Code

function page_example_arguments($first, $second) {

  // Make sure you don't trust the arguments to be safe! Always check for exploits.
  if (!is_numeric($first) || !is_numeric($second)) {

    // We will just show a standard "access denied" page in this case.
    drupal_access_denied();
    return;

    // We actually don't get here.
  }
  $list[] = t("First number was @number.", array(
    '@number' => $first,
  ));
  $list[] = t("Second number was @number.", array(
    '@number' => $second,
  ));
  $list[] = t('The total was @number.', array(
    '@number' => $first + $second,
  ));
  return theme('item_list', $list);
