##1.在组件内部创建依赖对象 首先，我们假设，我们要开发一个组件命名为SomeComponent。 这个组件中依赖一个数据库连接。 组件 依赖 数据库连接对象，我们在组件中创建数据库连接对象 ###demo1: class SomeComponent { /** * The instantiation of the connection is hardcoded inside * the component so is difficult to replace it externally * or change its behavior */ public function someDbTask() { $connection = new Connection(array( "host" => "localhost", "username" => "root", "password" => "secret", "dbname" => "invo" )); // ... } } $some = new SomeComponent(); $some->someDbTask(); 在这个例子中，数据库连接在component中被创建，这种方法是不切实际的，这样做的话，我们将不能改变数据库连接参数及数据库类型等一些参数。而且耦合性太高了。 #2.改进： 把依赖对象注入组件中

I have previously used reactJS on another project. When building said project i noticed a downfall namely the loss of SEO benefit associated with JS rendered components. I am rebuilding an old project and I would like to replace some of the Javascript with ReactJS. For example, a multi step form - I'd like to replace it with a stateful component that displays the correct stage as required.

To achieve this my research implies that I should be using React's React.renderComponentToString Having

I am experiencing a very strange issue with Phalcon. Whenever I use Response inside a controller the framework becomes very slow. Here is my simple controller: <?php // file: app/controllers/TestController.php use Phalcon\Mvc\View; class TestController extends ControllerBase { private $response; public function initialize() { $this->view->setRenderLevel(View::LEVEL_NO_RENDER); $this->response = new Phalcon\Http\Response(); $this->response->setStatusCode(200, "OK"); } public function indexAction() { $this->response->setContent("phalcon")->send(); // very slow } } Whenever I use new Phalcon\Http

I'm looking for a way to modify a request URL before it gets dispatched. For instance, the following URLs should be handled by the same controller/action: /en/paris /de/paris /paris I would like to capture the country code if it is present, then rewrite the URL without it so that controllers don't have to deal with it. I tried the 'dispatch:beforeDispatchLoop' event but it doesn't seam to be designed for that. Any idea? If you can convention that all country code comes first in the path, perhaps an additional rewrite rule can help you: <IfModule mod_rewrite.c> RewriteCond %{REQUEST_FILENAME} !
