获取最后访问的页面 [英] Get last page visited

问题描述

我需要知道访问我网站的人是否来自另一个特定网站. 示例:

I need to know if a person that comes to my website went from an another specific website. Example:

• 用户A访问www.youtube.com/myvideo并单击指向我的网站的链接.
• 用户B访问google，搜索我的网站，然后单击链接.

我的页面上的结果消息:

Results Message on my page:

• 用户A:Welcome! You already know how it works, register now!
• 用户B:Welcome! Please watch our video first at www.youtube.com/myvideo

• User A: Welcome! You already know how it works, register now!
• User B: Welcome! Please watch our video first at www.youtube.com/myvideo

我的问题是:

1. 在进入我的页面之前是否可以知道用户访问的最后一个URL?
   我已经使用PHP尝试了$_SERVER['HTTP_REFERER']，但是它不能正常工作，并且我读到它不适用于所有浏览器.
2. 是否存在任何语言或PHP脚本来获取此网址，并且可以在所有浏览器上正常工作?

1. Is it possible to know the last url the user visited before entering my page?
   I already tried $_SERVER['HTTP_REFERER'] with PHP, but it's not working correctly and I read that does not work on all browsers.
2. Is there any language or php script to get this url, working on all browser correctly?

推荐答案

HTTP引用标头是唯一的方法.这是通过$_SERVER['HTTP_REFERER']在PHP中提供给您的数据.

The HTTP referer header is the only way. This is the data that is given to you in PHP via $_SERVER['HTTP_REFERER'].

请注意，此标头在大多数情况下均可使用.另外请注意，它很容易被欺骗.

Note that this header will work in most cases. Also note that it can be easily spoofed.
