New Comment:
Okay, so you think array_diff() is broken. As our bug system sucks,
can't edit original comment, etc. so please, open new short report about
the array_diff issue. (this one is a bit confusing with the json stuff
and all) And make sure the new report does not have any references to
JSON. :D

Well its either json_decode not making stdClass objects friendly for
comparison or array_diff() that broke. Lets try the latter then.

So this has nothing to do with JSON? Please reclassify if that is true
and fix the summary to contain what the bug is really about..

The situation I'm using it in is where the browser sends an array of
objects to PHP. The PHP scripts uses PEAR::DB_DataObject to generate an
array of objects inside a database table, I then use
array_diff/array_udiff to calculate what is new, what has changed, and
what should be deleted. The array_diff for items that have not changed
fails in 5.2 because PHP fails be able to compare some of the stdClass
objects.
$new_products = array_filter($products,
array('Order','is_new_product'));
debug('new_order_products: '.count($new_products).' found');
$old_products = array_diff($new_products, $products);
debug('old_order_products: '.count($old_products).' calculated');
$updated_products = array_udiff($old_products, $current_products,
array('Order', 'product_compare'));
debug('updated_order_products: '.count($updated_products).' found');
$deleted_products = array_udiff($current_products, $products,
array('Order', 'product_compare_by_id'));
debug('deleted_order_products: '.count($deleted_products).' found');
PEAR::DB_DataObject returns table rows as objects, the PHP JSON module
defaults to objects, but can include arrays of objects as shown
previously.
As a workaround I rebuilt PHP 5.1.6 from Ubuntu 6.10 on 7.04. If
someone can provide a array_udiff function that can compare objects like
before that would be great :-)
If the current circumstances are not clear, I will repeat: PHP 5.1.6
generates the expected result output as shown, PHP 5.2 does not.

Here's what I get for the encode:
{"first":[{"second":2},"two","three"]}
So actually you have another object inside the first, here's
var_dump($obj);
object(stdClass)#1 (1) {
["first"]=>
array(3) {
[0]=>
object(stdClass)#2 (1) {
["second"]=>
int(2)
}
[1]=>
string(3) "two"
[2]=>
string(5) "three"
}
}
And using json_decode($json, true):
array(1) {
["first"]=>
array(3) {
[0]=>
array(1) {
["second"]=>
int(2)
}
[1]=>
string(3) "two"
[2]=>
string(5) "three"
}
}
So what's the bug?
