Transfer a file from a website to a server

I want to transfer a few files from a we开发者_如何学Pythonbsite to a ftp server over the internet (bypassing my computer). Im guessing php is the best languaje to use, does anyone have any ideas?

Can you access the website server? If so, cpanel has a sweet built in transfer/backup utility that could send the whole directory to another server, including your ftp server.
