如何使用.htaccess创建动态子域名？

Question

  

可能重复：
  Create Subdomains on the fly with .htaccess (PHP)

我想在.htaccess中使用以下域名结构：

domain.com        REWRITES TO   Home Page (index.php)

www.domain.com    REWRITES TO   Home Page (index.php)

blog.domain.com   REWRITES TO   index.php?page=blog

*.domain.com      REWRITES TO   index.php?page=user&id=* (where * can be anything)

有没有办法创造这样的东西？

您尚未说明要重写的主机名，因此我假设使用www子域

RewriteCond %{HTTP_HOST} ^([w]{3,3}[.]{1,1}){0,1}domain.com$
RewriteRule ^$ http://www.domain.com/index.php [R,L]

RewriteCond %{HTTP_HOST} ^blog.domain.com$
RewriteRule ^.*$ http://www.domain.com/index.php?page=blog [R,L]

RewriteCond %{HTTP_HOST} !^([w]{3,3}[.]{1,1}){0,1}domain.com$
RewriteCond %{HTTP_HOST} ^([0-9a-zA-Z-]*)[.]domain.com$
RewriteRule ^.*$ http://www.domain.com/index.php?page=user&id=%1 [R,L]
