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
