How to make sure that the data remains when the page is refreshed?

Question

PHP

I have authorization on the site through VK. after authorization, the user data is displayed, but nothing is displayed when the page is refreshed, since the url vklogin.php?code=35dc63cc6e9731f116 is not replaced. if you go back to the login link, then everything is displayed normally, since the code becomes different. how to make the link not have this code, but just a link and when the page is refreshed, the data remains?

Sea options.

Answer 2

cookie

Answer 3
