The same thing using the stdclass works fine. Test script: ------------ <?php $Object = (object)array( 'a' => 1, 'b' => &$Object, ); print_r($Object); $Array = array( 'a' => 1, 'b' => &$Array, ); print_r($Array); $Array = unserialize(serialize($Array)); $Object = unserialize(serialize($Object)); $Object->b->a = 2; print_r($Object); $Array['b']['a'] = 2; print_r($Array); ?> Actual result: -------------- stdClass Object ( [a] => 1 [b] => stdClass Object *RECURSION* ) Array ( [a] => 1 [b] => Array ( [a] => 1 [b] => Array *RECURSION* ) ) stdClass Object ( [a] => 2 [b] => stdClass Object *RECURSION* ) Array ( [a] => 1 [b] => Array ( [a] => 2 [b] => Array *RECURSION* ) ) ------------------------------------------------------------------------ [2010-08-04 22:03:08] martin dot leucht at googlemail dot com Okay, I finally made it though. I setup a build environment, built the latest dev-version of PHP and ran the test script. But still: identical results. Please tell me how can I provide some help or assistence to solve this issue?! ------------------------------------------------------------------------ [2010-08-03 13:23:39] martin dot leucht at gmail dot com Sorry, but there are no builds on the Windows snapshots page and as I do not maintain a PHP build environment (nor am currently willing to do so due to a lack of time) I can not test it right now. Could you please give me a hint when the snapshot builds are available or if anyone else can do this test using the given test script above. ------------------------------------------------------------------------ [2010-08-03 09:53:39] mike@php.net Please try using this snapshot: http://snaps.php.net/php-trunk-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Could you please try a trunk snapshot, IIRC this problem might be fixed already. Thanks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
