Facebook PHP SDK (v.3.0.0)
|
|||
|
|
==========================
|
|||
|
|
|
|||
|
|
The new PHP SDK (v3.0.0) is a major upgrade to the older one (v2.2.x):
|
|||
|
|
|
|||
|
|
- Uses OAuth authentication flows instead of our legacy authentication flow
|
|||
|
|
- Consists of two classes. The first (class BaseFacebook) maintains the core of the upgrade, and the second one (class Facebook) is a small subclass that uses PHP sessions to store the user id and access token.
|
|||
|
|
|
|||
|
|
If you’re currently using the PHP SDK (v2.2.x) for authentication, you will recall that the login code looked like this:
|
|||
|
|
|
|||
|
|
$facebook = new Facebook(…);
|
|||
|
|
$session = $facebook->getSession();
|
|||
|
|
if ($session) {
|
|||
|
|
// proceed knowing you have a valid user session
|
|||
|
|
} else {
|
|||
|
|
// proceed knowing you require user login and/or authentication
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
The login code is now:
|
|||
|
|
|
|||
|
|
$facebook = new Facebook(…);
|
|||
|
|
$user = $facebook->getUser();
|
|||
|
|
if ($user) {
|
|||
|
|
// proceed knowing you have a logged in user who's authenticated
|
|||
|
|
} else {
|
|||
|
|
// proceed knowing you require user login and/or authentication
|
|||
|
|
}
|
