WordPress on other parts of my site

I have a WordPress installation开发者_如何学Python on my site, and I want to display WP posts on other parts of my site (that is outside the WP installation). How do I do that with PHP?

I tried to search this type of question on Stack Overflow, Google and WP official site but I didn't find anything.

This sites explains how to do it.

Include the wp-blog-header.php from your WP installation. Then you have access to all WordPress functions and the database.
