FTP_NB_FGET(3) 1 FTP_NB_FGET(3)
ftp_nb_fget - Retrieves a file from the FTP server and writes it to an open file (non-blocking)
SYNOPSIS
int ftp_nb_fget (resource $ftp_stream, resource $handle, string $remote_file, int $mode, [int $resumepos])
DESCRIPTION
ftp_nb_fget(3) retrieves a remote file from the FTP server.
The difference between this function and ftp_fget(3) is that this function retrieves the file asynchronously, so your program can perform
other operations while the file is being downloaded.

- The link identifier of the FTP connection.
o $handle
- An open file pointer in which we store the data.
o $remote_file
- The remote file path.
o $mode
