Hi All,
Im Having the following code to creare zip file and download

//function to zip and force download the files using PHP
function zipFilesAndDownload($file_names,$archive_file_name,$file_path)
{
  //create the object
  $zip = new ZipArchive();
  //create the file and throw the error if unsuccessful
  if ($zip->open($archive_file_name, ZIPARCHIVE::CREATE )!==TRUE) {
    exit("cannot open <$archive_file_name>\
");
  }

  //add each files of $file_name array to archive
  foreach($file_names as $files)
  {
    $zip->addFile($file_path.$files,$files);
  }
  $zip->close();

  //then send the headers to foce download the zip file
  header("Content-type: application/zip");
  header("Content-Disposition: attachment; filename=$archive_file_name");
  header("Pragma: no-cache");
  header("Expires: 0");
  readfile("$archive_file_name");
  exit;
}

  $file_names=array('test.php','test1.txt');
  $archive_file_name='zipped.zip';
  $file_path=dirname(__FILE__).'/';
  zipFilesAndDownload($file_names,$archive_file_name,$file_path);

Here i have to rectify 2 problems
1.Download code should ask save location
2.One more copy is created in source location.If i upload this code into server, My server will be overloaded.

How to resolve this? Plz help

I don’t get this one.
Download code should ask whom for what save location?

Do something like


if (!file_exists($archive_file_name))
{
       // create ZIP file
}
// send headers and send the file using readfile()
