$user = $response->getGraphUser();
$fid = $user['id'];
//in mysql table i get 2147483647 in the fid column for the following query
$stmt = $dbh->prepare("INSERT INTO users(fid) VALUES (:fid)");
//in this case $fid not equals $stmt->bindParam(':fid', $fid);
I read this in the Facebook developers documentation:
The id of this person's user account. This ID is unique to each app and cannot be used across different apps. Our upgrade guide provides more information about app-specific IDs
I cannot identify my users when they return on my site and login using Facebook.
Anyone has suggestion?
Thanks in advance,
