    function filter ($type, $input, $min = null, $max = null)
    {
        $type = strtolower($type);
        if ($type == "string")
        {
         if($min == null && $max == null){
         {
             return (filter_var($input, FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH)) ? $input:false;
         else
         {
             if (strlen($input) < $min || (strlen($input) > $max )
            {
                 return false;
            }
            else
            {
                return $input;
            }
         }
        }
        elseif ($type == "int")
        {
         return (filter_var($input, FILTER_SANITIZE_NUMBER_INT)) ? $input:false;
        }
        elseif ($type == "url")
        {
         return (filter_var($input, FILTER_SANITIZE_URL)) ? $input:false;
        }
        elseif ($type == "ip")
        {
         if (filter_var($input, FILTER_VALIDATE_IP)) ? $input:false;
        }
        elseif ($type == "email")
        {
         if (filter_var($input, FILTER_SANITIZE_EMAIL)) ? $input:false;
        }
    }
?>
