            $path =$file_path[0]->folder_path ;
            $finallink = ($_SERVER['DOCUMENT_ROOT'] . "/cobacfms/" . $path);
            $this->zip->read_dir(($finallink), false);
            $this->zip->download(date('m-d-Y'));
    }catch(Exception $e){
        echo 'Caught exception: ',  $e->getMessage(), "\n";
    }



        }

This is the solution to my problem

Your zip file creation is having issue.

I would suggest you to first check you content availability and then create zip file and at last download it.

To create ZIP file

$sourcePath = 'uploads/sourceDirectory';
$targetPath = 'uploads/destDirectory';    
if (file_exists($sourcePath)){
        if(!copy($sourcePath, $targetPath)){ //Copy file source to destination directory
              return ['status' => false, 'msg' => 'File missing'];  
          }
}

if (file_exists($targetPath)){ // check target directory
       $this->zip->read_dir($targetPath,False); // read target directory
       if(!$this->zip->archive($targetPath.'.zip')){ // zip target directory
            return ['status' => false, 'msg' => 'Zip file creation Failed!'];
       }else{
            return ['status' => false, 'msg' => 'Zip file Created'];
       }
}
