I am following the example at <https://getstream.io/get_started/?language=php> to understand how getstream io works. I ran into an error that got me confused.

```
 require_once './vendor/autoload.php';
 $client = new GetStream\Stream\Client('YOUR_API_KEY',     'API_KEY_SECRET');
$chris = $client->feed('user', 'chris');
 // I replaced Your api key and api key secret with the one         in my dashboard
// Add an activity; message is a custom field - tip: add unlimited         custom fields!
$data = array(
"actor" => "chris",
"verb" => "add",
"object" => "picture:10",
"foreign_id" => "picture:10",
"message" => "Beautiful bird. Absolutely beautiful. Phenomenal bird."
);

$chris->addActivity($data);

// jack's 'timeline' feed follows chris' 'user' feed:
$jack = $client->feed('timeline', 'jack');
$jack->followFeed('user', 'chris');

// Read the 'timeline' feed for jack, chris' post will now show up: 
$activities = $jack->getActivities(10);
var_dump($activities);

```

In my composer.json file I did this

```
       "require": {
        "get-stream/stream": "2.2.8"
        }

```

I tried the above code on my localhost machine on windows but got this error

```
