script wrappers and php file downloads

Okay, here's the deal, I've scoured the web and nobody can provide an answer that works! I want users to be able to download a PHP file from my site. It runs through a wrapper, so people can't see the path, ie

mysite.com/download.php?var=file.php

Here's the best I've found.

--start snippet--

OK. I'm halfway there. I'm using the following wrapper:

header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=$filename");

This works fine in Netscape with the correct filename showing up. MSIE pops up the window with the filename of the wrapper instead of the $var variable.

Any other way to "force" the filename or at least another way to do it that will work in MSIE?

I think MSIE is the one where you add $var to the end of the URL, no matter how goofy it looks, to convince it what to name it. I think there's also a Microsoft non-standard header for the name of the file, but I always forget what it is... It's in the mailing list archives.

EG:

http://vectox.com/download.php/filename.zip?var=filename.zip


That middle filename.zip is, of course, totally bogus as a pathname and not used by PHP at all, but MSIE sees it at the end of the "path" and says,
"Oh, this file should be named filename.zip".

--end snippet --

So I built a browser detect that writes the path EXACTLY as it has above, but guess what? It don't be to work! I have tried a lot of methods but IE still calls the file
"download" as in download.php, the name of the wrapper. Help is MUCH appreciated, alternate solutions also kindly accepted!

Here's a link to a script posted on the forums at phpbuilder...check it out and let me know if it works...
