Using PHP to access FTP config

[Anon]

I have a website that, among other things, has an ftp server woven into it. Right now, access to the ftp server is pretty much unrestricted.

What I'd like to do, however, is try and find a way to access the ftp server (whether it be by config file manipulation or through a command line interface that the server supports) using php, so I might, for example, add an unique user account every time a member registers on the webpage.

A program like warftpd has a command line interface, but I have yet to figure out how to access is using ftp, whereas g6ftp has a users.ini file, but it doesn't reload until you restart the server.

Any ideas?

Thanks in advance-
