Bug #69072 [NEW]: bug when serializing classes that implements Serializable interface

From: quamis+php at gmail dot com Operating system: Linux PHP version: 5.6.5 Package: Class/Object related Bug Type: Bug Bug description:bug when serializing classes that implements Serializable interface Description: ------------ Consider the following example: class A implements Serializable, defines serialize() as a serialized stdClass class B extends A, adds 1 public member index.php instantiates B and serializes it to be able to cache it/store it for future reference. function serialize fails in this case, returns an invalid string. It should at least issue an exception/warning. If class A defines serialize() as a serialized array it will work as expected. Test script: --------------- Testcase: http://pastebin.com/6Hc60VbD , http://3v4l.org/SggeU Working testcase (class A returns serialized array): http://pastebin.com/itzZY1En , http://3v4l.org/hIJE9 Expected result: ---------------- no exception should be thrown, and an actual representation of the class should be generated. According to http://3v4l.org, this woked ok in PHP 5.3, and its broken since PHP 5.4 -- Edit bug report at https://bugs.php.net/bug.php?id=69072&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69072&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69072&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69072&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69072&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69072&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69072&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69072&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69072&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69072&r=support Expected behavior: https://bugs.php.net/fix.php?id=69072&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69072&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69072&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69072&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69072&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69072&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69072&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69072&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69072&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69072&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69072&r=mysqlcfg
