+
+Replace the \$page_id value with your Page ID number (unless you want to show
+the number of fans for this site).You can find your Page ID by logging into your
+Facebook account, going to 'Adverts and Pages', clicking 'Edit page', and
+looking at the URL.
+
+For example, mine is
+<https://www.facebook.com/pages/edit/?id=143394365692197&sk=basic>.
+
+I've also wrapped the output in a number_format() function so that it properly
+formatted with commas etc - like where I've used it within the
+[Gold Event listing](http://www.horseandcountry.tv/events/paid) on the Horse &
+Country TV website.
+
+```language-php
+$page_id = "143394365692197";
+$xml = @simplexml_load_file("http://api.facebook.com/restserver.php?method=facebook.fql.query&amp;query=SELECT%20fan_count%20FROM%20page%20WHERE%20page_id=".$page_id."") or die ("a lot");
+$fans = $xml->page->fan_count;
+print number_format($fans);
+```
