@NogDogOct 20.2006 — #Here's what I've come up with after thinking about it a bit:
updated bad word filter- explode it?
I am using a simple but effective “bad word” filter on my site –
Bad_word Filter code:
[code]
$bad_words = explode(‘|’, ‘badword1|badword2|badword3|etc|etc’);
foreach ($bad_words as $naughty)
{
$comments = eregi_replace($naughty, “#!@%*#”, $comments);
}
but as always when you solve one little problem you come up with another, those pesky kids and their rude #!@%*# words.
As I’ve added words to the filter they are replaced with other words where one or more characters have been replace with symbols or digits. i.e. in the word ‘*****’, [sorry for any offence to Meredith Brooks fans, or anybody else for that matter] this is easily be filtered on its own using a list, but the same word spelt ‘8itch’, B1tch, Bi+ch etc. could be equally offensive.
Any ideas? (Short of trying to work out every connotation of every word)
