推荐答案

看过这段代码后，由于所有安全漏洞，我绝不会使用你的网站。 />


但是，如果没有发送电子邮件，那么您的邮件服务器设置不正确，而不是这段代码有多糟糕..



现在，密码被加密存储，并且无法向他人发送密码，通常，您只能发送使用GUID与用户关联的重置链接，或者他们下次登录时需要更改的临时密码。

Having seen this code, I would never use your website, due to all the security holes.

But, if the email is not sent, then your mail server is not set up correctly, not a big leap from how bad this code is.

Nowadays, passwords get stored encrypted, and it is impossible to send someone their password, all you can do, generally, is send a reset link that uses a GUID to associate with a user, or a temp password they need to change the next time they log in.
