Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.
See bug #25359 (same reason: reference)

Description:
------------
Seems, that multidimensional arrays are copied with one dimension,
which contains references to other included arrays.
I haven't found any references in manual, so this must be a bug.
Reproduce code:
---------------
<?php
$a[0]['id'] = array(22, 12, 33, 55);
$a[0]['secid'] = array("a","b","c","d");
print_r($a);
$b = $a;
foreach ($b as $k => $v) {
array_multisort($v['id'], SORT_DESC, $v['secid'], SORT_DESC);
}
print_r($a);
?>
Expected result:
----------------
Array
(
[0] => Array
(
[id] => Array
(
[0] => 22
[1] => 12
[2] => 33
[3] => 55
)
[secid] => Array
(
[0] => a
[1] => b
[2] => c
[3] => d
)
)
)
Array
(
[0] => Array
(
[id] => Array
(
[0] => 22
[1] => 12
[2] => 33
[3] => 55
)
[secid] => Array
(
[0] => a
[1] => b
[2] => c
[3] => d
)
)
)
Actual result:
--------------
Array
(
[0] => Array
(
[id] => Array
(
[0] => 22
[1] => 12
[2] => 33
[3] => 55
)
[secid] => Array
(
[0] => a
[1] => b
[2] => c
[3] => d
)
)
)
Array
(
[0] => Array
(
[id] => Array
(
[0] => 55
[1] => 33
[2] => 22
[3] => 12
)
[secid] => Array
(
[0] => d
[1] => c
[2] => a
[3] => b
)
)
)
