Stream large file with Laravel

streamLargeFile.php

<?php
//disable execution time limit when downloading a big file.
set_time_limit(0);

/** @var \League\Flysystem\Filesystem $fs */
$fs = Storage::disk('local')->getDriver();

$fileName = 'bigfile';

$metaData = $fs->getMetadata($fileName);
$stream = $fs->readStream($fileName);

if (ob_get_level()) ob_end_clean();

return response()->stream(
    function () use ($stream) {
        fpassthru($stream);
    },
    200,
    [
        'Content-Type' => $metaData['type'],
        'Content-disposition' => 'attachment; filename="' . $metaData['path'] . '"',
    ]);

Hi! Can you suggest another method that conserves ram usage?
