#32670 [NEW]: foreach sets source variable if not already set and does not issue warning

From: cmoore at iyd dot com Operating system: Linux PHP version: 4.3.11 PHP Bug Type: Arrays related Bug description: foreach sets source variable if not already set and does not issue warning Description: ------------ prior versions of php (4.3.10 tested) will issue a warning if an unset variable is passed to foreach(). even with error_reporting(E_ALL), this one will not warn. the warning would be nice to see with the same level of error reporting that if() warns at. Reproduce code: --------------- <? error_reporting(E_ALL); foreach($check as $test) ; Expected result: ---------------- Warning: Invalid argument supplied for foreach() in test.php on line 3 Actual result: -------------- there is no result in 4.3.11 -- Edit bug report at http://bugs.php.net/?id=32670&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32670&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32670&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32670&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32670&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32670&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32670&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32670&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32670&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32670&r=support Expected behavior: http://bugs.php.net/fix.php?id=32670&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32670&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32670&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32670&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32670&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32670&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32670&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32670&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32670&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32670&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32670&r=mysqlcfg
