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 - 8.5.
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);
