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
