This is not a duplicate of any of the reports indicated. The reports indicated are reports of
application bugs as PHP bugs, which are therefore invalid. This report is asking to change PHP, in
order to avoid such application bugs.

This has previously been discussed and rejected, due to users relying both on
PHP's lack of block scope and foreach's by-reference syntax. (Sometimes both at
once, unfortunately.)
Duplicate of bug #29992, bug #47388, bug #54189, bug #50485, and probably a bunch
of others.

Please fix this. It creates a lot of hard to debug bugs.

Description:
------------
As explained on http://ca.php.net/manual/en/control-structures.foreach.php
:
Warning
Reference of a $value and the last array element remain even after the foreach loop. It is
recommended to destroy it by unset().
In my opinion, PHP shouldn't keep the last element referenced by default, but at least, please
provide a syntax which will not keep it. The current situations causes bugs like https://bugs.php.net/bug.php?id=49386
