How to show only blog-domain instead of the whole permalink in the loop

Question

I wanna show the blog URL instead of the whole post URL in my loop.

The reason is that I use Wordpress multiblog with sitewide tags, so on my front-page of the main blog I'm showing the 10 last posts globally. I wanna show the blogdomain the post is coming from.

the_permalink works if I wanna show the whole post-url but I need to cut it down to show only the domain.

Can anyone help me?

Answer 1

Use parse_url():

echo parse_url( get_permalink(), PHP_URL_HOST );

Answer 2

I think your looking for the function get_site_url( $blog_id );

$blog_id is the ID of the blog where your post is from.
