📝 About Stream

💡 Note: this is a library for the Feeds product. The Chat SDKs can be found here.

You can sign up for a Stream account at our Get Started page.

You can use this library to access Feeds API endpoints server-side.

For the client-side integrations (web and mobile) have a look at the JavaScript, iOS and Android SDK libraries (docs).

💡 Note: there is also a higher level Laravel integration which hooks into the Eloquent ORM.

⚙️ Installation

$ composer require get-stream/stream

Composer will install our latest version automatically.

PHP compatibility

Current releases require PHP 7.3 or higher, and depends on Guzzle version ^6.3.3.

If you need to use the client with an old PHP or earlier versions of Guzzle, you can grab an earlier version of this package, for example:

$ composer require get-stream/stream:"~2.1.0"

See the action for details of how it is built and tested against different PHP versions.

📚 Documentation

Our full documentation for this package is available at https://getstream.io/docs/php/.

✨ Getting started

First, signup here for a free account and grab your API key and secret.

Initiating a Client and a Feed object:

// Instantiate a new client, find your API keys in the dashboard.
$client = new GetStream\Stream\Client('YOUR_API_KEY', 'YOUR_API_SECRET');

// Instantiate a feed object
$userFeed = $client->feed('user', '1');

// If you want, you can set a custom http handler
$handler = new \GuzzleHttp\HandlerStack();
$stack->push(Middleware::mapRequest(function (RequestInterface $r) {
    echo 'Sending request to Stream Feeds API: ' . $r->getUri() . PHP_EOL;
    return $r;
}));
$client->setCustomHttpHandler($handler);

By default, the Client will target the GetStream REST API at stream-io-api.com/api. If you want to change this for some reason you can set the STREAM_BASE_URL environment variable.

Activities in a feed:

// Create a new activity
$data = [
    'actor' => '1',
    'verb' => 'like',
    'object' => '3',
    'foreign_id' => 'like:42',
];

$response = $userFeed->addActivity($data);

// The response will include Stream's internal ID:
// {"id": "e561...", "actor": "1", ...}

// Get the latest activities for this user's personal feed, based on who they are following.
$response = $userFeed->getActivities();

// Get activities directly by their ID or combination of foreign ID and time.
$response = $client->getActivitiesById(['74b9e88a-a684-4197-b30c-f5e568ef9ae2', '965f7ba5-8f1d-4fd1-a9ee-22d1a2832645']);
$response = $client->getActivitiesByForeignId(['fid:123', '2006-01-02T15:04:05.000000000'], ['fid:456', '2006-01-02T16:05:06.000000000']);

// The response will be the json decoded API response.
// {"duration": 45ms, "next": "/api/v1.0/feed/...", "results": [...]}

// Remove an activity by its ID
$userFeed->removeActivity('e561de8f-00f1-11e4-b400-0cc47a024be0');

// To remove activities by their foreign_id, set the "foreign id" flag to true.
$userFeed->removeActivity('like:42', true);

Following/follower relations of a feed:

// When user 1 starts following user 37's activities
$userFeed->follow('user', '37');

// When user 1 stops following user 37's activities
$userFeed->unfollow('user', '37');

// Retrieve followers of a feed
$userFeed->followers();

// Retrieve feeds followed by $userFeed
$userFeed->following();

Advanced activity operations:

// Create a bit more complex activity with custom fields
$data = [
    'actor' => 1,
    'verb' => 'run',
    'object' => 1,
    'foreign_id' => 'run:42',

    // Custom fields:
    'course' => [
        'name'=> 'Golden Gate park',
        'distance'=> 10,
    ],
    'participants' => ['Thierry', 'Tommaso'],
    'started_at' => new DateTime('now', new DateTimeZone('Pacific/Nauru'),
];

// Add an activity and push it to other feeds too using the `to` field
$data = [
    'actor' => '1',
    'verb' => 'like',
    'object' => '3',
    'to' => [
        'user:44',
        'user:45',
    ],
];

$userFeed->addActivity($data);

// Batch adding activities
$activities = [
    ['actor' => '1', 'verb' => 'tweet', 'object' => '1'],
    ['actor' => '2', 'verb' => 'like', 'object' => '3'],
];

$userFeed->addActivities($activities);

Advanced batching:

// Batch operations (batch activity add, batch follow)
$batcher = $client->batcher();

// Add one activity to many feeds
$activity = ['actor' => '1', 'verb' => 'tweet', 'object' => '1'];
$feeds = ['user:1', 'user:2'];

$batcher->addToMany($activity, $feeds);

// Create many follow relations
$follows = [
    ['source' => 'user:b1', 'target' => 'user:b2'],
    ['source' => 'user:b1', 'target' => 'user:b3'],
];

$batcher->followMany($follows);

Generating tokens for client-side usage:

// Generating a user token
$userToken = $client->createUserSessionToken("the-user-id");

RateLimits:

If your app hits a ratelimit, a StreamFeedException is thrown. You can get additional info by catching the exception and calling the following methods:

try {
    $client->updateActivity($activity);
}catch(StreamFeedException $e){
    $limit = $e->getRateLimitLimit();
    $remaining = $e->getRateLimitRemaining();
    $reset = $e->getRateLimitReset(); // a unix timestamp
}

Reactions:

The reactions module has the following methods.

- add(string $kind, string $activityId, string $userId, array $data=null, array $targetFeeds=null)
- addChild(string $kind, string $parentId, string $userId, array $data=null, array $targetFeeds=null)
- delete(string $reactionId)
- filter(string $lookupField, string $lookupValue, string $kind=null, array $params=null)
- get(string $reactionId)
- update(string $reactionId, array $data=null, array $targetFeeds=null)

Also see documention on the reactions endpoint

$reaction = $client->reactions()->add('like', $activity_id, 'bob');

$bob_likes = $client->reactions()->filter('user_id', 'bob', 'like');

$client->reactions()->delete($reaction['id']);

Users:

The users module has the following methods.

- add(string $userId, array $data=null, bool $getOrCreate=false)
- createReference(string $userId)
- delete(string $userId)
- get(string $userId)
- update(string $userId, array $data=null)

Also see documention on the users endpoint

$user = $client->users()->add('42');

$user =  $client->users()->update('42', array('name' => 'Arthur Dent');

$client->users()->delete('42');

Again, our full documentation with all options and methods, is available at https://getstream.io/docs/php/.

☯️ Framework integration

Laravel

There's a higher level integration with Laravel called get-stream/stream-laravel. The stream-laravel integration helps you to hook into the Laravel's Eloquent ORM to sync data to Stream.
