stream-php

stream-php is the official PHP client for Stream, a web service for building scalable newsfeeds and activity streams.

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

You can sign up for a Stream account at https://getstream.io/get_started.

Installation

Composer

composer require get-stream/stream

Composer will install our latest version automatically.

PHP compatibility

Current releases require PHP 7.2 or higher, and depends on Guzzle version 6.

If you need to use the client with PHP 5.4 or earlier versions of Guzzle, you can grab an earlier version of this package:

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

See the Travis configuration 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/.

Quick start

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');

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();

// 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);

// Delete an entire feed and its content
$userFeed->delete();

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.
