Zipping and downloading Amazon S3 bucket files and folders in Laravel - laravel

Question

Is there a way to zip and download files and folders which are in Amazon S3 bucket, together in Laravel? I Want to zip the three folders and one file in the picture together and download it

Answer 1

Here's a half baked solution in a route file. Hope it helps.
https://flysystem.thephpleague.com/docs/adapter/zip-archive/
composer require league/flysystem-ziparchive
I put this in routes/web.php just to play with.
<?php
use Illuminate\Support\Facades\Storage;
use League\Flysystem\Filesystem;
use League\Flysystem\ZipArchive\ZipArchiveAdapter;
Route::get('zip', function(){
// see laravel's config/filesystem.php for the source disk
$source_disk = 's3';
$source_path = '';
$file_names = Storage::disk($source_disk)->files($source_path);
$zip = new Filesystem(new ZipArchiveAdapter(public_path('archive.zip')));
foreach($file_names as $file_name){
$file_content = Storage::disk($source_disk)->get($file_name);
$zip->put($file_name, $file_content);
}
$zip->getAdapter()->getArchive()->close();
return redirect('archive.zip');
});
You'll definitely want to do something different than just plopping it in the public dir. Maybe stream it out straight out as a download or save it somewhere better. Feel free to post comment/questions and we can discuss.

I did it the following way after looking at some solutions by streaming the zip directly to the client by using https://github.com/maennchen/ZipStream-PHP :
if ($uploads) {
return response()->streamDownload(function() use ($uploads) {
$opt = new ArchiveOptions();
$opt->setContentType('application/octet-stream');
$zip = new ZipStream("uploads.zip", $opt);
foreach ($uploads as $upload) {
try {
$file = Storage::readStream($upload->path);
$zip->addFileFromStream($upload->filename, $file);
}
catch (Exception $e) {
\Log::error("unable to read the file at storage path: $upload->path and output to zip stream. Exception is " . $e->getMessage());
}
}
$zip->finish();
}, 'uploads.zip');
}
