strip_tags() is a rather worthless function, if you ask me. It strips such evil code as <grin> or anything else surrounded by < and >. It's "allowed tags" attribute is misleading, also. You can think you're safe by allowing <b> tags, but I can include onmouseover (or any other) events to trigger javascript and XSS attacks. You're better to roll your own solution or just run everything through htmlentities()/htmlspecialchars() and show the user exactly what they typed. I'm on a crusade against the use of strip_tags(), if you haven't figured that out yet. :) ---John Holmes...
