How to give multiple files for download?

Question

symfony

I am exporting reports. It is necessary to make sure that the user selects the reports that need to be exported (already implemented) with checkboxes and they are downloaded to his PC. All. You don't need to store them locally on the server.
Everything is implemented except for the file upload itself. There is an associative array with data for export.
Somewhere I heard that you can download 5 files at the same time. Maybe put them in an archive? Have a bundle?

Answer 1

Cross-browser and without unnecessary requests from the user - no way.
It is best to wrap on the server in an archive (zip for example) and give it as an archive.
