Facebook SDK error 'Required "app_id" key not supplied in config

I have implemented login system that return access token on my application end using facbook graph api. But while I tried to user information using following scripts I am getting error.

My scripts:

require_once __DIR__ . '/facebook-php-sdk-v4-5.0-dev/src/Facebook/autoload.php';
$fb = new Facebook\Facebook([
'appId'  => 'appid',
'secret' => 'secret',
'default_graph_version' => 'v2.2'
    ]);
try {
 // Returns a `Facebook\FacebookResponse` object
 $response = $fb->get('/me?fields=id,name', 'some access token');
} catch(Facebook\Exceptions\FacebookResponseException $e) {
 echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
 echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}

 $user = $response->getGraphUser();

 echo 'Name: ' . $user['name'];

Error experienced:

   Fatal error: Uncaught exception 'Facebook\Exceptions\FacebookSDKException' with message 'Required "app_id" key     not supplied in config and could not find fallback environment variable   "FACEBOOK_APP_ID"' in B:\xampp\htdocs\SocialAPI\facebook-php-sdk-v4-5.0-   dev\src\Facebook\Facebook.php:133 Stack trace: #0    B:\xampp\htdocs\SocialAPI\loginSuccess.php(22): Facebook\Facebook->__construct(Array) #1 {main} thrown in B:\xampp\htdocs\SocialAPI\facebook-php-  sdk-v4-5.0-dev\src\Facebook\Facebook.php on line 133

It's seems that your Facbook.php file expecting app_id instead of appId

In order to resolve at first open your following file:

B:\xampp\htdocs\SocialAPI\facebook-php-sdk-v4-5.0-   dev\src\Facebook\Facebook.php

Then look for appId whether exist or not. If not appId not found then update your config as following: 

$fb = new Facebook\Facebook([
'app_id'  => 'appid',
'secret' => 'secret',
'default_graph_version' => 'v2.2'
]);

If your issue doesn't resolve please let know.
