(PHP ActiveX) SCP Upload Contents of String to Remote File

Demonstrates how to upload the contents of a string variable using the SCP protocol (Secure Copy Protocol over SSH). The text is uploaded to a file in specific remote directory. If the file did not already exist, it is created. If it already existed, it is overwritten.

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Ssh')
$ssh = new COM("Chilkat.Ssh");

// Connect to an SSH server:

// Hostname may be an IP address or hostname:
$hostname = 'www.some-ssh-server.com';
$port = 22;

if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;

// Wait a max of 5 seconds when reading responses..

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

// Once the SSH object is connected and authenticated, we use it
// as the underlying transport in our SCP object.
