Bug description: function changes the internal pointer of its array parameter
Description:
------------
The function which is supposed to get a copy of the original array and
never mess the original array magically changed the internal pointer of the
original array. Noticed it doesn't change the pointer if foreach just loop
though the array itself (this seems to be fixed in #40705). However, as it
is in the repro code, I loop though a subelement of the array, it still
changes the pointer.
Reproduce code:
---------------
<?php
function a($arr)
{
foreach($arr['k'] as $r)
{
}
}
$arr = array(
'k' => array(1)
);
a($arr);
var_dump(current($arr['k']));
Expected result:
----------------
int(1)
Actual result:
--------------
bool(false)
