<?php

// A simple example which requests https://www.google.com/ through a SOCKS proxy with local DNS resolution.
// The proxy can be given as first argument and defaults to 127.0.0.1:1080 otherwise.
//
// Not already running a SOCKS proxy server? See also example #21 or try this:
// $ ssh -D 1080 localhost
//
// For illustration purposes only. If you want to send HTTP requests in a real
// world project, take a look at example #01, example #02 and https://github.com/reactphp/http#client-usage.
