PHP Cloud Functions on Google Cloud Platform with “Functions Framework for PHP”

Google Cloud Platform has launched official support for PHP Cloud Functions using Functions Framework for PHP.

With it, an HTTP Cloud Function becomes as simple as this:

use Psr\Http\Message\ServerRequestInterface;

function helloHttp(ServerRequestInterface $request): string
{
    $queryString = $request->getQueryParams();
    $name = $queryString['name'] ?? $name;

    return sprintf('Hello, %s!', $name);
}

Functions that respond to Cloud Events can work with a \Google\CloudFunctions\CloudEvent instance:

use Google\CloudFunctions\CloudEvent;

function helloworldPubsub(CloudEvent $event): void
{
    $name = 'World';
    $cloudEventData = $event->getData();
    if (!empty($cloudEventData['data'])) {
        $name = base64_decode($cloudEventData['data']);
    }

    // …
}

Installation per Composer

composer require google/cloud-functions-framework
