ftp_nb_fget
Retrieves a file from the FTP server and writes it to an open file (non-blocking)
Description
int ftp_nb_fget(
FTP\Connection $ftp,
resource $stream,
string $remote_filename,
int $mode = FTP_BINARY,
int $offset = 0
)
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.

An open file pointer in which we store the data.
-
remote_filename

FTP_BINARY.

<?php

$file = 'index.php';
$fp = fopen($file, 'w');
$ftp = ftp_connect($ftp_server);
$login_result = ftp_login($ftp, $ftp_user_name, $ftp_user_pass);
// Initiate the download
$ret = ftp_nb_fget($ftp, $fp, $file, FTP_BINARY);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
