TrueAsync\SendFileOptions
(PHP 8.6+, true_async_server 0.4+)
Value-object con le impostazioni di HttpResponse::sendFile(). Immutabile (final readonly class), si crea tramite argomenti nominati nel costruttore.
php
namespace TrueAsync;
final readonly class SendFileOptions
{
public function __construct(
public ?string $contentType = null,
public SendFileDisposition $disposition = SendFileDisposition::INLINE,
public ?string $downloadName = null,
public ?string $cacheControl = null,
public bool $etag = true,
public bool $lastModified = true,
public bool $acceptRanges = true,
public bool $precompressed = true,
public bool $conditional = true,
public bool $deleteAfterSend = false,
public ?int $status = null,
) {}
}Campi
| Campo | Tipo | Default | Cosa fa |
|---|---|---|---|
contentType | ?string | null | Override del MIME. null: autodetect dall'estensione. |
disposition | SendFileDisposition | INLINE | INLINE: mostra nel browser; ATTACHMENT: download. Influenza Content-Disposition. |
downloadName | ?string | null | Nome file per Content-Disposition: attachment; filename=.... Ha senso con ATTACHMENT. |
cacheControl | ?string | null | Letterale in Cache-Control. null: nessun header. |
etag | bool | true | Emette ETag weak da (mtime_ns, size, ino). |
lastModified | bool | true | Emette Last-Modified (IMF-fixdate). |
acceptRanges | bool | true | Supporto a Range: (HTTP/1.1 partial content). |
precompressed | bool | true | Cerca sidecar (*.br, *.gz, *.zst) se Accept-Encoding lo consente. |
conditional | bool | true | If-Modified-Since / If-None-Match → 304. |
deleteAfterSend | bool | false | unlink($path) dopo invio riuscito. Utile per download one-shot da file temporanei. |
status | ?int | null | Override dello stato HTTP. Esempio: 200 su una risposta in staging specifica, anche se il default sarebbe 304. |
SendFileDisposition
php
namespace TrueAsync;
enum SendFileDisposition: string
{
case INLINE = 'inline';
case ATTACHMENT = 'attachment';
}Esempi
PDF inline
php
use TrueAsync\SendFileOptions;
$res->sendFile('/var/storage/q1-report.pdf', new SendFileOptions(
contentType: 'application/pdf',
cacheControl: 'private, max-age=300',
));Download con nome per l'utente
php
use TrueAsync\SendFileOptions;
use TrueAsync\SendFileDisposition;
$res->sendFile('/var/storage/abc123.bin', new SendFileOptions(
disposition: SendFileDisposition::ATTACHMENT,
downloadName: 'Q1 Report 2026.pdf',
contentType: 'application/pdf',
));File temporaneo one-shot
php
$tmp = '/tmp/export-' . bin2hex(random_bytes(8)) . '.csv';
generateExport($tmp);
$res->sendFile($tmp, new SendFileOptions(
disposition: SendFileDisposition::ATTACHMENT,
downloadName: 'export.csv',
contentType: 'text/csv; charset=utf-8',
deleteAfterSend: true,
));Senza GET condizionali (sempre 200)
php
$res->sendFile('/var/storage/live.mp4', new SendFileOptions(
conditional: false,
acceptRanges: true,
cacheControl: 'no-store',
));Senza sidecar precompresso (lascia comprimere al motore al volo)
php
$res->sendFile('/var/storage/big.json', new SendFileOptions(
precompressed: false,
));
