.0.

The example claims to "not work as expected". But it does work as expected (and contrary to the documented results). Also, even if the example did "not work as expected", there is no explanation for why it is not supposed to work, other than stating that complex arrays "sometimes" (?!?) are copied.

Reproduce code:
---------------
<?php
// taken directly from Example 21-3
$top = array(
   'A' => array(),
   'B' => array(
       'B_b' => array(),
   ),
);

$top['A']['parent'] = &$top;
$top['B']['parent'] = &$top;
$top['B']['B_b']['data'] = 'test';
print_r($top['A']['parent']['B']['B_b']); // array()
?> 

Expected result:
----------------
According to the documentation:

array()



Actual result:
--------------
Array
(
    [data] => test
)
