I have a simple function, which I'm trying to turn turn into a query. The idea is to grab the number of facebook likes (which I've done), and pass it into a simple equation (which is ready) to work out the percentage of likes against a target number. I know that the php controling the percentage will return 0.0 at the moment - that's fine for now 
I just can't work out how to get from the function to a variable...Code as follows:\[code\]<?php function bfan() {$pageID = 'VisitTywyn';$info = json_decode(file_get_contents('http://graph.facebook.com/' . $pageID));echo $info->likes;} ?><?php bfan(); ?><?phpecho number_format(($num_amount/$num_total)*100, 1);?>\[/code\]Thanks for your help!
