So been doing the tutorial for a while now
and i noticed something small in the delete cookie tutorial, the cookie never gets "deleted" I've checked it with the debugger and if you solely use
setcookie("user", "", time() - 3600);
Nothing changes and the cookie still exists $_cookie still hold the the value (i've refreshed several times and even closed my browser)
But adding the line
unset($_COOKIE['user']);
Does remove the cookie properly
