通过http://detectmobilebrowsers.com/我使用了RewriteCond来检测移动浏览器，并将其重定向到页面的移动版本。
由于我们现在对桌面和移动设备使用统一的用户体验，我想使用相同的检测，但这样apache就会设置一个env变量来指示请求者是一个移动浏览器。通过这种方式，我可以通过检查这个var.来通过我的PHP脚本传递稍微不同的内容
有可能这样做吗

RewriteRule ^$ http://detectmobilebrowser.com/mobile [R,L]
因此，在这些条件下，Apache将isMobileEnv变量设置为true？
我们的设置是Apache 2.2.22[MPM_WORKER]+PHP-FPM 5.5.18
Magnaschi，
在构建应用程序之前，您是否考虑过使用响应式设计？因此，使用CSS和JavaScript，您可以让任何设备都可以访问您的应用程序。这样，您就不必检查用户（客户端）是在使用移动设备还是桌面设备。您不必担心将它们重定向到特定的设备。
我不确定是否有apache的移动配置，但我认为没有。
为任何可能来自谷歌的人提供答案。
诀窍是继续使用mod_rewrite，并让它在特定条件上设置env变量
因此，用这个替换RewriteRule就足够了
RewriteRule (.*) - [E=siteenv:mobile]
然后在PHP中，"siteenv"变量将可以通过访问
<?php getenv("siteenv"); ?>
完整的重写规则是：
