I'd do something like this, so as to preserve the original post data
array:
$data = Array();
foreach($_POST as $key => $value)
{
$data[$key] = strip_tags($value);
}
Note that strip_tags() will not be able to decently clean up messy code
(i.e. code where the opening or closing tags themselves aren't formed
properly)
