Answer 1

正是这一部分作为邮件返回布尔发送消息。第一paramters是解决（见链接）

if(@mail($email, $subject, $msg, $headers)) 

http://php.net/manual/en/function.mail.php

在本例中的电子邮件将进入用户输入如所见到的$email填充了贴值

$email=$_POST['email']; 

地址

但你可以硬编码到任何你想要的。

if(@mail('[email protected]', $subject, $msg, $headers)) 

Answer 2

本教程似乎有一些错误（至少乍一看）。

它使用$cc但是这个变量没有在任何地方定义。

它将消息发送到$email但$email = $_POST['email']（第42行），因此它将该电子邮件发送到以（？）形式提供的电子邮件地址。您想要修复第62行：

if(@mail('[email protected]', $subject, $msg, $headers)) 

它也不会消毒输入，因此您可以将标头注入电子邮件。更多解释here。

最后，如果CC的功能被正确执行（即$cc定义），你需要发送电子邮件的副本发送者（CC），从而揭示你的e-mail地址（如果你想不好避免垃圾邮件）。您应该发送一封单独​​的电子邮件给发件人。
