Laravel download base64 encoded files
Laravel has the ability to stream files from disc and remove them as soon as they've been downloaded.
This snippet illustrates this ability. This is useful when you have binanry data that needs storing in order to be emailed and then removed afterwards:
$attachment = EmailAttachment::where('id', $id)->first(); $path = public_path($attachment->name); $contents = base64_decode($attachment->contentBytes); //store file temporarily file_put_contents($path, $contents); //download file and delete it return response()->download($path)->deleteFileAfterSend(true);
