As any middleware ->process() method, the callable receive implementations of Psr\Http\Message\ServerRequestInterface and Psr\Http\Server\RequestHandlerInterface as parameters and should return an implementation of Psr\Http\Message\ResponseInterface., _(*6)

<?php

namespace App;

use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;

use Ellipse\Middleware\CallableMiddleware;

// This middleware is wrapped around the given callable.
$middleware = new CallableMiddleware(function (ServerRequestInterface $request, RequestHandlerInterface $handler) {

    // ...

    return $handler->handle($request);

});

// The middleware ->process() method proxy the callable.
$response = $middleware->process($request, $handler);
