验证错误不能登陆，需重新输验证码，或在发送新的验证码到邮箱。为了实现此功能，我用到了如何向邮箱发送邮件，以及获取登陆ip的知识

这段时间修改了一下我们系统的登陆功能，为了更加安全，增加了发送邮件验证功能。当用户登陆的时候判断登陆ip是否是之前登陆过的，如果不是的话，需要向邮箱里发送验证码，然后把收到的验证码输入再登陆，如果验证码正确并且时间没有超过规定时间，可以登陆，并且记下此次登陆的ip和时间，以后再以此ip登的话，就不用验证了。如果时间超过了，，验证码失效，需重新发送。验证错误不能登陆，需重新输验证码，或在发送新的验证码到邮箱。为了实现此功能，我用到了如何向邮箱发送邮件，以及获取登陆ip的知识。下面整理一下，以便以后自己查看。

发送邮件：

首先需要下载phpmail的压缩包，然后解压，把解压后的文件复制到项目中。在项目中引入文件。

复制代码 代码如下:


require("phpmailer/class.phpmailer.php"); //文件的路径具体看自己的项目中的路径是怎么样的
