create archive file in memory with zipArchive class

I want to generate credential zip file for user on the fly with
zipArchive and render it for download, so I created following code
---------------------------------------------------------
$zip =3D new ZipArchive();
$filename =3D '/tmp/xxx.zip';
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
     throw new Exception();
}
if($zip)
{
  =A0 $zip->addFromString('xxx.xx', $fileString);
}
$zip->close();
$fileString =3D file_get_contents($filename);
unlink($filename);

$this->getResponse()->setHeader('Content-Type', 'application/zip');
$this->getResponse()->setHeader('Content-Disposition','attac hment;filename=
=3Dxxx.zip');
$this->getResponse()->setBody($fileString);
-----------------------------------------------------
it works, but I think creating the file in memory is a better
approach, so I changed the 2nd lineI(using php 5.2.0) to
$filename =3D 'php://temp/xxx.zip';
then the php just won't archive the file and the file downloaded is
just a plain text file.

so
question 1, how to create zip Archive file in memory on the fly and
download it (I don't have to save it on disk)?
question 2, if there is no way to create in memory, is it safe to just
unlink() the file?

thanks in advance.

According to http://docs.php.net/manual/en/wrappers.php.php, it looks
like you should be using ...

$filename =3D 'php://temp';

That's it.

The actual file name is not your job.

It looks like this isn't possible.
