<?php
// Simple plaintext HTTP and secure HTTPS client example (for illustration purposes only).
// This shows how an URI parameter can parsed to decide whether to establish
// a plaintext TCP/IP or secure TLS connection and then send an
// application level protocol message (HTTP).
// Real applications should use react/http-client instead!
//
// Unlike examples #11 and #12, this example will actually take an optional URI
// parameter and parse it to connect to the correct default port and use the
// correct transport protocol.
