Note Submitter: stefan dot van dot beusekom at gmail dot com ---- Following is a recursive function that makes all the strings it finds safe for data entry. If the underlying value is an array, it will loop through that array as well, to inifity. So any array depth is allowed. This might come in handy when dealing with sessions, posts, gets or whatnot arrays, where you immediately want to make use of the data without having to filter the data first. <?php /* * Created by: Stefan van Beusekom * Created on: 31-01-2011 * Description: A method that ensures safe data entry, and accepts either strings or arrays.
