[dz-id]

cookie helper not working,

helper("cookie");
$app = config("App");

set_cookie(
 "token",
 "test",
 time() + 3600,
 $app->cookieDomain, // "localhost:8080"
 $app->cookiePath, // "/"
 $app->cookiePrefix, // ""
 $app->cookieHTTPOnly, // false
 true
);

dd(get_cookie("token")); // null

I tried to refresh the browser, but the result was the same // null

This is a common pitfall with cookies. Quoting PHP.net:

Cookies will not become visible until the next loading of a page that the cookie should be visible for.

CI4's set_cookie sets a new cookie in the Response object but it sits there until the headers are sent. get_cookie uses the Request object to retrieve the cookie in the $_COOKIE array. In your example, since you are setting and getting the same cookie on the same page, then cookies are not sent to the browser and therefore the $_COOKIE is not populated with the cookies in the Response. That's why you are getting null (i.e., cookie not in $_COOKIE).

To achieve your desired result, create two pages: (1) setting the cookie; (2) getting the cookie. In your cookie-setting page, you will redirect with cookies to the cookie-getting page, something like redirect('/my-cookie-getter')->withCookies();. Then, there the dd should show the cookies.

Side note: The arguments order supplied in set_cookie in your example is wrong.
