Php 显示目录内容的子域

我正在开发一个有访问规则的网站。这是url结构：

example.com
example.com/index.php/login
example.com/index.php/foo
demos.example.com

对于上面的最后一个url（demos.example），我想显示

example.com/index.php/demos

的内容，因此，我创建了一个.htaccess文件，如下所示：

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(www\.)?demos.example.com
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/demos [L]

RewriteCond %{HTTP_HOST} ^(www\.)?demos\.example\.com 
RewriteRule ^(.*)$ index.php/demos/$1 [L]

当我浏览

demos.example.com

时，会显示索引页（example.com），因为没有发生任何事情。我希望我的解释清楚

• 我已经读过了，但是这个解决方案做了一个“浏览器重定向”，这不是我的想法
• 使用不会产生任何结果：显示索引而不是index.php/demos

更新 如果我按如下方式使用.htaccess：

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(www\.)?demos.example.com
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/demos [L]

RewriteCond %{HTTP_HOST} ^(www\.)?demos\.example\.com 
RewriteRule ^(.*)$ index.php/demos/$1 [L]

…这会使浏览器显示

500内部服务器错误

。查看日志时，它会打印以下消息：

试试这个：

RewriteCond %{HTTP_HOST} ^(www\.)?demos\.example\.com [NC]
RewriteRule ^(.*)$ http://example.com/index.php/demos/$1 [L]

这使得浏览器重定向为“点”，正如我在postAh中所述，所以你希望它保持URL不变，但显示来自另一个域的内容？我认为这实际上是不可能的。。它是？我的意思是，我确信你应该能够通过在你的DNS记录中设置一个虚拟服务器来做到这一点。但是使用.htaccess。。我怀疑。我认为这是可能的。它不是来自另一个域，只是来自同一个域的另一个“段”。对，一个子域。好的，我很想自己看看解决方案。好吧，不可能显示来自另一个域的内容，但可能来自同一个域（使用文件名而不是完整的url）。然而，为了让它工作起来，我做了一些修改，但在应用程序方面，与.htaccess无关
