信息列表，我们可以从访客使用PHP，Javascript

Question

如您所知，Google和Facebook会使用不同的方法获取有关其访问者的大量信息（用户自己提供的信息除外），以便他们可以为网站提供服务。根据用户信息投放广告。所以我想要一个完整的信息列表，我们可以使用PHP，JavaScript等从我们的网站访问者那里获得，如果还有其他方法。

以下是我所知道的一些事情。如果你知道其他任何事情，那么请用它的方法回答。谢谢。

PHP列表：

$_SERVER["REMOTE_ADDR"];
$_SERVER["HTTP_X_FORWARDED_FOR"];
$_SERVER["REMOTE_ADDR"]; 
$_SERVER["HTTP_X_FORWARDED_FOR"]; 
$_SERVER["HTTP_FORWARDED"]; 
$_SERVER["HTTP_CLIENT_IP"]; 
$_SERVER["HTTP_VIA"];
$_SERVER["HTTP_XROXY_CONNECTION"];
$_SERVER["HTTP_PROXY_CONNECTION"];
$_SERVER["HTTP_USERAGENT_VIA"];
$_SERVER["HTTP_USER_AGENT"];
$_SERVER["HTTP_ACCEPT_LANGUAGE"];
$_SERVER["REMOTE_HOST"];
$_SERVER["HTTP_CONNECTION"];
$_SERVER["SERVER_PROTOCOL"];
$_SERVER["HTTP_REFERER"];
$_SERVER["HTTP_ACCEPT"];
$_SERVER["HTTP_CACHE_CONTROL"];
$_SERVER["HTTP_CACHE_INFO"];
$_SERVER["HTTP_X_CLUSTER_CLIENT_IP"];

您正在寻找的信息类型通常称为浏览器指纹识别。您可以在此处收集有关访问者的特定信息，以便在不使用Cookie的情况下对您的网站访问者进行编目和跟踪。

以下是基于fingerprintjs2项目（https://github.com/Valve/fingerprintjs2）的Javascript跟踪信息列表...
