How is your data being stored? Is it a single text value? Is it a lot of join records spanning multiple tables? Depending on your answer you're going to have to handle things quite differently. Duplicating a single record is much easier. Text based revisions are a bit different than a HTML revision too. With HTML all sorts of code changes could have happened without a single visual change. In that case should you really show the user a difference? It depends on your target. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
