# 使用命名空間（Working with Namespaces）[](# "永久鏈接至標題") [Namespaces](http://php.net/manual/en/language.namespaces.php) 可以用來避免類名的沖突，比如如果在一個應用中有兩個控制器使用同樣的名稱，那么可以用namespace來區分他們。另外命名空間在創建組件或者模塊的時候也是非常有用的。 ### 設置框架（Setting up the framework）[](# "永久鏈接至標題") Using namespaces has some implications when loading the appropriate controller. To adjust the framework behavior to namespaces is necessaryto perform one or all of the following tasks: Use an autoload strategy that takes into account the namespaces, for example with Phalcon\Loader: ~~~ <?php $loader->registerNamespaces( array( "Store\\Admin\\Controllers" => "../bundles/admin/controllers/", "Store\\Admin\\Models" => "../bundles/admin/models/" ) ); ~~~ Specify it in the routes as a separate parameter in the route's paths: ~~~ <?php $router->add( "/admin/users/my-profile", array( "namespace" => "Store\\Admin", "controller" => "Users", "action" => "profile" ) ); ~~~ Passing it as part of the route: ~~~ <?php $router->add( "/:namespace/admin/users/my-profile", array( "namespace" => 1, "controller" => "Users", "action" => "profile" ) ); ~~~ If you are only working with the same namespace for every controller in your application, then you can define a default namespacein the Dispatcher, by doing this, you don't need to specify a full class name in the router path: ~~~ <?php use Phalcon\Mvc\Dispatcher; // Registering a dispatcher $di->set('dispatcher', function () { $dispatcher = new Dispatcher(); $dispatcher->setDefaultNamespace("Store\\Admin\\Controllers"); return $dispatcher; }); ~~~ ### 控制器加入命名空間（Controllers in Namespaces）[](# "永久鏈接至標題") The following example shows how to implement a controller that use namespaces: ~~~ <?php namespace Store\Admin\Controllers; use Phalcon\Mvc\Controller; class UsersController extends Controller { public function indexAction() { } public function profileAction() { } } ~~~ ### 模型加入命名空間（Models in Namespaces）[](# "永久鏈接至標題") Take the following into consideration when using models in namespaces: ~~~ <?php namespace Store\Models; use Phalcon\Mvc\Model; class Robots extends Model { } ~~~ If models have relationships they must include the namespace too: ~~~ <?php namespace Store\Models; use Phalcon\Mvc\Model; class Robots extends Model { public function initialize() { $this->hasMany( "id", "Store\\Models\\Parts", "robots_id", array( "alias" => "parts" ) ); } } ~~~ In PHQL you must write the statements including namespaces: ~~~ <?php $phql = 'SELECT r.* FROM Store\Models\Robots r JOIN Store\Models\Parts p'; ~~~ | - [索引](# "總目錄") - [下一頁](# "事件管理器（Events Manager）") | - [上一頁](# "微應用（Micro Applications）") |
