Bug description: Bad problems with backported foreach() patch
Description:
------------
I've been a PHP developer for years and I don't remember such a big bug
introduced in a stable production release.
The foreach() patch backported from PHP5 broke down many sites that I run
and which use proprietary optimizers.
You should definitely remember what "stable" and "production" words mean,
and keep fun for PHP5.
P.S.: The bug is indeed in the optimizer, but this doesn't allow you to
make these kind of changes.
Reproduce code:
---------------
this is just explanative, the bug can be shown only with the proprietary
optimizer.
$a = array(array("a", "b"), array("a", "b"));
foreach ($a as $ax) { var_dump($a); }
Expected result:
----------------
obvious.
Actual result:
--------------
scratched array.
