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.
