Using FTP Functions

I've been looking at some of the PHP ftp functions and I had a couple of questions. 1) If you want to upload several files or a whole directory of files, would it be best to just put those uploads in a loop, or is there already some better recursive option that I'm not seeing. 2) Is there anyway to move a file from one directory on the ftp site to another directory? Would rename work for that? Does rename work to change directory names? (the manual just mentions files) Thanks, Paul P.S. Does anyone know of a unix program that can upload whole directory structures to an FTP server at a time? I don't see an option for it in the standard FTP program. Right now, I'm using scp -p -r to do it, but an FTP alternative would be great. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Paul Burney Webmaster and Internet Developer Educational Technology Unit Graduate School of Education and Information Studies University of California, Los Angeles (310) 825-8365 <webmaster@gseis.ucla.edu> <http://www.gseis.ucla.edu/> ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
