I have developed a digital asset manager using Laravel 10. When the user downloads more that one asset i create a zip file and use laravel’s response()->download() function to download it. Here is the function.

`
public function downloadAssets(Request $request){
$assetIds = $request->input(‘assetIds’);

    // Create a temporary zip file
    $zipFileName = time().'_assets'.'.zip';
    $zipFilePath = storage_path('app/public/images/archive/original/' . $zipFileName);

    $zip = new ZipArchive;
    $zip->open($zipFilePath, ZipArchive::CREATE);
    
    foreach($assetIds as $assetId){
        $asset = Asset::find($assetId);
        if(str_starts_with($asset->type, 'image/svg')){
            $filePath = storage_path('app/public/images/archive/svg/'.$asset->filename);
        }
        elseif(str_starts_with($asset->type, 'video')){
            $filePath = storage_path('app/public/videos/original/'.$asset->filename);
        }
        else{
            $filePath = storage_path('app/public/images/archive/original/'.$asset->filename);
        }
        

        $zip->addFile($filePath, $asset->filename);
    }

    $zip->close();

    $headers = [
        'Content-Type' => 'application/zip',
    ];

    $response = response()->download($zipFilePath, $zipFileName, $headers);
        
    return $response;
}

`

The problem is that if i open the file i get the error in windows “The archive is either in unknown format or damaged”.

I tried downloading the file with ftp and had no problems. I also had not problems downloading the file from the browser by hitting the url or the file.

I tried adding 'Content-Disposition' => 'attachment; filename="' . $zipFileName . '"', in the headers and it didn’t work. I also trying adding ob_clean() and it didn’t work.
