The following code does the job:

function badWordFilter($data)
{
    $bad = preg_split('/\r\n|[\r\n]/', $_POST['bad']);
    $originals = array_map('strtolower', array_filter($bad));;

    $words = array_map('trim', explode(' ', $data));
    $filtered = array_filter($words, function($v) use ($originals) { 
        return !in_array(strtolower($v), $originals); 
    });

    return implode(' ', $filtered);
}

It splits the string into words, filters out bad words and builds new filtered string.

Try the following code:

function wordFilter($text)
{
    $filter_terms = array('\bass(es|holes?)?\b', '\bshit(e|ted|ting|ty|head)\b');
    $filtered_text = $text;
    foreach($filter_terms as $word)
    {
    $match_count = preg_match_all('/' . $word . '/i', $text, $matches);
    for($i = 0; $i < $match_count; $i++)
        {
        $bwstr = trim($matches[0][$i]);
        $filtered_text = preg_replace('/\b' . $bwstr . '\b/', str_repeat("*", strlen($bwstr)), $filtered_text);
        }
    }
    return $filtered_text;
}

You can easily add words into the $filter_terms array; note that the beginning / and trailing /i are automatically included in the loop, eliminating the need to type them every time. You can also add "greedy" matches; simply remove the \b from both ends of the word, and the filter will catch anything that contains that word within it. A good idea would be to load all of the terms into the array from an external file.
