Hi all,

Just wanting to pick your collective brains on this one:

How do you go about implementing a swear / bad-word filter in PHP?

Reasons for needing one aside, I'm just wondering if you favour a
regexp, a substr_count, or what? Do you like to *** out the bad words,
or just error back to the user? (I guess that is application
specific).

There are always ways to circumvent them, but I'm still curious to
know how you prefer to handle it.

Cheers,

Rich

Why not just use str_replace() with a list of words?

$bad_words = array('foo', 'bar', 'baz');
$dirty_sting = 'Go foo yourself you baring baz!';

$clean_string = str_replace($bad_words, '****', $dirty_string);
