{
$message = strip_tags( $message );
if($email)

//strip email address
$email_regexp = "[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\.[A-Za-z0-9-]+)*(\.[A-Za-z]{2,3})";
$message = ereg_replace($email_regexp, 'XXX', $message);
}
if($numbers)
{
//strip all numerical values
$number_regexp = "[0-9]";
$message = ereg_replace($number_regexp, 'XXX', $message);
}
//eliminate url from message
if($url)
{
$url_regexp = "(https?://)?(www\.)?([a-zA-z0-9\.])*[a-zA-Z0-9]*\.[a-z]{2,3}";
$message = ereg_replace($url_regexp, 'XXX', $message);
}
//eliminate all the bad words
$bad_words = array("f**k", "son of a b***h");
