Detecting rude/swear/dirty words

[Anon]

Does anyone know of a good script (preferably PHP) that detects rude/swear/dirty words in form input?

I know I could add all the ones I can think of to a database table and then check the form input against that table. The problem is that some are sure to get through.

Has anyone tackled this problem before?

Cheers

THe way I do this in perl is to set up an array with "Dictionary words". You do a compare of each element against the dictionary. Like a foreach loop.
