I was sure that arrays are passed to functions by value, not by
reference. It looks like by-reference iteration changes array not only
isnide foreach statement, but array remains changed even after
iteration.

Description:
------------
I was sure that arrays are passed to functions by value, not by
reference. It looks like after by-reference iteration changes array not
only isnide foreach statement, but array remains changed even after
iteration.
Test script:
---------------
<?php
$a = array(1,2,3,4);
function myf($a,$k){
$a[$k] = 9;
}
foreach ($a as $k => &$v) {
myf($a, $k);
}
//myf($a, 3);
var_dump($a);
die();
Expected result:
----------------
array
0 => int 1
1 => int 2
2 => int 3
3 => int 4
Actual result:
--------------
array
0 => int 9
1 => int 9
2 => int 9
3 => &int 9
