Description:
------------
This might be related to bug 41221, upgrading from PHP 5.1.6-1 (Debian)
to 5.2.1 (Ubuntu) created a regression in handling output of JSON
decoding.

Does this mean that I can only use arrays ( json_decode($json, true) ),
and have to update all code appropriately?

Reproduce code:
---------------
<?php
$array = array(
                "first" => array(array("second" => 2), "two",
"three"),
                );
$json = json_encode($array);
$obj = json_decode($json);
var_dump(array_diff($array,$obj->first));
?>


Expected result:
----------------
array(1) {
  ["first"]=>
  array(3) {
    [0]=>
    array(1) {
      ["second"]=>
      int(2)
    }
    [1]=>
    string(3) "two"
    [2]=>
    string(5) "three"
  }
}


Actual result:
--------------
Catchable fatal error: Object of class stdClass could not be converted
to string in /tmp/- on line 7
