title: php form curse-word input filter solution
body: <p>I'm building a web app with php and the codeigniter framework, and one of the requirements for the client is to implement a 'swear word' filter on from validation. Does anyone know of any prebuilt solutions written in php? Or alternatively, an exhaustive list of curse words that I can format into a php syntaxed array and check for their presence in a user's input? Thanks!</p>
