Can anyone recommend a php or javascript bad words filter? There's so many out there, I am really not sure which one to use. I want one for textarea in a guestbook.

Thanks,

Here's some code I wrote awhile back. Be sure to sort the array of bad words with the largest at the top.

PHP Code:

<?php
$word_list = array("/(reallybad)/ei",
                   "/(bad)/ei");
$string = "This sentence doesn't contain bad or reallybad words. Bad words shouldn't really be used by people unless they're reallybad people.";
echo preg_replace($word_list,"preg_replace('/[a-z]/i','*','\\1')",$string);
?>

I think that should be:

PHP Code:

<?php
$word_list = array("/(reallybad)/ei",
                   "/(bad)/ei");
$string = "This sentence doesn't contain bad or reallybad words. Bad words shouldn't really be used by people unless they're reallybad people.";
echo preg_replace($word_list,preg_replace('/[a-z]/i','*','\\1'),$string);
?>

or

PHP Code:

<?php
$word_list = array("/(reallybad)/ei",
                   "/(bad)/ei");
$string = "This sentence doesn't contain bad or reallybad words. Bad words shouldn't really be used by people unless they're reallybad people.";
echo preg_replace($word_list,"[Thats a bad word]",$string);
?>

I guess context would have helped. The code I replaced replaces each letter of the banned word with an asterisks. the preg_replace does actually have to be quoted for it to work correctly.
