$_POST,$_GET..)需要检测变量是否已经设置。使用$uname = isset($_SESSION['MM_username']) ? $_SESSION['MM_username'] : '';而不是$uname = $_SESSION['MM_username'];当然实际项目中往往是屏蔽notice信息的，使用error_reporting(E_ALL ^ E_NOTICE);或者在php.ini里作相应修改即可。
session_start();需要在页面的最开始使用，同样你在b.php中也使用这个函数，然后再echo试试，a.php报什么错误？
问题2：在使用任何可疑变量之前，使用isset（）、empty（）条件效果良好。
提示你程序编码错误：F:\phpnow\htdocs\inc\menus.php on line 45 如果确认程序无错，就重新安装phpnow吧！！全部默认，不要自定义操作，再测试！！
使用SESSION必须在页面顶端加上 <?php session_start();?>
