FTP info in a variable

I have to write a little program that pulls information from a database, formats it into csv format for importing into excel and ftps it to another server. I have everything worked out except for the ftping. I have read through http://us4.php.net/manual/en/ref.ftp.php and I know I can get the data from the database, save it to a file and ftp it. Does anybody know if I can skip the step of saving it to a file and ftp/stream it directly to a filename on another server? Thanks Steve
