Hi,

I'm trying to create a zip file from some pdfs and have code similar to this

$id=$_GET['id'];
$fn = array("a", "b", "c", "d");
chdir('../downloads'); // the php file is in /php
$files = $fn[$id]."1.pdf ".$fn[$id]."2.pdf 7-17.pdf";
$command = "zip -9 " . $fn[$id] . ".zip " . $files;
header("content-type:application/zip");
header("Content-disposition: attachment; filename=" . $fn[$id] . ".zip");
header("Pragma: no-cache");
header("Expires: 0");
shell_exec($command);

The files do exist and a save as window appears, but the file generated is 0
bytes long. I have tried changing the command to "/usr/bin/zip"
and "//usr//bin//zip" and putting the shell_exec before the header lines as
well changing shell_exec to exec and even just system. All the same result.

Is there something I'm missing here?

TTFN

Paul
