Summary: array_merge() does only merge references of objects

No bug here. Object variables have an extra level of indirection (they're
object references). This is the general behavior of the language and doesn't
require a special mention in array_merge.

Description:
------------
I'm not sure, if this is a bug or a desired behaviour that is not mentioned in
the docs. When merging an array with itself with array_merge() then modifiying
one array element afterwards does also affect all other elements.
If it's intentional, then it should be mentionend in the documentation.
Test script:
---------------
<?php
$items = array();
$items[] = (object) array(
'year' => 2012,
'desc' => 'something happens'
);
$many = array_merge($items, $items);
print_r($many);
$many[0]->year = 2040;
print_r($many); // changes also year of $many[1]
Expected result:
----------------
$many[0]->year should be 2040
$many[1]->year should be 2012
Actual result:
--------------
$many[0]->year is 2040
$many[1]->year is 2040
