How can I create a personal subdomain programmatically using php

Question

if I like to create a user for each domain, how technically do I do it?
for example, if user XXX is registered on my site, and I have connected him to the domain http://xxx.mydomain.com/ or http://www.mydomain.com/xxx/
What is the procedure for creating it?

Answer 1

You need to set up a wildcard DNS record to catch all the subdomains and send them to you on the web server.

Then you need to configure Apache to catch all named virtual hosts and send it to a directory.

In the directory, you must install htaccess to send all requests to a single script that will read the subdomain from the server variables and process it accordingly.

Answer 2

If you want mydomain.com/xxx, then this is just a folder. Some hosts will also take mydomain.com/xxx and automatically make xxx.mydomain.com a link to it without any configuration on your part. You might want to verify that this is not the case.

Answer 3

How do you create a subdomain manually?

Good. Now automate it.
