Birthday for the Facebook SDK for PHP

Extends \DateTime and represents a user's birthday returned from the Graph API which can be returned omitting certain information.

Users may opt not to share birth day or month, or may not share birth year. Possible returns:

• MM/DD/YYYY
• MM/DD
• YYYY

Facebook\GraphNode\Birthday

After retrieving a GraphUser from the Graph API, the getBirthday() method will return the birthday in the form of a Facebook\GraphNode\Birthday entity which indicates which aspects of the birthday the user opted to share.

The Facebook\GraphNode\Birthday entity extends DateTime so format may be used to present the information appropriately depending on what information it contains.

Usage:

$fb = new Facebook\Facebook(\* *\);
// Returns a `Facebook\Response` object
$response = $fb->get('/me');

// Get the response typed as a GraphUser
$user = $response->getGraphUser();

// Gets birthday value, assume Graph return was format MM/DD
$birthday = $user->getBirthday();

var_dump($birthday);
// class Facebook\GraphNode\Birthday ...

var_dump($birthday->hasDate());
// true

var_dump($birthday->hasYear());
// false

var_dump($birthday->format('m/d'));
// 03/21
