我正在努力弄清楚如何根据我的场景使用 SetEnvIf 让环境变量工作，并且想知道是否有人可以告诉我如何去做，或者举个例子。

我的结果是我需要根据环境变量触发以下重定向，我还有其他情况也需要使用此逻辑。

我有以下内容，所以重定向只发生在生产中

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{ENV:environment} production
    RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</IfModule>

我希望我可以设置以下内容，但无法弄清楚。

SetEnvIf environment ^(.*)$ environment=production #set it to production, if it is not already set?
SetEnvIf Host ^staging. environment=staging
SetEnvIf Host .dev$ environment=wamp

理想情况下，我的伪代码是

SetEnvIf environment is not set, set to production
SetEnvElse host starts with staging, set to staging
SetEnvElse host ends with dev, set to wamp

然后在我的PHP中我有

<?php

if( getenv('environment') ){
    exit(getenv('environment'));
}
else {
    exit("environment not found");
}

我的输出肯定是

environment not found

我正在访问owen.jekyll-test.dev

谁能指出我做错了什么的方向？

几个小时后，我终于有了一个可行的解决方案，它允许基于环境的动态 .htaccess

对于任何对类似设置感兴趣的人，这里是我们的配置，它自动处理 SSL、WWW 重定向、Apache Auth 和 Is_Admin 标志。

SetEnvIf Remote_Addr ^43\.432\.136\.23 is_admin=1 # Virgin Media
SetEnvIf Remote_Addr ^81\.43\.184\.70 is_admin=1   # BT
