Question

I’m trying to access a cookie I just set in an other page on the same domain, but it doesn’t work. When I’m doing echo $_COOKIE, the array is empty on the new page, but contains the cookie on the creation page.

Here is the code in /PROC/LOGIN.PROC.PHP

//Set the cookie for 1 year.
setcookie("username", $username, time()+365*24*60*60);
setcookie("password", $password, time()+365*24*60*60); 

Here’s the code in /INC/HEADER.INC.PHP

if (isset($_COOKIE['username']) && isset($_COOKIE['password'])) {
include("pages/user.header.pages.php");

But when I’m trying to isset the cookie or only display the array in header.inc.php, the array is empty.

You need to set the path value of the cookie to the root of your domain, as per the docs:

setcookie("username", $username, time()+365*24*60*60, '/');

Otherwise, it will be set to the current working directory, which is /PROC/ for your example. So, only scripts in /PROC/ would be able to use that cookie.
