#33243 [NEW]: ze1_compatibility_mode does not work as expected

From: ladislav dot prosek at matfyz dot cz Operating system: Windows XP SP2 PHP version: 5.0.4 PHP Bug Type: Zend Engine 2 problem Bug description: ze1_compatibility_mode does not work as expected Description: ------------ When zend.ze1_compatibility_mode is On, object copying is not compliant to PHP4. Namely, objects are not deep-copied on assignment. This may cause substantial problems to legacy applications that rely on the compatibility mode. Reproduce code: --------------- $a->y->z = 0; $b = $a; // should perform deep copy of $a $b->y->z = 1; // hence this should have no effect on $a var_dump($a); Expected result: ---------------- object(stdClass)#1 (1) { ["y"]=> object(stdClass)#2 (1) { ["z"]=> int(0) // <-- } } Actual result: -------------- object(stdClass)#1 (1) { ["y"]=> object(stdClass)#2 (1) { ["z"]=> int(1) // because $a->y and $b->y are still one object after the assignment } } -- Edit bug report at http://bugs.php.net/?id=33243&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33243&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33243&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33243&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33243&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33243&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33243&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33243&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33243&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33243&r=support Expected behavior: http://bugs.php.net/fix.php?id=33243&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33243&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33243&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33243&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33243&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33243&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33243&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33243&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33243&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33243&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33243&r=mysqlcfg
