<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$ftp = new CkFtp2();

$ftp->put_Hostname('www.example-code.com');
$ftp->put_Username('example-code.com');
$ftp->put_Password('****');

$ftp->put_ProxyHostname('ftp.myproxyhost.com');
$ftp->put_ProxyPort(21);
// Note: Your FTP Proxy server may or may not require authentication.
$ftp->put_ProxyUsername('myProxyUsername');
$ftp->put_ProxyPassword('myProxyPassword');

// The ProxyMethod should be an integer value between 1 and 5.
// If you know your FTP proxy server's authentication scheme,
// you may set it directly.  To determine the ProxyMethod,
// call DetermineProxyMethod.  A return value of -1 indicates a failure.
// A return value of 0 indicates that nothing worked.
// A return value of 1-5 indicates the ProxyMethod that was 
// successful, and this should be the value used for the ProxyMethod
// property.

$pMethod = $ftp->DetermineProxyMethod();
print $pMethod . "\n";

$success = $ftp->Disconnect();
