01-http-request.php

<?php

// A simple example which uses an HTTP client to request https://example.com/ through an HTTP CONNECT proxy.
// You can use any kind of proxy, for example https://github.com/leproxy/leproxy and execute it like this:
//
// $ php leproxy.php
//
// The proxy defaults to localhost:8080.
// To run the example go to the project root and run:
//
// $ php examples/01-http-request.php
//
// To run the same example with your proxy, the proxy URL can be given as an environment variable:
//
// $ http_proxy=127.0.0.2:8080 php examples/01-http-request.php
