使用Facebook PHP SDK返回用户数据

Question

I'm trying to figure out the basics of the facebook php sdk. I'm using the pretty simple code below...

<?php

include 'facebook.php';
$app_id = "my_id";
$app_secret = "my_secret";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,

));


$userId = $facebook->getUser();

echo $userId;

$userInfo = $facebook->api("/$userId"); 

echo $userInfo['name'];

?>

When I ask for the $userId with

$userId = $facebook->getUser();

echo $userId;

I get the correct value. However when I try to take the next step and retrieve the logged in user's name with :

$userInfo = $facebook->api("/$userId"); 

echo $userInfo['name'];

nothing is returned. Does anyone see my error? Thanks!

'/$userId' will actually use the literal string /$userId . You probably want "/$userId" or '/me'
