This is duplicate of bug #25359.
Behavior is different but reason exactly the same.

references.

Description:
------------
Using array_multisort() in a function with copy of local array, this
affects the original array.
It's same to bug #32031
I solve this changing the code:
$arrSort = $arr;
to:
$arrSort = $arr + array();
Reproduce code:
---------------
function bug_array($arr) {
$arrSort = $arr;
array_multisort($arrSort);
}
$arr = array(1, 0);
print_r($arr);
bug_array($arr);
print_r($arr);
Expected result:
----------------
Array
(
[0] => 1
[1] => 0
)
Array
(
[0] => 1
[1] => 0
)
Actual result:
--------------
Array
(
[0] => 1
[1] => 0
)
Array
(
[0] => 0
[1] => 1
)
