The package provides a factory to help forming file download PSR-7 response.

## Requirements

- PHP 8.1 or higher.

## Installation

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

```shell
composer require yiisoft/response-download
```

## General usage

Use the factory to form a response:

```php
use Psr\Http\Message\ResponseInterface;
use Yiisoft\ResponseDownload\DownloadResponseFactory;

final class MyController
{
public function __construct(
private readonly DownloadResponseFactory $downloadResponseFactory,
)
{
}

public function sendMyContentAsFile(): ResponseInterface
{
return $this->downloadResponseFactory->sendContentAsFile('Hello!', 'message.txt');
}

public function sendMyFile(): ResponseInterface
{
return $this->downloadResponseFactory->sendFile('message.txt');
}

public function xSendMyFile(): ResponseInterface
{
return $this->downloadResponseFactory->xSendFile('message.txt');
}

public function sendMyStreamAsFile(): ResponseInterface
{
$stream = new MyStream();

return $this->downloadResponseFactory->sendStreamAsFile($stream, 'message.txt');
}
}
```

Note the `xSendFile()`. It is a special method that delegates the hard work to the web server instead of serving the
file using PHP.

Optional arguments and defaults:

- If attachment name is not specified in `sendFile()` or `xSendFile()`, it will be taken from the name of the file
- served.
- Each file sending method could also be provided with optional mime type and optional content disposition.
- If mime type is omitted, for `sendFile()` and `xSendFile()` it will be determined based on the file content.
For other methods or when unable to determine the mime type, "application/octet-stream" will be used.
- Content disposition is "attachment" by default. It will trigger browser's download dialog. If you want the content
of the file to be displayed inline, set it to `Yiisoft\Http\ContentDispositionHeader\ContentDispositionHeader::INLINE`.
