Description:
------------
if we iterate over $_GET using references (see the example) and pass
$_GET to a function, function modifies $_GET and not the local copy.
For example, save the example code in test.php and open

test.php?mykey=foo
.

Reproduce code:
---------------
<?php
                function doit($http_get_params)
                {
                        $http_get_params['mykey'] = 'bar';
                        echo '<br/>'.$_GET['mykey'];
                }

                foreach($_GET as $key => &$value) {}

                echo '<br/>'.$_GET['mykey'];
                doit($_GET);
                echo '<br/>'.$_GET['mykey'];
?>


Expected result:
----------------
When we open test.php?mykey=foo I expect to see
foo
foo
foo

Actual result:
--------------
When we open test.php?mykey=foo we actually see
foo
bar
bar
