Use .htaccess to rewrite any subdomain to the corresponding subdir without revealing the subdir

Question

I have a little problem with my .htaccess. For example, if I go to test.example.com, it's in folder /sub/test. But it shows test.example.com/sub/test. How can I hide the path after .com? Or is there any way to do it with Apache, like all folders in sub folder are subdomains?

I don't know how to do it.

I'm using this:

RewriteCond %{HTTP_HOST} ^((?!www\.).+?)\.example\.com$ [NC]
RewriteRule ^((?!sub/).*)$ /sub/%1/$1 [L]

EDIT: I want to make every created folder in sub folder as a subdomain automatically. Like user create folder and it's subdomain.

Remove your rules and just have something like:

<VirtualHost IP>
    ServerName test.example.com
    DocumentRoot /whatever/sub/test

(replace whatever by the correct path, and IP by the relevant IP/port based on how your virtualhosts are configured)

For dynamic virtual host have a look at module mod_vhost_alias http://httpd.apache.org/docs/2.4/mod/mod_vhost_alias.html), quoting from documentation:

For simple name-based virtual hosts you might use the 
following directives in your server configuration file:

UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/vhosts/%0"

A request for http://www.example.com/directory/file.html will be 
satisfied by the file
/usr/local/apache/vhosts/www.example.com/directory/file.html.

Otherwise, for your rewrite rules, it may work just by adding [P] as flag, but as a general rule I always recommend to find simpler ways to do things and use rewriting only if things can not be done otherwise (due to the complexity it adds).
