How to add file from direct download URL ?

[bastien70]

Description of the problem

I've few .pdf links to include to a .zip archive.
The .pdf links are direct download links, so the code I found here doesn't work.
The .zip archive is generated, but with empty files in here

Example code

$response = new StreamedResponse(function () use ($invoicesLines) {
    $options = new Archive();
    $options->setContentType('application/octet-stream');
    // this is needed to prevent issues with truncated zip files
    $options->setZeroHeader(true);

    //initialise zipstream with output zip filename and options.
    $zip = new ZipStream('invoices.zip', $options);

    foreach ($invoicesLines as $invoice) {
        $fp = tmpfile();
        // Download File
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_FILE, $fp);
        curl_setopt($ch, CURLOPT_URL, $invoice->getLink());
        curl_exec($ch);

        // Force to write all data
        fflush($fp);

        // Rewind to the beginning, otherwise the stream is at the end from the start
        rewind($fp);

        // Add File
        $zip->addFileFromStream(sprintf('%s.pdf', $invoice->getNumber()), $fp);

        // Close the Temp File
        fclose($fp);
    }

    $zip->finish();
});

$response->headers->set('Content-Type', 'application/vnd.ms-excel');
$response->headers->set('Content-Disposition', sprintf('attachment;filename="%s"', 'invoices.zip'));
$response->headers->set('Cache-Control', 'max-age=0');

return $response;
