Are facebook notifications from either vb.net or PHP? - php

Question

Does anyone know if its possible to create a Facebook notification either via Vb.Net or PHP using the Facebook SDK version 4.
Ideally I'd like to have users on my website enter their Facebook login details which I'd then store their [facebook id] so I could send a weekly status notification via VB.Net to their Facebook account.
Edited
So far I get the scope ID from javascript and for testing copy it to PHP
<?php
$appId = '77585851581xxxx';
$appSecret = 'xxxx';
$userId = '1015273548332xxxx'; //Scope ID
$accesstoken = $appId . '|' . $appSecret;
$notificationText = 'The cake is a lie.';
//Get Access Token
$args = array('grant_type' => 'client_credentials',
'client_id' => $appId,
'client_secret' => $appSecret);
$ch = curl_init();
$url = 'https://graph.facebook.com/oauth/access_token';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$returnValue = curl_exec($ch);
curl_close($ch);
echo $returnValue;
$accesstoken = $returnValue;
//Set Notification
$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, 'facebook');
$url = 'https://graph.facebook.com/' . $userId . '/notifications' .
'?access_token=' . $accesstoken .
'&template=' . $notificationText .
'&href=';
curl_setopt($ch, CURLOPT_URL, $url);
$curlResult = curl_exec($ch);
echo $curlResult;
?>
I now get the error:
Sorry, something went wrong. We're working on getting this fixed as soon as we can.

Tutorial for the PHP SDK 4.0: http://www.devils-heaven.com/facebook-php-sdk-4-0-tutorial/
Although i would suggest using simple CURL calls for App Notifications, you don´t need the PHP SDK for that. Example code can be found here: http://blog.limesoda.com/2014/08/app-notifications-facebook-apps/
The article is in german, but the code is the relevant part:
$accessToken = $appId . '|' . $appSecret;
$notificationText = 'The cake is a lie.';
//init curl
$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, 'facebook');
//send notification
$url = 'https://graph.facebook.com/' . $userId . '/notifications' .
'?access_token=' . $accesstoken .
'&template=' . $notificationText .
'&href=';
curl_setopt($ch, CURLOPT_URL, $url);
$curlResult = curl_exec($ch);
