The cookie

Answer 1

This is syntax for setting a cookie

setcookie(name, value, expire, path, domain);

When you create a cookie, using the function setcookie, you must specify three arguments. These arguments are setcookie(name, value, expiration):

1. name: The name of your cookie. You will use this name to later retrieve your cookie, so don't forget it!
2. value: The value that is stored in your cookie. Common values are username(string) and last visit(date).
3. expiration: The date when the cookie will expire and be deleted. If you do not set this expiration date, then it will be treated as a session cookie and be removed when the browser is restarted.

Note:- This will rewrite your cookie not update.
