Status

This SDK currently supports the following versions of CloudEvents:

• v1.0

Installation

Install the SDK using Composer:

$ composer require cloudevents/sdk-php

Create a CloudEvent

use CloudEvents\V1\CloudEvent;
use CloudEvents\V1\CloudEventImmutable;

// Immutable CloudEvent
$immutableEvent = new CloudEventImmutable(
    '1n6bFxDMHZFChlI4TVI9tdzphB9',
    '/examples/php-sdk',
    'com.example.type',
    ['example' => 'first-event'],
    'application/json'
);

// Mutable CloudEvent
$mutableEvent = new CloudEvent(
    '1n6bFxDMHZFChlI4TVI9tdzphB9',
    '/examples/php-sdk',
    'com.example.type',
    ['example' => 'first-event'],
    'application/json'
);

// Create immutable from mutable or via versa
$event = CloudEventImmutable::createFromInterface($mutableEvent);
$event = CloudEvent::createFromInterface($immutableEvent);

Serialize/Deserialize a CloudEvent

use CloudEvents\Serializers\JsonDeserializer;
use CloudEvents\Serializers\JsonSerializer;

// JSON serialization
$payload = JsonSerializer::create()->serializeStructured($event);
$payload = JsonSerializer::create()->serializeBatch($events);

// JSON deserialization
$event = JsonDeserializer::create()->deserializeStructured($payload);
$events = JsonDeserializer::create()->deserializeBatch($payload);

Marshal/Unmarshal a CloudEvent

use CloudEvents\Http\Marshaller;
use CloudEvents\Http\Unmarshaller;

// Marshal HTTP request
$request = Marshaller::createJsonMarshaller()->marshalStructuredRequest($event);
$request = Marshaller::createJsonMarshaller()->marshalBinaryRequest($event);
$request = Marshaller::createJsonMarshaller()->marshalBatchRequest($events);

// Marshal HTTP response
$request = Marshaller::createJsonMarshaller()->marshalStructuredResponse($event);
$request = Marshaller::createJsonMarshaller()->marshalBinaryResponse($event);
$request = Marshaller::createJsonMarshaller()->marshalBatchResponse($events);

// Unmarshal HTTP message
$events = Unmarshaller::createJsonUnmarshaller()->unmarshal($message);

Community

• There are bi-weekly calls immediately following the Serverless/CloudEvents call at 9am PT (US Pacific). Which means they will typically start at 10am PT, but if the other call ends early then the SDK call will start early as well. See the CloudEvents meeting minutes to determine which week will have the call.

Each SDK may have its own unique processes, tooling and guidelines, common governance related material can be found in the CloudEvents community directory. In particular, in there you will find information concerning how SDK projects are managed, guidelines for how PR reviews and approval, and our Code of Conduct information.
