ftp_nb_put() stores local_file on the FTP server, as remote_file. The transfer mode specified must be either FTP_ASCII or FTP_BINARY. The difference between this function and the ftp_put() is that this function uploads the file asynchronously, so your program can perform other operations while the file is being downloaded.
成功した場合に TRUE 、失敗した場合に FALSE を返します。
