Summary: Do not keep last element treated by foreach
referenced
-Status: Open
+Status: Duplicate
Type: Feature/Change Request
Package: Scripting Engine problem
PHP Version: 5.3.8

Private report: N
New Comment:
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
