Submit form that only strips out harmful code but nothing else?

[Jason28]

I can write this up myself but was wondering if there was a script that allows users to use html in a submit form but prevents danagerous code from being entered?  Thanks.

Hmm well I meant just some simple codes that allows a user to submit html to a DB but nothing malicious so that it will appear on their page.  I could create an array and use preg matches and stuff but I was hoping to save time by finding a little script that does this for me.  Thanks.

 

EDIT

 

Actually I may try to use htmlspecialchars_decode() for the first time with htmlspecialchars to see how that turns out.
