Check if user likes the page in Facebook

Question

I'm trying to check if the user likes the page or not with the following PHP and FQL code:

<?PHP
include 'facebook.php';
$facebook = new Facebook(array(
  'appId'  => 'my_app_ID',
  'secret' => 'my_App_secrert',
));
$user =$facebook->getuser();
$page_id= "200279160150349";
$result = $facebook->api(array(
    "method"    => "fql.query",
    "query"     => "SELECT uid FROM page_fan WHERE uid=$user AND page_id=$page_id"
));
if(count($result))
{
    echo "is a fan!";
}
else
{
echo "Not Fan";
}
?>

Determine that the user is authorized in another page

But always print Not Fan :(

Is user logged via facebook sdk? – JTC Sep 20 '13 at 15:01 — JTC, Sep 20 '13 at 15:01
