Description:
------------
next() misbehaves:
it does not increment the internal position pointer with PHP 4.4.1

Reproduce code:
---------------
<?php
$test = array();
for ($i = 0; $i < 10; $i++) {
    $test[] = $i;
}
while (next($test)) {
    echo current($test) . "<br />";
}
?>


Expected result:
----------------
1
2
3
4
5
6
7
8
9

Actual result:
--------------
1
1
