Pass email and user birthday scope in Facebook Graph API - php

Question

I am new in Facebook Graph API..
I am using this code and it is fetching name and gender perfectly. I want to get email and date of birth from facebook.
<?php
// added in v4.0.0
require_once 'autoload.php';
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\Entities\AccessToken;
use Facebook\HttpClients\FacebookCurlHttpClient;
use Facebook\HttpClients\FacebookHttpable;
// init app with app id and secret
FacebookSession::setDefaultApplication( 'xxxxxx','xxxxxxxxxxxxxxxxxx' );
// login helper with redirect_uri
$helper = new FacebookRedirectLoginHelper('http://www.xxxxxxxxx.com/' );
try {
$session = $helper->getSessionFromRedirect();
}catch( FacebookRequestException $ex ) {
// When Facebook returns an error
}catch( Exception $ex ) {
// When validation fails or other local issues
}
// see if we have a session
if ( isset( $session ) ) {
// graph api request for user data
$request = new FacebookRequest( $session, 'GET', '/me' );
$response = $request->execute();
// get response
$graphObject = $response->getGraphObject();
$fbid = $graphObject->getProperty('id'); // To Get Facebook ID
$fbfullname = $graphObject->getProperty('name'); // To Get Facebook full name
$femail = $graphObject->getProperty('email'); // To Get Facebook email ID
/* ---- Session Variables -----*/
$_SESSION['FBID'] = $fbid;
$_SESSION['FULLNAME'] = $fbfullname;
$_SESSION['EMAIL'] = $femail;
/* ---- header location after session ----*/
header("Location: index.php");
}else {
$loginUrl = $helper->getLoginUrl();
header("Location: ".$loginUrl);
}
?>
Now how I pass email and user birthday scope in my code.
I already take the approval of User birthday and email from facebook viva my APP.

Answer 1

$permissions = ['email', 'user_birthday'];
$loginUrl = $helper->getLoginUrl('http://{your-website}/login-callback.php', $permissions);

Btw, the redirect URL is a required parameter anyway.
