# ftp_nb_fput

(PHP 4 >= 4.3.0, PHP 5)

ftp_nb_fput -- Stores a file from an open file to the FTP server (non-blocking)

## Description

int ftp_nb_fput ( resource ftp_stream, string remote_file, resource handle, int mode [, int startpos])

ftp_nb_fput() uploads the data from the file pointer handle until it reaches the end of the file. The results are stored in remote_file on the FTP server. The transfer mode specified must be either `FTP_ASCII` or `FTP_BINARY`. The difference between this function and the ftp_fput() is that this function uploads the file asynchronously, so your program can perform other operations while the file is being uploaded.

`<?php $file = 'index.php'; $fp = fopen($file, 'r'); $conn_id = ftp_connect($ftp_server); $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // Initate the upload $ret = ftp_nb_fput($conn_id, $file, $fp, FTP_BINARY); while ($ret == FTP_MOREDATA) { // Do whatever you want echo "."; // Continue upload... $ret = ftp_nb_continue($conn_id); } if ($ret != FTP_FINISHED) { echo "There was an error uploading the file..."; exit(1); } fclose($fp); ?>`

Returns `FTP_FAILED`, `FTP_FINISHED`, or `FTP_MOREDATA`.
