The cookie in PHP takes effect immediately and does not need to refresh the page again

PHP's Cookie is the first time that a cookie is created and the page is refreshed again to use this value.

Setcookie ($var, $value, $time, $path, $domain, $s); Suppose the cookie name is called $var, and the value is $valuecookie[$var] = $value;

First create a cookie with the Setcookie function , and then assign the cookie.

This allows you to get the value of the cookie directly without having to refresh it again.

That is, the cookie was assigned two times.
