如何使用我的长（60天）访问令牌从Facebook获取用户数据（离线）

Question

I cannot find any example on facebook dev. or here on stackoverflow so I need to make this post which i didn't thought i had to.

I have a website which uses the facebook JavaScript SDK to login users into it. When I log in users I uses the

FB.login(), scope:{'email, offline_access'}

When the login in done i get the short lived access token and passes it to:

https://graph.facebook.com/oauth/access_token?  
    grant_type=fb_exchange_token&           
    client_id=APP_ID&
    client_secret=APP_SECRET&
    fb_exchange_token=SHORT_LIVED_ACCESS_TOKEN 

So i get the long lived, 60day, token in response. This is done server-side and i save the new long lasting token in my database along with facebook id etc.

Now to my problem. Every day at a certain time I want to update the users data in my database using the access token, which i have read that could. But how do i do that?

I'm used to do like this after the FB.login() but now when the user do not login I don't know how to do the call to FB.api using my persisted token?

FB.api(/me....)

As you have to synchronize/update information when user is not logged in you will have to use server side interaction. You may use your saved Extended Access Token and set it into Facebook PHP SDK using setAccessToken() method.

$facebook->setAccessToken($extended_access_token);

After this you may call $facebook->api(...) method to perform the task that you intend to.
