Now you can run multiple blogs from one installation of WordPress. This new feature is being called Network or Multisite option in WordPress. All you have to open your wp-config.php file located in your WordPress root folder. Then add the following line anywhere in the file:

define('WP_ALLOW_MULTISITE', true);

Find more detail on ” How to enable Multi-Site feature in WordPress 3.0“. After doing this you are able to access the network page from Tools » Network. By default, you are allowed to run other blogs as a subdomain. You can use other domains for blogs by using a Domain Mapping plugin (Detail: How to do Domain Mapping in WordPress Multisite Network).

After converting your WordPress single installation into Multisite Network,  you can do some cool things with it. I will see how to get posts from all blogs in the network.

What if you want to get some recent posts from last updated blogs, not only one blog? Then get_last_updated() is the function that will save your life!

See a simple example that shows the last post from last updated blogs:

$blogs = get_last_updated();
echo '
<h1>Last posts in network</h1>
';
foreach ($blogs AS $blog) {
	echo "
<h2>".$blog["domain"].$blog["path"]."</h2>
";
	switch_to_blog($blog["blog_id"]);
		$lastposts = get_posts('numberposts=1');
		foreach($lastposts as $post) :
			setup_postdata($post);
			the_title();
		endforeach;
	restore_current_blog();
}
