来自部分URL的readfile或类似的东西

Question

First, I know basically zero php, I usually do jsp but I have to modify a footer for a wordpress site we have.

The site currently is hosted at www.mysite.com/wordpress and has the following line:

<?php readfile('http://www.mysite.com/css-imports.jsp'); ?>

and because I am doing this on development I keep having to change it to:

<?php readfile('http://local.mysite.com/css-imports.jsp'); ?>

When I do that the wordpress url is local.mysite.com/wordpress.

How can I from php insert local.mysite.com or www.mysite.com based on the domain that is serving the page?

Thanks.
