if you examine the first user submitted function, ftp_putAll, it will work only if you extract this line and its matching bracket.
if (!@ftp_chdir($conn_id, $dst_dir."/".$file))
The function will have changed into that directory before having uploaded files to it. This alters your upload path and the system will try to upload into an essentially non-existent directory (duped at the end).
Hope this helps some of you.
Cheers.
