如何从Facebook登录获取用户详细信息？

Question

I am using facebook PHP SDK. I need the user to login to my site using their facebook account and I need to store their email, first name and last name in my database. I am using this code to login the user

 $loginUrl   = $facebook->getLoginUrl(
        array(
            'scope'         => 'user_photos,user_videos,email,offline_access,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown',
            'redirect_uri'  => $fbconfig['baseurl']
        )
);

My problem is how can I retrieve the information after the user login and rediret back to my site.

Answer 1

Something along the lines of..

$user = $facebook->getUser();

OR

$user = $facebook->api('/me');

This will return an array that includes all the public information that FB generally gives out. (i.e.- name, birthday, email, etc.)

Now I'm sure you can access the user's email as such,

$userEmail = $user['email'];

To check out everything it returns specifically,

print_r($user);
