Creating a leaderboard using Facebook APIs and the PHP SDK

I'm a new Facebook developer. I'm creating a game and want to include a leader board.

I'd like to build a fairly detailed leader board including the following information:

1) Name 2) Pic_Square or profile_pic 3) A general location (UK, USA or LONDON, NY) 4) Score

I'm aware of how to get a current users basic information from the either the old REST API or the Graph API. However from what I understand of the Facebook rules I can't store the information I want to use from the API.

This lea开发者_JS百科ds me to the conclusion I should be polling the Facebook API using the information I can store (FB user ID's). When querying the API for specific user ID's (the ones for the test users I have generated) API methods (user.getInfo and fql.query) return either just the ID of the user or the fields I have requested with null values.

When querying my own ID I can access all the data.

Are there any methods to obtain publicly available data via the any of the APIs?

Thanks for your help!

Why do you think that you can't store this info? On the user table page it even says:

You can cache this data and subscribe to real time updates on any of its fields which are also fields in the corresponding Graph API version.

If you request offline_access permission you would be able to get user information even when a user is not currently logged in to your app.

You should be able to get any user public info without permissions or access token by going to:

https://graph.facebook.com/<USER_ID>

To display avatar you can use this code:

<img src="https://graph.facebook.com/<USER_ID>/picture"/>

I don't think you would be able to get location without requesting extra permissions.
