Email接收验证码，以实现登录/注册/修改密码
要求
1）实现Email形式的注册功能和相应的登录功能；
2）实现忘记密码时的密码找回功能；
3）存在数据库中的密码不能以明文形式存放，即建议在浏览器端发送请求前，调用js代码对用户的密码做md5加密
分析
第3）点较简单，重点学习一波email接收验证码。
网上粗略了解了一下，PHP自带mail()函数可实现邮件的收发，但在php5.3版本后需开启本地email服务器才能使用。
所以搭建了hmailserver服务，具体参考：
mysql+hmailServer+roundcubemail整合开发（一）

先判断账号/密码是否为空/合法
没输入验证码就注册
注册用户已存在
否则
登录邮箱接收验证码
验证码有效时间1分钟
成功注册，3s后自动跳转login.php
