Any support requests, bug reports, or development contributions should be directed to that project. A fully-managed real-time messaging service that allows you to send and receive messages between independent applications. ### Installation [](#installation) To begin, install the preferred dependency manager for PHP, [Composer](https://getcomposer.org/). Now install this component: ``` $ composer require google/cloud-pubsub ``` This component supports both REST over HTTP/1.1 and gRPC. In order to take advantage of the benefits offered by gRPC (such as streaming methods) please see our [gRPC installation guide](https://cloud.google.com/php/grpc). ### Authentication [](#authentication) Please see our [Authentication guide](https://github.com/googleapis/google-cloud-php/blob/main/AUTHENTICATION.md) for more information on authenticating your client. Once authenticated, you'll be ready to start making requests. ### Sample [](#sample) ``` use Google\ApiCore\ApiException; use Google\Cloud\PubSub\V1\Client\PublisherClient; use Google\Cloud\PubSub\V1\GetTopicRequest; use Google\Cloud\PubSub\V1\Topic; // Create a client. $publisherClient = new PublisherClient(); // Prepare the request message. $request = (new GetTopicRequest()) ->setTopic($formattedTopic); // Call the API and handle any network failures. try { /** @var Topic $response */ $response = $publisherClient->getTopic($request); printf('Response data: %s' . PHP_EOL, $response->serializeToJsonString()); } catch (ApiException $ex) { printf('Call failed with message: %s' . PHP_EOL, $ex->getMessage()); } ``` ### Debugging [](#debugging) Please see our [Debugging guide](https://github.com/googleapis/google-cloud-php/blob/main/DEBUG.md)for more information about the debugging tools. ### Version [](#version) This component is considered GA (generally available). As such, it will not introduce backwards-incompatible changes in any minor or patch releases. We will address issues and requests with the highest priority. Please see the [migration guide](./MIGRATING.md) to upgrade from **V1** of the library to **V2**. ### Next Steps [](#next-steps) 1. Understand the [official documentation](https://cloud.google.com/pubsub/docs/). 2. Take a look at [in-depth usage samples](https://github.com/GoogleCloudPlatform/php-docs-samples/tree/master/pubsub/). ### Health Score 75 — ExcellentBetter than 100% of packages Maintenance87 Actively maintained with recent releases Popularity63 Solid adoption and visibility Community47 Growing community involvement Maturity91 Battle-tested with a long release history Bus Factor3 3 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
