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 [, int resumepos])

ftp_nb_fget() retrieves remote_file from the FTP server, and writes it to the given file pointer, handle. The transfer mode specified must be either FTP_ASCII or FTP_BINARY. The difference between this function and the ftp_fget() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded.

Example 1. ftp_nb_fget() example

<?php

// open some file for reading
$file = 'index.php';
$fp = fopen($file, 'w');

$conn_id = ftp_connect($ftp_server);

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// Initate the download
$ret = ftp_nb_fget($conn_id, $fp, $file, FTP_BINARY);
while (
$ret == FTP_MOREDATA) {

   
// Do whatever you want
   
echo ".";

   
// Continue downloading...
   
$ret = ftp_nb_continue($conn_id);
}
if (
$ret != FTP_FINISHED) {
   echo
"There was an error downloading the file...";
   exit(
1);
}

// close filepointer
fclose($fp);
?>

Returns FTP_FAILED, FTP_FINISHED, or FTP_MOREDATA.
