#33287 [NEW]: foreach does not give errors

From: chris at deskpro dot com Operating system: Win/MacOS linux untested PHP version: 4.3.11 PHP Bug Type: Arrays related Bug description: foreach does not give errors 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 bug report at http://bugs.php.net/?id=33287&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33287&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33287&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33287&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33287&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33287&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33287&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33287&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33287&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33287&r=support Expected behavior: http://bugs.php.net/fix.php?id=33287&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33287&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33287&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33287&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33287&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33287&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33287&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33287&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33287&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33287&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33287&r=mysqlcfg
