I used to do that, but it becomes impossible to distinguish between 0 and null. Which is okay until you inherit a database with zeros as keys. Maybe: $page_index = isset($_GET['page']) ? intval($_GET['page']) : null; This is will not produce any strict errors, but if page='hello' then $page_index is 0. I would rather it be null in that case. If php's '||' operator wasn't so stupid, we could use constructs like: $page_index = intval($_GET['page']) || null; Auto casting with || and && is on my top 10 list of things I hate about php. -john campbell _______________________________________________ New York PHP Community Talk Mailing List http://lists.nyphp.org/mailman/listinfo/talk NYPHPCon 2006 Presentations Online http://www.nyphpcon.com Show Your Participation in New York PHP http://www.nyphp.org/show_participation.php
