sendCodeTest.php
<?php
header("Content-Type: text/html; charset=utf-8"); //引入发送邮件类
require("smtp.php");
//使用163邮箱服务器

//163邮箱服务器端口

//你的163服务器邮箱账号

//邮件内容
$mailbody = "PHP+MySQL";

//这里面的一个true是表示使用身份验证,否则不使用身份验证.

//发送邮件

注意：
- 该代码得设置邮箱得授权码，163邮箱设置得地方：设置-客户端授权密码-重新授权码
- 使用这个发邮件，邮件可能会进入垃圾箱或者被拦截
方式2:使用socket协议发送邮件
