It seems this library hasn't been updated in a while. that's why I'm proposing a patch(patch1.diff). Also it seems in fput() function, the variable $rest is being used without being passed as parameter(patch2.diff).

In 43848:

FTP/PemFTP Library: Fix some PHP notices.

• ftp_base::glob() used each(), which is deprecated as of PHP 7.2.
• ftp_base::fget() was missing the decleration of its third parameter, $rest.

Props itowhid06.
See #44489.
