Facebook查询语言麻烦 - 试图获取link_stats

So I'm trying to learn how to get link stats for a URL using Facebook's API.

This is what I have here:

    require "application/libraries/facebook.php";

    // Create our Application instance (replace this with your appId and secret).
    $facebook = new Facebook(array(
      'appId'  => 'APP ID WAS HERE',
      'secret' => 'SECRET IS A SECRET',
      'cookie' => true,
    ));

    $fql    =   'SELECT total_count FROM link_stat WHERE url=\"http://google.com\"';
    $param  =   array(
        'method'    => 'fql.query',
        'query'     => $fql,
        'callback'  => ''
    );  
    $fqlResult   =   $facebook->api($param);

That's giving me a blank page. Could it be that I'm not testing this on the website registered with the FB Application?

I'm lost.

Thanks, Dan

use facebook fql console to verify that your fql statement actually works, (say here: http://developers.facebook.com/docs/reference/rest/links.getstats )
