Apache/PHP:通过PHP检索ServerName设置的任何方法 [英] Apache/PHP: Any way to retrieve the ServerName setting via PHP

问题描述

我有一个如下所示的Apache虚拟主机:

I have an Apache virtual host that looks like this:

<VirtualHost *:80>
    ServerName host1.example.com
    ServerAlias host2.example.com
    DocumentRoot /srv/web/host1.example.com/pub
</VirtualHost>

我有以下文件:

/srv/web/host1.example.com/pub/test.php

我正在请求以下URL(请注意，我使用的是ServerAlias，而不是ServerName:

I am requesting the following URL (notice that I am using the ServerAlias, not the ServerName:

http://host2.example.com/test.php

我想让test.php以某种方式输出ServerName变量(host1.example.com).有什么办法吗?

I'd like to have test.php output the ServerName variable somehow (host1.example.com). Is there any way to do that?

推荐答案

显然，当您通过别名访问VirtualHost时，没有任何原始痕迹 任何$_SERVER变量中的SERVER_NAME.

Apparently, when you access a VirtualHost through the alias, there is no trace of the original SERVER_NAME in any of the $_SERVER variables.

唯一想到的是设置环境变量:

The only idea that comes to mind is setting an environment variable:

SetEnv MY_HOST host1.example.com

这应将$_SERVER["MY_HOST"]的值设置为正确的主机名.不过，不能保证，我从未在实践中尝试过此方法.

this should set the value of $_SERVER["MY_HOST"] to the correct host name. No guarantees though, I have never tried this in practice.
