# ftp_nb_put

(PHP 4 >= 4.3.0, PHP 5)

ftp_nb_put -- Stores a file on the FTP server (non-blocking)

## Description

int ftp_nb_put ( resource ftp_stream, string remote_file, string local_file, int mode [, int startpos])

ftp_nb_put() stores local_file on the FTP server, as remote_file. The transfer mode specified must be either `FTP_ASCII` or `FTP_BINARY`. The difference between this function and the ftp_put() is that this function uploads the file asynchronously, so your program can perform other operations while the file is being uploaded.

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

示範 1.ftp_nb_put() example

`<?php // Initiate the Upload $ret = ftp_nb_put($my_connection, "test.remote", "test.local", FTP_BINARY); while ($ret == FTP_MOREDATA) { // Do whatever you want echo "."; // Continue uploading... $ret = ftp_nb_continue($my_connection); } if ($ret != FTP_FINISHED) { echo "There was an error uploading the file..."; exit(1); } ?>`

示範 2.Resuming an upload with ftp_nb_put()

`<?php
// Initiate
$ret = ftp_nb_put($my_connection, "test.remote", "test.local",
FTP_BINARY, ftp_size("test.remote"));
// OR: $ret = ftp_nb_put($my_connection, "test.remote", "test.local",
// FTP_BINARY, FTP_AUTORESUME);
while ($ret == FTP_MOREDATA) {
// Do whatever you want
echo ".";
// Continue uploading...
$ret = ftp_nb_continue($my_connection);
}
if ($ret != FTP_FINISHED) {
echo "There was an error uploading the file...";
exit(1);
}
?>`
