Thisis what I was using for my old admin system now gone
if ($action == "login") {
if ($username == "admin" || $password == "admin") {
setcookie("admin", "loggedin", "+3600");
header('Location: admin.php');
}
else {
$error = "wrong password";
}
}
elseif ($action == "logout") {
setcookie("admin", "loggedout", "-3600");
header('Location: http://216.118.121.28/pw/');
}
echo $error
