gather Facebook Group feed and display on website

I am admin of a FB group with intense activity and I want to take the generated content ( topics with replies ) and display them in a page on my website, with daily refresh. The content does not have to be interactive on the website. The website is a simple plain html, not based on a CMS. The script that gathers the FB feed should be PHP, the content should be stored in a MySQL db ( that you design ) and the display should be done through a PHP script that you develop. The visual style of the page should follow the style elements of the website.
