Installation
------------

[](#installation)

```
composer require superbalist/php-pubsub-google-cloud
```

Usage
-----

[](#usage)

```
putenv('GOOGLE_APPLICATION_CREDENTIALS=' . __DIR__ . '/../your-gcloud-key.json');

$client = new \Google\Cloud\PubSub\PubSubClient([
    'projectId' => 'your-project-id-here',
]);

$adapter = new \Superbalist\PubSub\GoogleCloud\GoogleCloudPubSubAdapter($client);

// disable auto topic & subscription creation
$adapter->setAutoCreateTopics(false); // this is true by default
$adapter->setAutoCreateSubscriptions(false); // this is true by default

// set a unique client identifier for the subscriber
$adapter->setClientIdentifier('search_service');

// consume messages
// note: this is a blocking call
$adapter->subscribe('my_channel', function ($message) {
    var_dump($message);
});

// publish messages
$adapter->publish('my_channel', 'HELLO WORLD');
$adapter->publish('my_channel', json_encode(['hello' => 'world']));
$adapter->publish('my_channel', 1);
$adapter->publish('my_channel', false);
```

gRPC Support
------------

[](#grpc-support)

Google Cloud PHP v0.12.0 added support for communication over the gRPC protocol.

> gRPC is great for high-performance, low-latency applications, and is highly recommended in cases where performance and latency are concerns.

The library will automatically choose gRPC over REST if all dependencies are installed.

- [gRPC PECL extension](https://pecl.php.net/package/gRPC)
- [google/proto-client-php composer package](https://github.com/googleapis/gax-php)
- [googleapis/proto-client-php composer package](https://github.com/googleapis/proto-client-php)

```
pecl install grpc

composer require google/gax
composer require google/proto-client
```

Background Batch Message Support
--------------------------------

[](#background-batch-message-support)

Google Cloud v0.33.0 added support for queueing messages and publishing in the background. This is available in version 5+ of this package which requires a min version of google/cloud ^0.33.0.

You can enable background batch messaging by setting `$backgroundBatching` to `true` when constructing the `GoogleCloudPubSubAdapter` or by calling `setBackgroundBatching(true)` on an existing adapter.

If the [semaphore](http://php.net/manual/en/book.sem.php) and [pcntl](http://php.net/manual/en/book.pcntl.php) PHP extensions are enabled AND the `IS_BATCH_DAEMON_RUNNING` ENV var is set to `true`, the library will queue messages to be published by the [Batch Daemon](https://github.com/GoogleCloudPlatform/google-cloud-php/blob/master/src/Core/Batch/BatchDaemon.php). The Batch Daemon needs to be manually run as a long-lived background process.

For all other cases, messages will be queued in memory and will be published before the script terminates using a vendor registered shutdown handler.

**Please Note**

This is marked by google/cloud as an experimental feature & may change before release in backwards-incompatible ways.

Examples
--------

[](#examples)

The library comes with [examples](examples) for the adapter and a [Dockerfile](Dockerfile) for running the example scripts.

Run `make up`.

You will start at a `bash` prompt in the `/opt/php-pubsub` directory.

If you need another shell to publish a message to a blocking consumer, you can run `docker-compose run php-pubsub-google-cloud /bin/bash`

To run the examples:

```
$ php examples/GoogleCloudConsumerExample.php
$ php examples/GoogleCloudPublishExample.php (in a separate shell)
```
