Are there alternative methods, such as FTP upload, that are more secure for uploading multiple files in PHP?

When uploading multiple files in PHP, using FTP upload can be a more secure alternative compared to the traditional file upload method. FTP upload allows for more control over the upload process and can provide additional security measures such as encryption and authentication. By utilizing FTP upload, you can ensure that your files are securely transferred to the server without exposing them to potential vulnerabilities. 

// Example FTP upload code snippet

$ftp_server = 'ftp.example.com';
$ftp_username = 'username';
$ftp_password = 'password';
$local_files = ['file1.txt', 'file2.txt'];
$remote_directory = '/uploads/';

$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);

if ($conn_id && $login_result) {
    foreach ($local_files as $local_file) {
        $remote_file = $remote_directory . basename($local_file);
        if (ftp_put($conn_id, $remote_file, $local_file, FTP_BINARY)) {
            echo "Successfully uploaded $local_file to $ftp_server\n";
        } else {
            echo "Error uploading $local_file\n";
        }
    }

    ftp_close($conn_id);
} else {
    echo "FTP connection failed\n";
}
