<?php

use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;

require __DIR__ . '/vendor/autoload.php';

$app = AppFactory::create();

// Sample in-memory data
$items = [];

$app->get('/items', function (Request $request, Response $response) use (&$items) {
    $response->getBody()->write(json_encode($items));
    return $response->withHeader('Content-Type', 'application/json');
});

$app->post('/items', function (Request $request, Response $response) use (&$items) {
    $data = json_decode($request->getBody(), true);
    $items[] = $data;
    $response->getBody()->write(json_encode($data));
    return $response->withHeader('Content-Type', 'application/json');
});

$app->run();

Demonstrates a simple Slim app with routes for listing and creating items, using minimal setup.
