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.. Previous Comments: ------------------------------------------------------------------------ [2007-08-16 12:11:34] steven dot mccoy at miru dot hk 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. ------------------------------------------------------------------------ [2007-08-16 11:52:54] [EMAIL PROTECTED] 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? ------------------------------------------------------------------------ [2007-08-16 11:46:15] [EMAIL PROTECTED] See also bug #42303 ------------------------------------------------------------------------ [2007-08-13 21:34:06] crrodriguez at suse dot de Workaround : use array_udiff with a supplied callback function or use only arrays. ------------------------------------------------------------------------ [2007-08-12 06:54:01] steven dot mccoy at miru dot hk Reproduced with the Win32 CVS build: PHP 5.2.4RC1-dev (cli) (built: Aug 12 2007 00:04:25) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
