(PHP Extension) REST through SSH Tunnel

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls.

// 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.
