PHP Extension

SSH Tunnel for Database Connection (such as ADO, ODBC, JDBC, etc.)

See more SSH Tunnel Examples

Demonstrates how to create an SSH tunneling client in a background thread of your application. This makes it possible to SSH tunnel database connections without the need for separate software (such as PuTTY) to be running. PHP Extension

<?php

include("chilkat.php");

$success = false;

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

// Connect to an SSH server and establish the SSH tunnel:
$success = $tunnel->Connect($sshHostname,$sshPort);
if ($success != true) {
    print $tunnel->lastErrorText() . "\n";

// Authenticate with the SSH server via a login/password
// or with a public key.  
// This example demonstrates SSH password authentication.

// The destination host/port is the database server.
// The DestHostname may be the domain name or 
// IP address (in dotted decimal notation) of the database
// server.

// Start accepting connections in a background thread.
// The SSH tunnels are autonomously run in a background
// thread.  There is one background thread for accepting
// connections, and another for managing the tunnel pool.

// At this point the app may connect to the database server through
// the SSH tunnel.  The database connection string would
// use "localhost" for the hostname and 3316 for the port.
// We're not going to show the database coding here,
// because it can vary depending on the API you're using
// (ADO, ODBC, OLE DB, etc. )

// This is where the application's database code would go...
