PHP Bug Type: Arrays related
Bug description: copy-on-write error
Description:
------------
Altering a subindex of a copy of an array alters the original array as
well. Similar to bug#27381. Altering a root index does not exhibit this
behaviour.
Reproduce code:
---------------
<?php
$arr = array(1,2,3);
$arr["foo"] = array(4,5,6);
$copy = $arr;
unset($copy["foo"][0]);
print_r($arr);
?>
Expected result:
----------------
Array
(
[0] => 1
[1] => 2
[2] => 3
[foo] => Array
(
[0] => 4
[1] => 5
[2] => 6
)
)
Actual result:
--------------
Array
(
[0] => 1
[1] => 2
[2] => 3
[foo] => Array
(
[1] => 5
[2] => 6
)
)
