Stores a file from an open file to the FTP server (non-blocking)

&reftitle.description; `int` `ftp_nb_fput` `FTP\Connection` `ftp` `string` `remote_filename` `resource` `stream` `int` `mode` `FTP_BINARY` `int` `offset` 0

`ftp_nb_fput` uploads the data from a file pointer to a remote file on the FTP server.

The difference between this function and the `ftp_fput` is that this function uploads the file asynchronously, so your program can perform other operations while the file is being uploaded.

&reftitle.parameters;

`ftp`

- &ftp.parameter.ftp;

`remote_filename`

- The remote file path.

`stream`

- An open file pointer on the local file. Reading stops at end of file.

`mode`

- The transfer mode. Must be either `FTP_ASCII` or `FTP_BINARY`.

`offset`

- The position in the remote file to start uploading to.

&reftitle.returnvalues;

Returns `FTP_FAILED` or `FTP_FINISHED` or `FTP_MOREDATA`.

&reftitle.changelog;

&Version; | &Description;

       // Continue upload...
       $ret = ftp_nb_continue($ftp);
    }
    if ($ret != FTP_FINISHED) {
