Eagle框架实现了依赖注入容器（Dependency Injection Container）、路由（route）等组件,其它如ORM、cache、validation、filesystem等组件可以使用composer来由用户自由扩展。
composer require parvin/eagle-framework
PHP7以上
route可以使用symfony的http foundation组件来处理HTTP消息请求（http messages）。
<?php
require 'vendor/autoload.php';
use Eagle\Route\Router;
use Symfony\Component\HttpFoundation\Request;
$router = new Router();
$router->get('/articles', function () {
return 'This is articles list';
});
$router->get('/articles/{id:\d+}', function ($id) {
return 'Article id: ' . $id;
});
/* title 为可选参数 */
$router->get('/articles/{id:\d+}[/{title}]', function ($id, $title) {
return 'Article id: ' . $id . ', title: ' . $title;
});
/*匹配处理路由组*/
$router->group('/articles', function () use ($router) {
$router->get('/list', function() {
return 'This is articles list';
});
$router->get('/detail', function ($id, $title) {
return 'Article detail id: ' . $id . ', title: ' . $title;
});
});
$request = new Request();
$routeHandler = $router->getRouteHandler();
$response = $routeHandler->handle($request);
echo $response;Dependency injection Container基于PSR-11规范实现，包括3种注入实现方式：构造方法注入（Constructor Injection）、setter类方法或属性注入（Setter Injection）、匿名回调函数注入（ Closure callable Injection ）。
