If you want to use somewhere the number of people who likes your fan page, here’s the way to do that:
Create a new basic application from here. Just enter some data and you will receive AppID and Secret keys.
Download the PHP library to work with Facebook API.
git clone https://github.com/facebook/php-sdk.git
require('php-sdk/src/facebook.php'); $facebook = new Facebook(array( 'appId' => '000000000', // put appID here - see Create section 'secret' => '0000c000c000c000c', //put your secret key here - see Create section )); $zt = $facebook->api('/ZeroTurnaround'); // my Facebook page is http://www.facebook.com/ZeroTurnaround echo $zt['likes'];
