facebook, how to get the facebook uid from any facebook page?

how to get the facebook uid off a page, when you visit that page?

if i go to a page of my friend or anybody,开发者_运维知识库 i need to know the uid. i can get mine like this:

$signed_request = $facebook->getSignedRequest();
$user_id = $signed_request['user_id'];

edit: well i have this app and i need to pull the fakebook url into the application so i can grab the id from there. if i try, i get the app id:

$url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; 

what i need is to grab the fb link address,like @Rufinus said, something like https://graph.facebook.com/cocacola

any ideas? thanks

I'm still not 100% on what you're asking. It seems like you're definitely looking to get information about a page as opposed to a user.

If you have an app, on a page in a tab like on the coke page, then we'll pass you a signed request that contains the id of the page. You can then pass that to https://graph.facebook.com/{ID} and you'll get the same result as passing https://graph.facebook.com/{vanityUrl}.

What you want to access from the signed_request is $signed_request['page']['id'].

In that same page array, you can also pull ['page']['liked'] which will tell you if the viewer has liked the page. And finally you can access ['page']['admin'] which will tell you if the viewer is also an admin of that page.

If that doesn't answer your question, edit it a little more and i'll re-answer.

you just can call https://graph.facebook.com/cocacola no token needed.
