Why waste your time? People will find a way around the filters anyway, if they really want to use the words you're censoring. Just a point to be made. Anyway, here's what I would do: function filterWords($str){ $badwords = array("shit", "fuck", "ass", "bitch"); for($i=0; $i<count($badwords); $i++){ $str = $eregi_replace("$badwords[$i]", "*****", $str); } return $str; } $str = filterWords("Ass monkey"); print $str; // Prints "***** monkey" If you want to get really fancy, you can replace the "*****" with some function calculating just how many asterisks you need to censor out the current word for its length.
