Get facebook user if only logged in facebook php sdk

Question

I want to get current loggedin facebook user in php sdk. Here is what i have tried:

$facebook = new \\Facebook(array(
        \'appId\' => \'XXXXXXXXXXX\',
           


        

Answer 1

I get the loginUrl even though I am logged in facebook.

Of course you do – being logged in to facebook.com is something completely different than being logged in to your app.

Only when i load $loginUrl in the browser, I am able to get facebook user.

That’s because after that the user is logged in to your application.

How do I get the current user at first load of this page?

Only possible for users who have connected to your app already at some point before, by using the JavaScript SDK.
