The ftp_nb_get() function downloads a file from the FTP server and saves it to a local file. (no blocking)
This function returns one of the following values:
FTP_FAILED (send/get failed)
FTP_FINISHED (send/get successful)
FTP_MOREDATA (send/get in progress)
Unlike ftp_get(), this function obtains the file asynchronously. This means your program can perform other operations while the file is downloading.
