11-proxy-raw-http-protocol.php

<?php

// A simple example which requests http://google.com/ through an SSH proxy server.
// The proxy can be given through the SSH_PROXY env and defaults to localhost otherwise.
//
// You can assign the SSH_PROXY environment and prefix this with a space to make
// sure your login credentials are not stored in your bash history like this:
//
// $  export SSH_PROXY=alice:password@example.com
// $ php examples/11-proxy-raw-http-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.
