$ _SERVER ['REMOTE_ADDR']的问题 [英] problem with $_SERVER['REMOTE_ADDR']

问题描述

我使用$ _SERVER ['REMOTE_ADDR']并返回客户端IP地址（用户正在查看当前页面的IP地址），但是现在（和相同的代码）它返回主机IP地址（我检查了ip地址） ip位置）。问题是主机还是什么？
谢谢你。

i used $_SERVER['REMOTE_ADDR'] and it returns client ip address (IP address from which the user is viewing the current page) but at now (and same code) it returns host ip address (i checked ip address with ip location). problem is with host or what? thank u.

推荐答案

你应该查询 HTTP_X_FORWARDED_FOR 首先，如果未分配，请使用 REMOTE_ADDR 。

You should query for HTTP_X_FORWARDED_FOR first and if it isn't assigned use REMOTE_ADDR.
