The problem still persist. Using the example now the results are:

$parameters key before foreach: a
$parameters key after foreach: b
$parameters key before foreach: b
$parameters key after foreach: b

and not the expected results:

$parameters key before foreach: a
$parameters key after foreach: a
$parameters key before foreach: a
$parameters key after foreach: a

Description:
------------
In PHP 5.2.4 when I set array values inside a foreach, the array
pointer is moved to the second element of the array or, better, to the
element after the first modified element of the array.

In PHP 5.2.3 the array pointer was not moved.

Moreover this does not happen if i assign the array elements outside
the foreach.

Reproduce code:
---------------
$parameters = array(
        'a' => 1,
        'b' => 2,
        'c' => 3,
        'd' => 4
);
echo "\$parameters key before foreach: " . key($parameters) . "\n";
foreach($parameters as $key => $value) {
        $parameters[$key] = "s" . $value;
}
echo "\$parameters key after foreach: " . key($parameters) . "\n";

echo "\$parameters key before foreach: " . key($parameters) . "\n";
$parameters['a'] = "s" . 1;
$parameters['b'] = "s" . 2;
$parameters['c'] = "s" . 3;
$parameters['d'] = "s" . 4;
echo "\$parameters key after foreach: " . key($parameters) . "\n";


Expected result:
----------------
$parameters key before foreach: a
$parameters key before foreach: a

$parameters key before foreach: a
$parameters key before foreach: a

Actual result:
--------------
$parameters key before foreach: a
$parameters key before foreach: b

$parameters key before foreach: a
$parameters key before foreach: a
