Global sanitation of user input in PHP
<p>I recently came across a post in a forum, where it was asked about implementing global sanitation of super globals such as $_GET, $_POST and the rest BEFORE it even enters the database.</p>

<p>What do you guys think of this method, as i was thinking of implementing this, cause there may be a time where i forget to do the proper sanitation.</p>

<p>I am also looking for a free class before making my own, but the one i found was for PHP 3.0.</p>

<p>Will <code>array_walk_recursive</code> do the job for my purpose?</p>
