Rewrite URL to Generate Subdomains form Subdirectory

Hi: this is a small project that can be done in a few hours. This is what we need... We have an addon domain that will be used as an extension of a subdomain (just like wordpress does). We have this structure... For Ex: [login to view URL] That means on the server via FTP we have... For Ex.: public_html/my-dir/my-subdir1/[login to view URL] What we need is that EVERY subdir (for example my-subdir1) inside the folder... my-dir, work as a sub domain, which must be AUTOMATICALLY generated once every new folder is created (note that is not the first subdir after /public_html/, but the second). Note that is not necessary that the sub domains really exists on the cpanel, they must be created AUTOMATICALLY on each new folder. Is just an URL re written (Not Redirect) to give the appearance of sub domains. Wildcard subdomains is active. This is how will look... [login to view URL] IMPORTANT: it is not just for the [login to view URL] file, but for all the site structure, for example... If I go to... [login to view URL] I MUST see... [login to view URL] Hundreds of sites in the world do it, for example wordpress, blogspot, etc. When I create a blog in wordpress my address is... [login to view URL] That doesn’t mean that wordpress administrator has to generate each sub domain from the Cpanel, because this is done AUTOMATICALLY.
