.htaccess中的动态环境变量

Question

我很难弄清楚如何根据我的场景使用SetEnvIf让环境变量发挥作用，我想知道是否有人能告诉我如何做到这一点，或者举个例子。

我的结果是，我需要以下重定向到基于环境变量的fire，我还有其他情况也需要使用这种逻辑。

我有下面的，所以重定向只发生在生产上

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

我希望我能设置以下内容，但无法实现。

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psudo代码应该是

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，我得到了

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

我的输出肯定是

environment not found

有人能告诉我我做错了什么吗？

几个小时后，我终于找到了一个可行的解决方案，它允许基于动态.htaccess的脱离环境

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