Multiple file uploads (ftp)

Hi all, I've been playing with the php ftp functions for a little while. I was wondering if there was anyway to upload multiple files. I was thinking that perhaps there was a way to get the user to select a directory and load the files in a listbox and then allow the user to select multiple files and submit them. I've yet to test this (I'm still playing with getting *one* file uploaded :-)), but is there anyway to get multiple files to be uploaded via a browser? Thanks James
