php - 如何制作动态路由 PHP MVC

Question

如何为 /blog/* 创建路由，其中​​ * 是博客文章的 slug？

我正在从头开始制作一个 PHP MVC 框架，并且在视图中显示数据以及如何制作时遇到了麻烦，因此人们可以单击博客文章来查看它！

请查看 github：https ://github.com/fillemon10/cinemania-mvc了解并帮助我。我不知道如何处理从数据库检索数据到博客。

索引.php：

<?php

use app\controllers\AuthController;
use app\controllers\BlogController;
use app\controllers\SiteController;
use app\core\Application;
use app\models\Blog;

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

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

$config = [
    'userClass' => \app\models\User::class,
    'db' => [
        'dsn' => $_ENV['DB_DSN'],
        'user' => $_ENV['DB_USER'],
        'password' => $_ENV['DB_PASSWORD']
    ]
];

$app = new Application(dirname(__DIR__), $config);
$app->on(Application::EVENT_BEFORE_REQUEST, function () {
});

$app->router->get('/', [SiteController::class, 'home']);

$app->router->get('/contact', [SiteController::class, 'contact']);
$app->router->post('/contact', [SiteController::class, 'contact']);

$app->router->get('/login', [AuthController::class, 'login']);
$app->router->post('/login', [AuthController::class, 'login']);
$app->router->get('/register', [AuthController::class, 'register']);
$app->router->post('/register', [AuthController::class, 'register']);
$app->router->get('/logout', [AuthController::class, 'logout']);
$app->router->get('/myaccount', [AuthController::class, 'myaccount']);

$app->router->get('/blog', [BlogController::class, 'blog']);

$app->run();

路由器.php：

<?php

namespace app\core;

use app\core\exception\NotFoundException;

class Router
{
    public Request $request;
    public Response $response;
    protected array $routes = [];

    public function __construct(Request $request, Response $response)
    {
        $this->request = $request;
        $this->response = $response;
    }

    public function get($url, $callback, $params ="")
    {
        $this->routes['get'][$url] = $callback;
    }

    public function post($url, $callback)
    {
        $this->routes['post'][$url] = $callback;
    }

    public function resolve()
    {
        $url = $this->request->getUrl();
        $method = $this->request->method();
        $callback = $this->routes[$method][$url] ?? false;
        if ($callback === false) {
            throw new NotFoundException();
        }
        if (is_string($callback)) {
            return Application::$app->view->renderView($callback);
        }
        if (is_array($callback)) {
            /** @var \app\core\Controller $controller */
            $controller = new $callback[0]();
            Application::$app->controller = $controller;
            $controller->action = $callback[1];
            $callback[0] = $controller;
            foreach ($controller->getMiddlewares() as $middleware) {
                $middleware->execute();
            }
        }
        return call_user_func($callback, $this->request, $this->response);
    }
}
