You can make virtual subdomains and configure your server to treat each subdomain as parameter for the single script.

For example would map to and to Then your script may analyze user parameter and grab different data from database.

There are lot of tutorials on this topic around, like this one

In fact there is no point in configuring a server to treat each subdomain as a parameter, simply because the requested host is always available to PHP.

A custom template could be a problem though. There needs to be a storage for them.

May be a directory with subdirectories for each user. For this, a simple rewrite rule could be of some use.

Well, requested host is a parameter itself :smiley:

If these templates differ only with CSS (most obvious solution for the blog platform IMHO), then it’s quite easy to store custom styles in database. Even simplier if there is predefined set of templates that users can choose from. In this case template_id is the only thing to store.
