php - PHP 中的命名空间阻止使用 Yii 静态函数

Question

我刚刚在我的小应用程序中实现了 namespace ，如下所述:http://www.yiiframework.com/doc/guide/1.1/en/basics.namespace

我遇到了一个问题，我的 Controller 将不再访问 Yii::app()->getRequest(); 说它找不到 include(C:\Users\bkuhl\htdocs\instaLabel\application\protected\components\Yii.php): 无法打开流:没有这样的文件或目录。

我意识到那是因为我将命名空间声明为应用程序/组件。但我不确定如何解决这个问题......

<?php

namespace application\components;

/**
 * Controller is the customized base controller class.
 * All controller classes for this application should extend from this base class.
 */
class Controller extends \CController {
    /* @var $request CHttpRequest */
    protected $request = null;

    /**
     * @var string the default layout for the controller view. Defaults to '//layouts/column1',
     * meaning using a single column layout. See 'protected/views/layouts/column1.php'.
     */
    public $layout='//layouts/column1';
    /**
     * @var array context menu items. This property will be assigned to {@link CMenu::items}.
     */
    public $menu=array();
    /**
     * @var array the breadcrumbs of the current page. The value of this property will
     * be assigned to {@link CBreadcrumbs::links}. Please refer to {@link CBreadcrumbs::links}
     * for more details on how to specify this property.
     */
    public $breadcrumbs=array();

    public function __construct ($id, $module = null) {
        parent::__construct($id, $module);

        $this->request = Yii::app()->getRequest();
    }

你需要完全限定相关类名Yii。

最方便的方法是通过 importing类:只需在命名空间声明下方添加 use Yii;。
