PHP:如何获取引荐来源网址?

php

我有一个页面(仅索引),客户可以在其中向我发送电子邮件,我想查看访问者来自哪个网站?

如何Referrer URL使用PHP?我尝试过, $_SERVER['HTTP_REFERER']但它一直都是空的。我怎样才能做到这一点?谢谢!

这是我$_SERVER包含的内容(“ --------被检查----”由我检查)

$_SERVER['HTTP_REFERER']如果存在,将为您提供引荐来源页面的URL。如果用户使用书签或通过手动输入URL直接访问您的网站,则http_referer将为空。同样,如果
用户 以编程方式(CURL)发布到您的页面,则他们也没有义务设置http_referer。您错过了所有_,这是一个错字吗?
