Bug #55801 [NEW]: Behavior of unserialize has changed

From: Operating system: Linux (Fedora 15) PHP version: 5.4.0beta1 Package: Variables related Bug Type: Bug Bug description:Behavior of unserialize has changed 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.
