UPDATE 2:
To check if the current user is a fan of the Facebook page on landing at your tab check this answer.
更新 2：
要检查当前用户是否是登陆您的标签时 Facebook 页面的粉丝，请检查此答案。
UPDATE:
You can use the likesconnection to check if a user is a fan of a page:
更新：
您可以使用likes连接来检查用户是否是某个页面的粉丝：
https://graph.facebook.com/me/likes/PAGE_ID
&access_token=ACCESS_TOKEN
This would return either an empty data array:
这将返回一个空数据数组：
Array
(
[data] => Array
(
)
)
Or if fan:
或者如果风扇：
Array
(
[data] => Array
(
[0] => Array
(
[name] => Real Madrid C.F.
[category] => Professional sports team
[id] => 19034719952
[created_time] => 2011-05-03T20:53:26+0000
)
)
)
So this is how we check using the PHP-SDK:
所以这就是我们如何使用 PHP-SDK 检查：
<?php
require '../src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'APP_ID',
'secret' => 'APP_SECRET',
));
$user = $facebook->getUser();
if ($user) {
try {
$likes = $facebook->api("/me/likes/PAGE_ID");
if( !empty($likes['data']) )
echo "I like!";
else
echo "not a fan!";
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'user_likes'
));
}
// rest of code here
?>
Similar script usingJS-SDK:
使用JS-SDK的类似脚本：
FB.api('/me/likes/PAGE_ID',function(response) {
if( response.data ) {
if( !isEmpty(response.data) )
alert('You are a fan!');
else
alert('Not a fan!');
} else {
alert('ERROR!');
}
});
// function to check for an empty object
function isEmpty(obj) {
for(var prop in obj) {
if(obj.hasOwnProperty(prop))
return false;
}
return true;
}
Code taken from my tutorial.
代码取自我的教程。
While pages.isFanis still working for me, you can use the FQL page_fantable with the new PHP-SDK:
虽然pages.isFan仍在为我工作，但您可以将 FQLpage_fan表与新的 PHP-SDK 一起使用：
$result = $facebook->api(array(
"method" => "fql.query",
"query" => "SELECT uid FROM page_fan WHERE uid=$user_id AND page_id=$page_id"
));
if(!empty($result)) // array is not empty, so the user is a fan!
echo "$user_id is a fan!";
From the documentation:
从文档：
To read the page_fan table you need:
- any valid
access_tokenif it is public (visible to anyone on Facebook).user_likespermissions if querying the current user.friends_likespermissions if querying a user's friend.
要阅读 page_fan 表，您需要：
- 任何有效，
access_token如果它是公开的（Facebook 上的任何人都可以看到）。user_likes如果查询当前用户，则权限。friends_likes如果查询用户的朋友，则权限。

Here's another approachthat relies on the signed_request POST variable that Facebook sends to every tab app page (if you have the "OAuth 2.0 for Canvas" advanced option turned on.
这是另一种方法，它依赖于 Facebook 发送到每个标签应用程序页面的 signed_request POST 变量（如果您打开了“OAuth 2.0 for Canvas”高级选项。
The nice thing about this is you don't need to send another fql.query.
这样做的好处是您不需要发送另一个 fql.query。

Or you can use fbml if you whant for example show some content if they are fan or made some dinamic stuff.
或者你可以使用 fbml，如果你想显示一些内容，如果他们是粉丝或制作了一些动态的东西。
example:
例子：
<fb:fbml version="1.1">
<fb:visible-to-connection>This part is visible for fans only!
<fb:else>This part is visible for non-fans</fb:else>
</fb:visible-to-connection>
</fb:fbml>
