单这句就有错误：
1.结尾的；没加。
2.正确的应该是
echo "<script language='javascript'>window.location.href='cookie_test.php'</script>";
或者echo "<script type='text/javascript'>window.location.href='cookie_test.php'</script>";
$_COOKIE是接收客户端发过来的cookie信息的，虽然你setcookie('id',$_POST['user'])，但这个cookie信息刚刚有服务器发往客户端的，而客户端还没有给服务器发送任何信息，所有$_COOKIE的值还没有被定义你尝试再刷新一次，这个时候就是登陆状态了，但实际的情况是你接收到的cookie是上一次的，而不是本次的
