ftp_nb_fget
(PHP 4 >= 4.3.0, PHP 5)
ftp_nb_fget — Retrieves a file from the FTP server and writes it to an open file (non-blocking)
Description
int ftp_nb_fget
( resource $ftp_stream
, resource $handle
, string $remote_file
, int $mode

The difference between this function and ftp_fget() is
that this function retrieves the file asynchronously, so your program can
perform other operations while the file is being downloaded.
