<?php

// A simple example which requests https://google.com/ either directly or through
// an HTTP CONNECT proxy.
// The Proxy can be given as first argument or does not use a proxy otherwise.
// This example highlights how changing from direct connection to using a proxy
// actually adds very little complexity and does not mess with your actual
// network protocol otherwise.
