README

Yii PSR Emitter

The package provides EmitterInterface that is responsible for sending PSR-7 HTTP responses as well as several implementations of the interface:

• SapiEmitter - sends a response using standard PHP Server API;
• FakeEmiiter - a fake emitter that does nothing, except for capturing response (useful for testing purposes).

Additionally, the package provides EmitterMiddleware PSR-15 middleware that can be used in an application to send a response by any EmitterInterface implementation.

Requirements

• PHP 8.1 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/psr-emitter

General usage

Create emitter instance and call emit() method with a PSR-7 response:

use Psr\Http\Message\ResponseInterface;
use Yiisoft\PsrEmitter\SapiEmitter;

/** @var Response $response */

$emitter = new SapiEmitter();
$emitter->emit($response);

You can customize the buffer size (by default, 8MB) for large response bodies:

use Psr\Http\Message\ResponseInterface;
use Yiisoft\PsrEmitter\SapiEmitter;

/** @var Response $response */

$emitter = new SapiEmitter(4_194_304); // Buffer size is 4MB

// Response content will be sent in chunks of 4MB
$emitter->emit($response);
