<?php

// A simple example which requests http://google.com/ through a SOCKS proxy.
// You can use any kind of proxy, for example https://github.com/leproxy/leproxy (defaults to localhost:8080) and execute it like this:
//
// $ php leproxy.php
//
// The proxy in this example defaults to 127.0.0.1:1080.
// To run the example, go to the project root and run:
//
// $ php examples/13-proxy-raw-https-protocol.php
//
// To run the same example with your proxy, the proxy URL can be given as an environment variable:
//
// $ socks_proxy=127.0.0.2:1080 php examples/13-proxy-raw-https-protocol.php
//
// 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.
