如何唯一地识别计算机?

问题描述：

有什么办法可以抢"一些个性化的ID，INFO，NAME，NUMBER，DATA等?

Is there any way to 'grab' some personalized ID, INFO, NAME, NUMBER, DATA, etc.?

是否只是要区分和识别同一IP上的两台或更多PC:是否像$_SESSION之外的用户计算机名?

Anything just to differentiate and recognize two or more PC on the same IP: something like the Computer name of the user besides $_SESSION?

这些工作都没有:

$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);
php_uname('n');
php_uname();

基本上，您可以使用 Evercookie 的概念来识别客户端.话虽这么说，为什么不只使用登录系统呢?

Basically, you can use the concepts of Evercookie to identifiy a client. That being said, why not just use a login system?
