When using same variable with reference and without reference in foreach
works incorrectly.

[7, 8, 9]
];
foreach($data as $k => &$v) {
rsort($v);
}
foreach($data as $k => $v) {
print_r($v);
}
Expected result:
----------------
Array
(
[0] => 3
[1] => 2
[2] => 1
)
Array
(
[0] => 6
[1] => 5
[2] => 4
)
Array
(
[0] => 6
[1] => 5
[2] => 4
)
Actual result:
--------------
Array
(
[0] => 3
[1] => 2
[2] => 1
)
Array
