badword filter help

[KashKurcura]

Hello:

I have started a bad word filter script but I'm having some problems. The filter works fine but what I would like to happen is... if a bad word is found i would like it to add $EditText right to the beginning of the $text but only if it has found a bad word.

Any help would be great!

function WordFilter($text) {

$EditText = "This Text Has Been Edited\n";
$badwords = array("badword1","badword2","badword3");

foreach($badwords as $badword) {
	$stars = str_repeat("*", strlen($badword));
	$text = str_replace($badword, $stars, $text);
}
return $text;
}

echo WordFilter($text);

Not great but it should work -

function WordFilter($text) {

$oldtext = $text;
$EditText = "This Text Has Been Edited\n";
$badwords = array("badword1","badword2","badword3");

foreach($badwords as $badword) {
    $stars = str_repeat("*", strlen($badword));
    $text = str_replace($badword, $stars, $text);
}
if ($oldtext != $text) {
    return $EditText . "\n" . $text;
}
else {
    return $text;
}
}

echo WordFilter($text);

Hope this helps 😉

I'd advise checking out levenshtein() so you can see if people are attempting to bypass it by adding a single * or something.

levenshtein()? hmm not sure that I follow, what do you mean?
