How do you set a php cookie with multiple values?

Question

I want to create a php cookie that stores the username and the userid. Or is it better to just use one to get the other?

Answer 1

I know it's an old thread, but this might save a future me some headache. The best way I believe would be to serialize/unserialize the data.

setcookie('BlueMonster', serialize($cookiedata);
$arCookie = unserialize($_COOKIE['BlueMonster']);

(hijacked from https://www.brainbell.com/tutorials/php/Saving_Multiple_Data_In_One_Cookie.htm since it was far more complete than I would have thrown together in 5 mins)

 $value) {
      $cookiedata[$name] = $value;
    }
    setcookie('cookiedata',
      serialize($cookiedata),
      time() + 30*24*60*60);
  }
  function getAllCookieData() {
    if (isset($_COOKIE['cookiedata'])) {
      $formdata = $_COOKIE['cookiedata'];
      if ($formdata != '') {
        return unserialize($formdata);
      } else {
        return array();
      }
    } else {
      return null;
    }
  }
  function getCookieData($name) {
    $cookiedata = getAllCookieData();
    if ($cookiedata != null &&
      isset($cookiedata[$name])) {
        return $cookiedata[$name];
      }
    }
    return '';
  }
?>
