Shows :Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. thrown in C:\wamp\www\fb\facebook_php_sdk\src\base_facebook.php on line 1106

Answer 1

You must have access token for this operation.
First you request for access token like this:

$my_access_token=$facebook->getAccessToken();

Then you can request for friend list like this:

try {

$friends = $facebook->api('/me/friends',array('access_token'=>$my_access_token));
} catch (FacebookApiException $e) {

error_log($e);
}

This might work. I this works,then accept this answer!
Happy Coding!
