ZipArchive() (adding a directory)

Hello, group:

I'm able to successfully add files to a zip archive using php with the
following script, but I can't find anywhere I add directories, can
somebody help?


Thanks,

--TJ


<?php

$zip = new ZipArchive();
$filename = "./test112.zip";

if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}

$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test
string added as testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test
string added as testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
$zip->close();
?>
.
