Answer 1

PHP defaults to the active FTP mode. The active mode hardly ever works these days due to ubiquitous firewalls/NATs/proxies.

You almost always need to use the passive mode.

For that call the ftp_pasv after the ftp_login:

ftp_pasv($nyambungkeftp, true);

See my article on FTP connection modes, to understand, why you typically need to use the passive mode.
