I don't believe there's a feature of the FTP protocol to check if a
file/folder exists.

Can you please provide a PHP userland solution to this, so that a
corresponding C implementation could be added.

I believe the way to go about it is list the CWD contents and check if that
exists and is of type DIR. You must also make sure that if a file exists
with the name of the directory you want to check it has to handle that
properly, it can't simply return true or false. If false then that means
you could create it because it doesn't exist. If true it means you can CD
into it and put stuff there, which is also not true.

Thanks,
Paul.
