For Laravel 7.29.3 PHP 7.4.11

Create a GET route in api.php

Route::get('/downloadZip','ZipController@download')->name('download');

Create controller ZipController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use File;

class ZipController extends Controller
{
    public function download(Request $request)
    {
        $zip = new \ZipArchive();
        $fileName = 'zipFile.zip';
        if ($zip->open(public_path($fileName), \ZipArchive::CREATE)== TRUE)
        {
            $files = File::files(public_path('myFiles'));
            foreach ($files as $key => $value){
                $relativeName = basename($value);
                $zip->addFile($value, $relativeName);
            }
            $zip->close();
        }

        return response()->download(public_path($fileName));
    }
}

In the public folder make sure you have a folder myFiles. This snippet will get every file within the folder, create a new zip file and put within the public folder, then when route is called it returns the zip file created.
