Example

<?php

use WellRESTed\Message\Stream;
use WellRESTed\Server;

require_once "vendor/autoload.php";

// Build some middleware. We'll register these with a server below.
// We're using callables to fit this all in one example, but these
// could also be classes implementing WellRESTed\MiddlewareInterface.

// Set the status code and provide the greeting as the response body.
$hello = function ($request, $response, $next) {

    // Check for a "name" attribute which may have been provided as a
    // path variable. Use "world" as a default.
    $name = $request->getAttribute("name", "world");

    // Set the response body to the greeting and the status code to 200 OK.
    $response = $response->withStatus(200)
        ->withHeader("Content-type", "text/plain")
        ->withBody(new Stream("Hello, $name!"));

    // Propagate to the next middleware, if any, and return the response.
    return $next($request, $response);

};

// Add a header to the response.
$headerAdder = function ($request, $response, $next) {
    // Add the header.
    $response = $response->withHeader("X-example", "hello world");
    // Propagate to the next middleware, if any, and return the response.
    return $next($request, $response);
};

// Create a server
$server = new Server();

// Start each request-response cycle by dispatching the header adder.
$server->add($headerAdder);

// The header adder will propagate to this router, which will dispatch the
// $hello middleware, possibly with a {name} variable.
$server->add($server->createRouter()
    ->register("GET", "/hello", $hello)
    ->register("GET", "/hello/{name}", $hello)
);

// Read the request from the client, dispatch middleware, and output.
$server->respond();
