Description:
------------
When using a combination of array_map() & strip_tags to create a localized copy of the $_POST superglobal array I am experiencing problems if $_POST contains a nested array.

It seems to discard any secondary iteration of said nested array.

Test script:
---------------
$_POST = array('level-1-1', $var1,
               'level-1-2', $var2,
               'level-1-3', $var3,
               'level-1-4', array('level-2-1', $var1,
                                  'level-2-2', $var2,
                                  'level-2-3', $var3),
               'level-1-5', $var5);

$post = array_map(strip_tags, $_POST);

echo '<pre>'; print_r($post); echo '</pre>';

/* I am left with this?
level-1-1 => $var1
level-1-2 => $var2
level-1-3 => $var3
level-1-5 => $var5
*/

Expected result:
----------------
I expected a complete copy of the nested superglobal $_POST.

Actual result:
--------------
Any nested array information is getting stripped out.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

this call strip_tags in a way similar to this:


strip_tags(array('level-2-1', $var1,
                                  'level-2-2', $var2,
                                  'level-2-3', $var3));

which gives an unexpected result.

what you need is wrapper handling the recusrion similar to

function strip_tags_recursive($data) {
     if (is_array($data)) {
         return array_map('strip_tags_recursive', $data);
     } else {
         return strip_tags($data);
     }
}

$myget = strip_tags_recursive($_GET);

While all this isuntested but shouldgive you the idea.

Thanks. I suppose I thought array_map should work recursively.
