Question

我想在用户请求a.domain.com/index.php或b.domain.com/index.php时将流量重定向到特定文件，它会重定向到domain.com/index.php

You can use this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.domain\.com$ [NC]
RewriteRule ^(index\.php)$ http://domain.com/$1 [L,NC,R]
