Probably a couple of ways you could tackle that. If you're trying to sanitize
the "$comments" variable the str_replace function may work for you. As an
example...
$newtext = str_replace($banned_words, "**censored**", $comments);
You'd still need to build the $banned_words array like you had in your example.
