Demonstrates how to connect to an FTP server, examine the server's SSL/TLS certificate, and then, if it meets the application's security requirements, proceed to authenticate. Chilkat2 PHP

<?php

use Chilkat2\Cert;
use Chilkat2\Ftp2;

// This example assumes Chilkat Ftp2 to have been previously unlocked.
// See Unlock Ftp2 for sample code.

$ftp = new Ftp2();

$ftp->Hostname = 'www.authtls-ftps-server.com';
$ftp->Username = 'FTP_LOGIN';
$ftp->Password = 'FTP_PASSWORD';
$ftp->AuthTls = true;
$ftp->Port = 21;

// Connect to the FTP server using explicit TLS (AUTH TLS).
try {
    $ftp->ConnectOnly();

    // Get the FTP server's certificate.
    $serverCert = new Cert();
    $ftp->GetServerCert($serverCert);

    // Now that we have the certificate, we can check it in any way we desire.
    // (See the online reference documentation for the certificate object's methods
    // and properties)...

    // Assuming the certificate is OK, proceed to authenticate with the FTP server.
    $ftp->LoginAfterConnectOnly();

    echo $e->getMessage(), "\n";
    exit;

// Proceed with uploading/download files, etc...

$ftp->Disconnect();
