Edit report at https://bugs.php.net/bug.php?id=55801&edit=1 ID: 55801 Updated by: pajoye@php.net Reported by: mapi at pdepend dot org Summary: Behavior of unserialize has changed -Status: Open +Status: Feedback Type: Bug Package: Variables related Operating System: Linux (Fedora 15) PHP Version: 5.4.0beta1 Block user comment: N Private report: N New Comment: Is it about objects being serialized and stored using 5.3 and unserialized using 5.4? And it fails to unserialize them? Or are you doing this proecess manually? Previous Comments: ------------------------------------------------------------------------ [2011-09-27 20:06:13] mapi at pdepend dot org Description: ------------ There is a regression or change in how object structures are serialized or unserialized in PHP's 5.4.x branch. I am sorry that I cannot give a more detailed explanation and say what has changed and causes this issue, but an object cache for one of my applications fails with all PHP 5.4.x version, while it works with all PHP 5.2.x and PHP 5.3.x versions. I would expect that this behavior change would also affect other applications or libraries that utilize PHP's (un)serialize functions.
