New Comment:
So what? each() is not touching the $items array, it is touching the
$items [0], and $items [1] elements which are arrays as well.

http://php.net/each
each -- Return the current key and value pair from an array and
*advance the array cursor*

In my previous comment I meant that no array elements are being
added/removed. Besides try removing the each() operator and behaviour
becomes correct. Something that should not happen.

The array is not being modified.

Do not modify array in the foreach() loop.

Description:
------------
When using foreach($arr as $index => &$item), the $item reference does
not always allow a modification of the referenced element.
Reproduce code:
---------------
<?
$items = array (array (1), array (1));
foreach ($items as $index => &$one_item) {
printf ("C1 IDENTICAL: %u\n", $items [$index] === $one_item);
each ($items [$index]);
printf ("C2 IDENTICAL: %u\n", $items [$index] === $one_item);
$one_item = 678;
printf ("C3 IDENTICAL: %u\n", $items [$index] === $one_item);
}
?>
Expected result:
----------------
C1 IDENTICAL: 1
C2 IDENTICAL: 1
C3 IDENTICAL: 1
C1 IDENTICAL: 1
C2 IDENTICAL: 1
C3 IDENTICAL: 1
Actual result:
--------------
C1 IDENTICAL: 1
C2 IDENTICAL: 1
C3 IDENTICAL: 1
C1 IDENTICAL: 1
C2 IDENTICAL: 1
C3 IDENTICAL: 0
