The ftp_nb_get() function gets (downloads) a file from the FTP server, and saves it into a local file (non-blocking).
int ftp_nb_get ( resource $ftp_stream , string $local_file , string $remote_file [, int $mode = FTP_IMAGE [, int $resumepos = 0 ]] )
ftp_nb_get() retrieves a remote file from the FTP server, and saves it into a local file.
The difference between this function and ftp_get() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded
In the example above, newfile is 100 bytes smaller than README on the FTP server because we started reading at offset 100. If we didn't disable FTP_AUTOSEEK, the first 100 bytes of newfile would be '\0'.
