我有一个页面(只有索引),客户可以向我发送电子邮件,我想看看访问者来自哪个网站?

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

以下是我的$_SERVER包含的内容(“---- CENSORED ----”由我审核)

4 个答案:

答案 0 :(得分:120)

如果存在,

$_SERVER['HTTP_REFERER']会为您提供引荐网页的网址。如果用户使用书签或通过手动键入URL直接访问您的站点,http_referer将为空。此外,如果用户以编程方式(CURL)发布到您的页面,那么他们也没有义务设置http_referer。你错过了所有_,这是一个错字吗?

下划线。不是空间。

$_SERVER['HTTP_REFERER']

答案 2 :(得分:2)

如果$_SERVER['HTTP_REFERER']变量似乎不起作用,那么您可以使用Google AnalyticsAddThis Analytics

答案 3 :(得分:0)

$_SERVER['HTTP_REFERER'];

但是,如果通过直接在浏览器中点击URL运行文件(包含上面的代码),则会出现以下错误。

注意:未定义索引:HTTP_REFERER
