推荐答案

您在注册页面末尾看到的图片名为CAPTCHA [ ^ ]。它是防止用机器填写表格。事实上，您可能会编写一些解码图片中文本的应用程序，但是由于图片是专门为了不被软件解释而创建的，因此可能会对您不利......

The picture you see at the end of the registration page called CAPTCHA[^]. It is there to prevent to fill the form by machine. In fact it is possible that you write some application that decodes the text in the picture, but the chances are against you as the picture was created specially for NOT to been interpreted by software...

Kornfeld给出了验证码的含义。

如果你想在php中实现这个，你可以探索 Securimage [ ^ ]

还有其他选择，只需询问Google。

Kornfeld has given the meaning of captcha.
If you want to implement this in php, you may explore Securimage[^]
There are other alternatives, just ask Google.
