How to block another domain to access and get result from my website?

Question

Another domain is showing duplicate content of my website (all pages) When I entered this domain I see my site content.

If I change something on my site, I see it immediately on the another domain.

I think he's using some function fopen or curl or something else to show my content immediately from my website

How do I block it?

*my server: cpanel, php5

You can use their IP address to serve them a 404 page. Or if you really want to be clever. For just their IP address serve wrong or embarrassing information that looks similar but is not the good content.

if($_SERVER['REMOTE_ADDR'] == "12.1.3.5"){ //banned IP

    //do something else

}
