<?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 assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$sftp = new CkSFtp();

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to connecting:
// The SOCKS hostname may be a domain name or 
// IP address:
$sftp->put_SocksHostname('www.mysocksproxyserver.com');
$sftp->put_SocksPort(1080);
$sftp->put_SocksUsername('myProxyLogin');
$sftp->put_SocksPassword('myProxyPassword');

// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$sftp->put_SocksVersion(5);

// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
$hostname = 'sftp.example.com';
$port = 22;
$success = $sftp->Connect($hostname,$port);
if ($success != true) {
    print $sftp->lastErrorText() . "\n";
    exit;
}

// Your application is now connected to an SFTP/SSH server 
// through a SOCKS4 or SOCKS5 proxy.
