Description:
------------
php-manual "Backward Incompatible Changes" did not describe changes with arrays internal pointers.
If I passed array to some function call_func($some_array)
internal pointer of $some_array reseted in php4, but saved in php5

Reproduce code:
---------------
$a = array (
  'first' => 1,
  'second' => 2,
);

function test($a) {
    while (list($k, $v)=each($a))
        echo $k."\n";
}

next($a);
test($a);

Expected result:
----------------
first
second

Or make in documented in "PHP: Backward Incompatible Changes"

Actual result:
--------------
In php4:
first
second

php5:
second
