How to make id_guest integer for each user in YII2 to write in cookie?

Question

Yii

It is necessary for each user to give his unique guest id when entering the site, tell me how to do it correctly!

Answer 1

Do you have a rubber database? Imagine that a shkolota comes to your site to automatically search for vulnerabilities. They do not save cookies, each request for you will be supposedly a new guest. Millions of new id_guests per day - do you need it?
