how do you upload to a 3rd-party remote server?

Hi All I am working on a page which will write out a file (using another server-side language) and then that file will get uploaded nightly to someone else's FTP directory, on a 3rd party remote server. As I start to contemplate that last part about auto-uploading to someone else's FTP directory it escapes me what that code will need to look like.. I have some ideas, but I thought to just ask you first.

Can someone outline that pseudo code in PHP for me?    .. so I can translate it to the language I am working with?

Or is this a shell operation? (where I am even more green.) ------------ Govinda govinda.webdnatalk@gmail.com
