#31251 [NEW]: Bad problems with backported foreach() patch

From: giovanni at giacobbi dot net Operating system: Linux PHP version: 4.3.10 PHP Bug Type: Unknown/Other Function Bug description: Bad problems with backported foreach() patch Description: ------------ I've been a PHP developer for years and I don't remember such a big bug introduced in a stable production release. The foreach() patch backported from PHP5 broke down many sites that I run and which use proprietary optimizers. You should definitely remember what "stable" and "production" words mean, and keep fun for PHP5. P.S.: The bug is indeed in the optimizer, but this doesn't allow you to make these kind of changes. Reproduce code: --------------- this is just explanative, the bug can be shown only with the proprietary optimizer. $a = array(array("a", "b"), array("a", "b")); foreach ($a as $ax) { var_dump($a); } Expected result: ---------------- obvious. Actual result: -------------- scratched array. -- Edit bug report at http://bugs.php.net/?id=31251&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31251&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31251&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31251&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31251&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31251&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31251&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31251&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31251&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31251&r=support Expected behavior: http://bugs.php.net/fix.php?id=31251&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31251&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31251&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31251&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31251&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31251&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31251&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31251&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31251&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31251&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31251&r=mysqlcfg
