How to make the choice of front page depending on domain name in Joomla website

Question

I have a website, let's call it mydomain.com, hosted by host provide Siteground.

I have created a subdomain, let's call it sub.mydomain.com, and I have set the root folder of the subdomain the same as the main domain. As a result, the subdomain shows the same contents, in every of its pages, as the main domain.

Now I would like to have a different home page for the main domain and for the subdomain.

So I wish write a php code (maybe in the index.php of the root folder), so that, depending on the value of the current domain name ("mydomain.com" or "sub.mydomain.com"), the default home menu is set accordingly.

The website is based on Joomla 2.5
