The Facebook LIKE Counter is a simple JavaScript driven HTML dashboard that show's a live count of likes for a given URL.
It does the work of combining counts for www. and non-www. URL's so that you get a full picture of how people are sharing and liking your URL.
Simply put the index.php file in a sub-folder of your website (i.e. http://example.com/facebookcounter/) and load that page in your browser.
All you need to do is copy a URL into the text-field at the top of the page, hit enter, and the page will display the number of times your URL has been liked. The count will update every 10 seconds.
