我一直收到这个错误注意：未定义的变量：第226行的C：\ wamp \ www \ 5 \ adv_mail.php中的操作注意：未定义的变量：第23行的C：\ wamp \ www \ 5 \ adv_mail.php中的操作

任何帮助将不胜感激

$action肯定是未定义的。从您的代码中可以看出，您希望它是您在表单中定义的名为操作的HTML隐藏字段。这个错误只是说你试图在一些不存在的东西上运行一个switch语句。为此你应该首先初始化它。

if(isset($_POST['action']))
  $action = $_POST['action'];  // This is missing
else
  die("No action defined");

switch ($action)
{
....
}
