ID: 33287 Updated by: tony2001@php.net Reported By: chris at deskpro dot com -Status: Open +Status: Feedback Bug Type: Arrays related Operating System: Win/MacOS linux untested PHP Version: 4.3.11 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Previous Comments: ------------------------------------------------------------------------ [2005-06-09 22:11:40] chris at deskpro dot com Description: ------------ This is a repost of 33264 33264 was closed because it was said the bug is the same as 31114. They are however completly different. 31114 is about foreach where the $key and $value are the same: foreach ($array AS $key => $key) which should, perhaps issue a warning. However, 33264 is about foreach not issuing an error when you try and loop on an unset variable or a string e.g.: $array = ''; foreach ($array AS $value) { this should, and used to issue an error (I think it was fatal). It not longer does. The manual even suggests this error is not preventable with a @, but not it dosen't appear at all. So this is both a real bug and important. Reproduce code: --------------- <?php error_reporting(E_ALL); foreach ($a AS $b) { } ?> Expected result: ---------------- Error about $a not being an array. Actual result: -------------- No error. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33287&edit=1
