So I am copying the files to a temp dir, and then zip em up, delete them
afterwards. I copy them to the dir so I wouldn't have the whole
/kfz_images/number/full/ structure in the zip).
Aaaanyhow, it works, it does work fast enough, and I am happy :o)
Thanks a bunch, guys, and have a great day!

http://pear.php.net/package/Archive_Zip and/or
http://pear.php.net/package/File_Archive
and please create a *new* message instead of replying to an existing one
and changing the topic. It screws up message threading (in email clients
and in the archives).
Not in gmail :)
I had same problem lately, wanted also to create zip files from PHP, i
tried various build in functions, but i ended up with the exec way.
It has been said before, but PHP probably doesn't have the right
permissions to write the .zip file, so i would recommend you to write
to /tmp first.

Here's a link to the zip class that I use
http://www.phpclasses.org/browse/package/945.html
One thing though, your PHP install has to be compiled with "--with-zlib"
That was the only thing that I ran into with this.
Since you are creating files to download, with this class, you don't even need to write them to the
filesystem. You just create the archive in memory (given that you have enough RAM && php is allowed
to consume as much memory as it would take the create the archive) and then dump it to the browser
instead of using readfile(). You save the time/space/headaches of trying to write your zip file to
the filesystem.
