Bug description: Problem using arrays and value references
Description:
------------
Using a foreach loop to edit values by reference in an array will mangle
the array. From testing seems the last item in the array will be
replaced by the second last item. It seems the problem shows once the
array has been traversed start to end.
The code to reproduce the problem does a much better job describing the
issue.
Reproduce code:
---------------
<?php
$list = array('one', 'two', 'three', 'four');
foreach ($list as &$item) {
$item = "Row $item";
}
print_r($list);
foreach ($list as $index => $item) {
printf("Item #%u: %s\n", $index, $item);
}
print_r($list);
?>
Expected result:
----------------
Array
(
[0] => Row one
[1] => Row two
[2] => Row three
[3] => Row four
)
Item #0: Row one
Item #1: Row two
Item #2: Row three
Item #3: Row four
Array
(
[0] => Row one
[1] => Row two
[2] => Row three
[3] => Row four
)
Actual result:
--------------
Array
(
[0] => Row one
[1] => Row two
[2] => Row three
[3] => Row four
)
Item #0: Row one
Item #1: Row two
Item #2: Row three
Item #3: Row three
Array
(
[0] => Row one
[1] => Row two
[2] => Row three
[3] => Row three
)
