How to Add Wordpress Posts into Your Main Site Index

As the title says, how one can add wordpress posts into their main site index. For example, if your website's main index is on a different CMS than wordpress and you host a wordpress blog at a subdomain/folder level and also want the new posts to be shown at front page of your main index, which is not wordpress, what would you do? Any help shall be appreciated.

Thanks

 

RSS feeds? Not sure since it's on a different CMS. Never done it that way before.

 

I have seen this on several sites, so its sure that its possible.

 

There are several ways you can do it:
1. Use an RSS reader script that gets the Wordpress feed.
2. Get the posts using Wordpress functions, as explained in this article.
3. Get the posts directly from the Wordpress database, which is definitely the hardest way.

Easiest way is to use the RSS feed, unless you need specific posts.

 

I use RSS feeds. There has to be a plugin that can do this for you, or some kind of widget.
