80giga, this works for me, try to replace:

{

{
//-- test for encoded keyword
if (preg_match($match, $token, $kmatch)) {
//-- ensure that the substitute replaces value with the case-sensitive match
if ($match_replace == 1) {
$substitute = preg_replace('/\b' . htmlentities($keyword) . '\b/', $kmatch[0], $substitute);
}
//-- replace keyword with the substitute
$token = preg_replace($match, $substitute, $token);
$must_tokenize = TRUE; //-- re-tokenize next time around
//-- test for non-encoded keyword
}
elseif (preg_match($match_noencode, $token, $kmatch)) {
//-- ensure that the substitute replaces value with the case-sensitive match
if ($match_replace == 1) {
$substitute = preg_replace('/\b' . $keyword . '\b/', $kmatch[0], $substitute);

}
} else //-- this token is markup
{

$anchor_level++;
}

$anchor_level--;
}

$tag_level++;
}

}
}
$filtered .= $token; //-- this token has now been filtered

with
$isfound[$match] = 0;
