It Worked For Me. It Download My .Zip File. But, you have to provide the full path of File, where it is located.
For ex: My File is inside assets/upload Folder. Attach name of that file with this location. You will download it without any problem.

$FilePaths='assets/Upload/'.$FileName; //Give proper file path with file name.

download_file($FilePaths);

function download_file( $fullPath )
{
  if( headers_sent() )
    die('Headers Sent');


  if(ini_get('zlib.output_compression'))
    ini_set('zlib.output_compression', 'Off');


  if( file_exists($fullPath) )
  {

    $fsize = filesize($fullPath);
    $path_parts = pathinfo($fullPath);
    $ext = strtolower($path_parts["extension"]);

    switch ($ext) 
    {
      case "pdf": $ctype="application/pdf"; break;
      case "exe": $ctype="application/octet-stream"; break;
      case "zip": $ctype="application/zip"; break;
      case "doc": $ctype="application/msword"; break;
      case "xls": $ctype="application/vnd.ms-excel"; break;
      case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
      case "gif": $ctype="image/gif"; break;
      case "png": $ctype="image/png"; break;
      case "jpeg":
      case "jpg": $ctype="image/jpg"; break;
      default: $ctype="application/force-download";
    }

    header("Pragma: public"); 
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Cache-Control: private",false); 
    header("Content-Type: $ctype");
    header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: ".$fsize);
    ob_clean();
    flush();
    readfile( $fullPath );

  } 
  else
    die('File Not Found');

}
