Once you have an instance of the Facebook\Facebook service and obtained an access token, you can begin making calls to the Graph API.
In this example we will send a GET request to the Graph API endpoint /me. The /me endpoint is a special alias to the user node endpoint that references the user or Page making the request.
$fb = new Facebook\Facebook([/* . . . */]);
// Sets the default fallback access token so we don’t have to pass it to each request
$fb->setDefaultAccessToken(‘{access-token}’);
try {
$response = $fb->get(‘/me’);
$userNode = $response->getGraphUser();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo ‘Graph returned an error: ‘ . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo ‘Facebook SDK returned an error: ‘ . $e->getMessage();
exit;
}
echo ‘Logged in as ‘ . $userNode->getName();
The get() method will return a Facebook\FacebookResponse which is an entity that represents an HTTP response from the Graph API.
To get the response in the form of a nifty collection, we call getGraphUser() which returns a Facebook\GraphNodes\GraphUser entity which represents a user node.
If you don’t care about fancy collections and just want the response as a plain-old array, you can call the getDecodedBody() method on the FacebookResponse entity.
try {
$response = $fb->get(‘/me’);
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// . . .
exit;
}
$plainOldArray = $response->getDecodedBody();
