Recently, chrome has been upgraded to version 80. SameSite has set Lax by default, causing some users to be unable to log in normally.

I see that php7.3 already supports configuration, but the parameters in php.ini do not support None and setcookie listening It says it can be set, but I haven't found any documentation on it, and the latest manual doesn't introduce the same parameters as before. Is there any way to solve it? (My colleague can ask him to disable this in Chrome, but he can't let everyone do this. Yeah), I also thought about configuring it in nginx, but I feel that this solution is not the solution, please give me some advice
