Using PHP5 Release and Zend Optimizer 2.5.3

---------------
<?
$arr = get_defined_vars();
print_r($arr);
?>

    [GLOBALS] => Array
        (
            [_POST] => Array
                (
                )
            [_GET] => Array
                (

            [_FILES] => Array
                (
