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
------------

[](#requirements)

- PHP 8.1 - 8.5.

Installation
------------

[](#installation)

The package could be installed with [Composer](https://getcomposer.org):

```
composer require yiisoft/psr-emitter
```

General usage
-------------

[](#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);
```
