什么是pgv_si和pgv_pvi

Question

I'm using PHPV7, I found there is pgv_si and pgv_pvi. I can't find them from PHP.net official website. Anyone knows what is that?

The code is below:

var_dump('cookie', $_COOKIE);

I understand it is generated by cookie, but I don't know what is that for...

Answer 1

Those are just some variables in cookies, set by server. Please read some documentation on cookies, that does not have any connection to PHP itself.
