Ably

A PHP REST client library for www.ably.io, the realtime messaging service. This library currently targets the Ably 1.1 client library specification. You can jump to the 'Known Limitations' section to see the features this client library does not yet support or view our client library SDKs feature support matrix to see the list of all the available features.

Supported Platforms

This SDK supports PHP 5.6 and 7.0+

We regression-test the library against a selection of PHP versions (which will change over time, but usually consists of the versions that are supported upstream). Please refer to .travis.yml for the set of versions that currently undergo CI testing.

We'll happily support (and investigate reported problems with) any reasonably-widely-used PHP version. If you find any compatibility issues, please do raise an issue in this repository or contact Ably customer support for advice.

Known Limitations

Currently, this SDK only supports Ably REST. However, you can use the MQTT adapter to implement Ably's Realtime features using Python.

This SDK is not compatible with some of the Ably features:

Feature
Remember fallback host during failures
MsgPack Binary Protocol

Installation

Via composer

The client library is available as a composer package on packagist. If you don't have composer already installed, you can get it from https://getcomposer.org/.

Install Ably from the shell with:

$ composer require ably/ably-php --update-no-dev

Then simply require composer's autoloader:

require_once __DIR__ . '/vendor/autoload.php';

Manual installation

Clone or download Ably from this repo and require ably-loader.php:

require_once __DIR__ . '/ably-php/ably-loader.php';

Using the REST API

Introduction

All examples assume a client and/or channel has been created as follows:

$client = new Ably\AblyRest('your.appkey:xxxxxx');
$channel = $client->channel('test');

Publishing a message to a channel

$channel->publish('myEvent', 'Hello!'); // => true

Querying the History

$messagesPage = $channel->history(); // => \Ably\Models\PaginatedResult
$messagesPage->items[0]; // => \Ably\Models\Message
$messagesPage->items[0]->data; // payload for the message
$messagesPage->next(); // retrieves the next page => \Ably\Models\PaginatedResult
$messagesPage->hasNext(); // false, there are no more pages

Presence on a channel

$membersPage = $channel->presence->get(); // => \Ably\Models\PaginatedResult
$membersPage->items[0]; // first member present in this page => \Ably\Models\PresenceMessage
$membersPage->items[0]->clientId; // client ID of first member present
$membersPage->next(); // retrieves the next page => \Ably\Models\PaginatedResult
$membersPage->hasNext(); // false, there are no more pages

Querying the Presence History

$presencePage = $channel->presence->history(); // => \Ably\Models\PaginatedResult
$presencePage->items[0]; // => \Ably\Models\PresenceMessage
$presencePage->items[0]->clientId; // client ID of first member
$presencePage->next(); // retrieves the next page => \Ably\Models\PaginatedResult

Generate Token and Token Request

$tokenDetails = $client->auth->requestToken();
// => \Ably\Models\PresenceMessage
$tokenDetails->token; // => "xVLyHw.CLchevH3hF....MDh9ZC_Q"

$client = new Ably\AblyRest( $tokenDetails->token );
// or
$client = new Ably\AblyRest( array( 'tokenDetails' => $tokenDetails ) );

$token = $client->auth->createTokenRequest();
// => {"id" => ...,
//     "clientId" => null,
//     "ttl" => 3600,
//     "timestamp" => ...,
//     "capability" => "{\"*\":[\"*\"]}",
//     "nonce" => ...,
//     "mac" => ...}

Fetching your application's stats

$statsPage = client->stats(); // => \Ably\Models\PaginatedResult
$statsPage->items[0]; // => \Ably\Models\Stats
$statsPage->next(); // retrieves the next page => \Ably\Models\PaginatedResult

Fetching the Ably service time

$client->time(); // in milliseconds => 1430313364993

You can also view the community reported Github issues.

To see what has changed in recent versions of Bundler, see the CHANGELOG.

Known limitations

1. This client library requires PHP version 5.4 or greater
2. msgpack support is currently missing in PHP client library, as there is no stable PHP msgpack library available.

Running the tests

The client library uses the Ably sandbox environment to provision an app and run the tests against that app. In order to run the tests, you need to:

git clone https://github.com/ably/ably-php.git
cd ably-php
composer install
git submodule init
git submodule update
./vendor/bin/phpunit

Contributing

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Ensure you have added suitable tests and the test suite is passing (run vendor/bin/phpunit)
5. Push to the branch (git push origin my-new-feature)
6. Create a new Pull Request

Release Process

This library uses semantic versioning. For each release, the following needs to be done:

• Update the version number in src/AblyRest.php
• Run github_changelog_generator to automate the update of the CHANGELOG. Once the CHANGELOG update has completed, manually change the Unreleased heading and link with the current version number such as 1.0.0. Also ensure that the Full Changelog link points to the new version tag instead of the HEAD.
• Commit
• Add a tag and push to origin such as git tag 1.0.0 && git push origin 1.0.0
• Visit https://github.com/ably/ably-php/tags and add release notes for the release including links to the changelog entry.
• Visit https://packagist.org/packages/ably/ably-php, log in to Packagist, and click the "Update" button.
• Remember to release an update for the PHP Laravel library
