<?php

// Simple plaintext HTTP client example (for illustration purposes only).
// This shows how a plaintext TCP/IP connection is established to then send an
// application level protocol message (HTTP).
// Real applications should use react/http-client instead!
//
// This simple example only accepts an optional host parameter to send the
// request to. See also example #22 for proper URI parsing.
