html filtering

Does anyone know of a PHP function or class that will take user input and strip out all html tags except the A tags, IMG tags or others that I permit?

I am working on a simple bulletin board type system and I want to allow users to post links and images, but not scripts, tables or other things I deem unworthy.

Such code must surly exist. I am hoping to not spend time re-inventing the wheel here.

strip_tags() is what you're looking for. Read about it here: http://us2.php.net/strip_tags

As you can see, in the optional second parameter, you can specify which tags you want the function to leave alone. Good luck!
