#46416 [NEW]: each() erratic behaviour with objects

From: bugzilla at zuavra dot net Operating system: Windows XP, but probably irrelev PHP version: 5.3.0alpha2 PHP Bug Type: Scripting Engine problem Bug description: each() erratic behaviour with objects Description: ------------ Using each() to iterate through an object will produce weird results in two respects: 1. It will expose private and protected members alongside public ones. 2. For private and protected members, the keys (names) are jumbled. Yes, I know that this behaviour is known and that the manual page for each() warns about this. But such an inconsistency should not exist. Desirable consistent behaviour: a) Produce the same results as foreach() (show only public members). or b) Refuse to work with objects altogether and state so in the manual. Reproduce code: --------------- <?php class Example { private $priv = 1; protected $prot = 2; public $pub = 3; } $obj = new Example(); while (list($key, $val) = each($obj)) { printf("%s = %s\n", $key, $val); } ?> Expected result: ---------------- pub = 3 Actual result: -------------- [NUL]Example[NUL]priv = 1 [NUL]*[NUL]prot = 2 pub = 3 where [NUL] is the null (0x00) character -- Edit bug report at http://bugs.php.net/?id=46416&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46416&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46416&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46416&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46416&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46416&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46416&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46416&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46416&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46416&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46416&r=support Expected behavior: http://bugs.php.net/fix.php?id=46416&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46416&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46416&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46416&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46416&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46416&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46416&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46416&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46416&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46416&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46416&r=mysqlcfg
