How can PHP be used to transfer images and text files from one server to another while maintaining data privacy and security?

To transfer images and text files from one server to another while maintaining data privacy and security, you can use PHP to securely upload the files to the destination server using secure protocols like SFTP or HTTPS. You can also encrypt the files before transferring them to ensure data privacy. 

<?php

// Set up connection details for the destination server
$ftp_server = 'destination_server.com';
$ftp_username = 'username';
$ftp_password = 'password';

// Connect to the destination server using SFTP
$connection = ssh2_connect($ftp_server, 22);
ssh2_auth_password($connection, $ftp_username, $ftp_password);

// Upload file securely
$local_file = 'local_file.jpg';
$remote_file = 'remote_file.jpg';
ssh2_scp_send($connection, $local_file, $remote_file, 0644);

// Close the connection
ssh2_exec($connection, 'exit');

?>
