PHP Script to transfer files from one ftp to another ftp

Question

I want run a php script on a server where are no files to transfer. This script should transfer files from one ftp (with password) to another ftp (with password). It is possible in php? ftp_fput allows only to transfer a local file to a ftp-server? Is it right?

I suggest you to use thephpleague's Flysystem FTP adapter. You can create a script based on this package and use it on your control server in order to transfer files from ftp server A to ftp server B.

Here is an example script that transfer data from server A to server B using sftp. NOTE: The following script assumes you have installed the flysystem package (e.g. composer require league/flysystem).

<?php

require_once __DIR__ . '/vendor/autoload.php';

use League\Flysystem\Filesystem;
use League\Flysystem\Sftp\SftpAdapter;

$source = new Filesystem(new SftpAdapter([
    'host' => 'server A',
    'port' => 'server A port',
    'username' => 'server A sftp user',
    'password' => 'server A sftp pwd',
    'root' => 'source folder on server A',
    'timeout' => 10,
]));

$destination = new Filesystem(new SftpAdapter([
    'host' => 'server B',
    'port' => 'server B port',
    'username' => 'server B sftp user',
    'password' => 'server B sftp pwd',
    'root' => 'destination folder on server B',
    'timeout' => 10,
]));

$files = $source->listContents();

foreach ($files as $file) {
    $data = $source->read($file['path']);
    $destination->put($file['path'], $data);
}

It establishes a connection to the source ($source) and the destination ($destination) servers. List the contents on the source (listContents() method) and in a foreach loop it reads the files (read()) and put their content (put()) to the desired place one by one.
