(PHP ActiveX) Multiple Hop SSH to SFTP

Demonstrates how to SFTP through an intermediate SSH server (multiple hop). The scheme looks like this:

Application => ServerSSH1 => ServerSFtp

The ConnectThroughSsh method is added in Chilkat version 9.5.0.55 to accomplish this task.

<?php

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

$ssh1 = new COM("Chilkat_9_5_0.Ssh");

// Hostname may be an IP address or domain name:
$hostname = '192.168.1.111';
$port = 22;

// Connect directly to the 1st SSH server:
$success = $ssh1->Connect($hostname,$port);
if ($success != 1) {
    print $ssh1->LastErrorText . "\n";
    exit;
}

// Authenticate using login/password:
$success = $ssh1->AuthenticatePw('myLogin','myPassword');
if ($success != 1) {
    print $ssh1->LastErrorText . "\n";
    exit;
}

// Connect through the 1st SSH connection to reach a 2nd SSH server (for SFTP)
// Note: Any number of connections may be simultaneously tunneled through a single
// existing SSH connection.
$sftp = new COM("Chilkat_9_5_0.SFtp");

// Connect to some SSH/SFTP server through ssh1.
$success = $sftp->ConnectThroughSsh($ssh1,'sftp.someremoteserver.com',22);
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Authenticate with the SFTP server. 
$success = $sftp->AuthenticatePw('myLogin','myPassword');
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// After authenticating, the SFTP subsystem must be initialized:
$success = $sftp->InitializeSftp();
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Upload from the local file to the SSH server.
// Important -- the remote filepath is the 1st argument,
// the local filepath is the 2nd argument;
$remoteFilePath = 'hamlet.xml';
$localFilePath = 'c:/temp/hamlet.xml';

$success = $sftp->UploadFileByName($remoteFilePath,$localFilePath);
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

print 'Success.' . "\n";

// Close the connection with the SFTP server.(This closes the the tunnel through ssh1.)
// The connection with ssh1 is still alive, and may be used for more connections.
$sftp->Disconnect();

// ...
// ...
// ...

$ssh1->Disconnect();
