# 使用命名空间（Working with Namespaces）[](# "永久链接至标题") [Namespaces](http://php.net/manual/en/language.namespaces.php) 可以用来避免类名的冲突，比如如果在一个应用中有两个控制器使用同样的名称，那么可以用namespace来区分他们。另外命名空间在创建组件或者模块的时候也是非常有用的。 ### 设置框架（Setting up the framework）[](# "永久链接至标题") 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; }); ~~~ ### 控制器加入命名空间（Controllers in Namespaces）[](# "永久链接至标题") 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() { } } ~~~ ### 模型加入命名空间（Models in Namespaces）[](# "永久链接至标题") 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](# "总目录") - [下一页](# "事件管理器（Events Manager）") | - [上一页](# "微应用（Micro Applications）") |
