PHP,Nginx获取访问网站来源的方法

Jun 06, 2016 pm 08:14 PM
nginx php

想获取访问网站的来源网址,访问此网站经过了微博的短链接,还有nginx跳转,使用HTTP_REFERER是能获取一部分访问来源,但有很多的访问来源无法准确获取到,请问有什么好办法能准确获取到访问的来源?

<code>$url = $_SERVER["HTTP_REFERER"]; //获取完整的来路URL

 

$str = str_replace("http://","",$url); //去掉http://

$strdomain = explode("/",$str); // 以“/”分开成数组

$domain = $strdomain[0]; //取第一个“/”以前的字符

 

用上面的方法才准确无误,如果你用PHP自带的函数就不对如:

$_SERVER['SERVER_NAME'] 这个函数它获取的是服务器域名</code>
