I have PHP configured so that magic quotes are on and register globals are off.

I do my best to always call htmlentities() for anything I am outputing that is derived from user input.

I also occasionally seach my database for common things used in xss attached such as...

<script

What else should I be doing and how can I make sure that the things I am trying to do are always done.
