The package provides a factory to help forming file download PSR-7 response.
- PHP 8.1 or higher.
The package could be installed with composer:
composer require yiisoft/response-download
Use the factory to form a response:
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
{
$steam = new MyStream();
return $this->downloadResponseFactory->sendStreamAsFile($steam, '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.
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
.
