filter language for text field input

[john_6767]

ok, i have people entering comments into my page in a basic forum style.. how do i stop them from ebtering swear words or replace 'rude' words with suitable ones?

i figure there is a common script out there for this?

[code]
<?php
$original_text = "This is a bword1 place! I hate this bword2";

$bwords = array('bword1','bword2','bword3');
$gwords = array('gword1','gword2','gword3');

str_replace($bwords, $gwords, $original_text);
?>[/code]
