Zip upload with validations in Laravel

Following code is for unzipping files, then validating and lastly saving in the database.

public function unzip_contents_gallery(Request $request)
    {
        try{
            $v = [];
            $allowed_exts = [
                'png',
                'jpeg',
                'jpg',
                'webp',
            ];
            $zip = new ZipArchive();
            $status = $zip->open($request->file("zip_gallery")->getRealPath());

            if ($status !== true) 
                throw new Exception('Un-supported zip archive');

            for($i=0; $i<$zip->count();$i++)
            {
                array_push($v, ['name' => $zip->getNameIndex($i)]);
                $ext_name_arr = explode('.', $zip->getNameIndex($i));
                if(!(in_array(end($ext_name_arr), $allowed_exts)))
                    throw new Exception('File not supprted!');
            } 
            $rules = [
                '*.name' => 'required|unique:galleries,gallery',
            ];
            $validator = Validator::make($v, $rules);
            if($validator->fails()) 
                throw new Exception(json_encode($validator->errors()->all()));
                // throw new Exception($validator->errors()->first());

            $storageDestinationPath = public_path('uploads/gallery_images');
            if (!\File::exists( $storageDestinationPath)) {
                \File::makeDirectory($storageDestinationPath, 0755, true);
            }
            $zip->extractTo($storageDestinationPath);
            $zip->close();
            for($i=0; $i<count($v);$i++)
            {
                Gallery::create([
                    'gallery' =>  $v[$i]
                ]);
            } 

            $msg = "File Upload Successfully";
            return redirect()->back()->withSuccess($msg);
        }
        catch(Exception $e)
        {
            return redirect()->back()->withErrors($e->getMessage());
        }
    }
