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.

Only pure php code.
public function makeZipWithFiles(string $zipPathAndName, array $filesAndPaths): void {
$zip = new ZipArchive();
$tempFile = tmpfile();
$tempFileUri = stream_get_meta_data($tempFile)['uri'];
if ($zip->open($tempFileUri, ZipArchive::CREATE) !== TRUE) {
echo 'Could not open ZIP file.';
return;
}
// Add File in ZipArchive
foreach($filesAndPaths as $file)
{
if (! $zip->addFile($file, basename($file))) {
echo 'Could not add file to ZIP: ' . $file;
}
}
// Close ZipArchive
$zip->close();
echo 'Path:' . $zipPathAndName;
rename($tempFileUri, $zipPathAndName);
}

I will suggest you to use Zipper package
Try below code for creating zip of multiple files :
public function downloadZip($id)
{
$headers = ["Content-Type"=>"application/zip"];
$fileName = $id.".zip"; // name of zip
Zipper::make(public_path('/documents/'.$id.'.zip')) //file path for zip file
->add(public_path()."/documents/".$id.'/')->close(); //files to be zipped
return response()
->download(public_path('/documents/'.$fileName),$fileName, $headers);
}

you can use the following code
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\ImgUpload;
use ZipArchive;
use File;
class UserController extends Controller
{
/**
* Function to get all images from DB
*/
public function downloadZip()
{
$data = ImgUpload::all();
foreach($data as $key => $value)
{
$imgarr[] = "storage/image". '/' . $value->image;
}
$ziplink = $this->converToZip($imgarr);
return $ziplink;
}
/**
* Function to covert all DB files to Zip
*/
public function converToZip($imgarr)
{
$zip = new ZipArchive;
$storage_path = 'storage/image';
$timeName = time();
$zipFileName = $storage_path . '/' . $timeName . '.zip';
$zipPath = asset($zipFileName);
if ($zip->open(($zipFileName), ZipArchive::CREATE) === true) {
foreach ($imgarr as $relativName) {
$zip->addFile($relativName,"/".$timeName."/".basename($relativName));
}
$zip->close();
if ($zip->open($zipFileName) === true) {
return $zipPath;
} else {
return false;
}
}
}
}

The question got answer, but I am posting this solution for those who wants to download dynamically zip some (based on id) files from the same folder, I hope it might help them that how to create dynamic zip file of multiple files/images affiliated with some id.
I would be taking example of multiple images. You can do the same for files.
Assuming the above table the autos_id is foreign key and based on the autos_id, there are multiple images store in the database.
To make zip file of it I will do the following:
public function downloadZip($id)
{
$data = AutoImage::where('autos_id',$id)->get();
$imgarr=[];
foreach($data as $data){
$file = storage_path() . '/app/public/autoImages/'.$data->image_name;
if(\File::exists(public_path('storage/autoImages/'.$data->image_name))){
$imgarr[]= public_path('storage/autoImages/'.$data->image_name);
}
}
$zip = new ZipArchive;
$fileName = 'AutoImages.zip';
/*OVERWRITE will not make a different zip file on server but it will
replace the one which is in the server, this approach will help you to not
make multiple zip files, if you want to creat new you can do it with unique
name of the zip file and adding CREATE instead of OVERWRITE.*/
if ($zip->open(public_path($fileName), ZipArchive::OVERWRITE) === TRUE)
{
$files = $imgarr; //passing the above array
foreach ($files as $key => $value) {
$relativeNameInZipFile = basename($value);
$zip->addFile($value, $relativeNameInZipFile);
}
$zip->close();
}
return response()->download(public_path($fileName));
}
Note: for file storage I used storage and then made a link symlink for storing files.

This works for me, multiple files zip and download.
public function download_attachment($ticket_no)
{
$zip = new \ZipArchive();
$fileName = $ticket_no.'.zip';
if ($zip->open(public_path($fileName), \ZipArchive::CREATE)== TRUE)
{
$files = File::files(public_path('uploads/tickets/' . $ticket_no));
foreach ($files as $key => $value){
$relativeName = basename($value);
$zip->addFile($value, $relativeName);
}
$zip->close();
}
return response()->download(public_path($fileName));
}
