Updating page status remotely using PHP

I have an online blog that itself is written in PHP. Articles and other functions are published at a predetermined date, which means that I can have 2 months of future content already built and written, which means that the site is constantly updated without my help.

Now I want to be able to update the facebook page associated with the blog automatically. Is it possible to do this? All I want is a new status, which needs to be done every time a new article is published, without having to do it manually.

Any help would be great.
