PHP 中的命名空间阻止使用 Yii 静态函数

问题描述

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

I just implemented namespaces in my small application as outlined here: http://www.yiiframework.com/doc/guide/1.1/en/basics.namespace

我遇到了一个问题，我的控制器将不再访问 Yii::app()->getRequest(); 说它找不到 include(C:UserskuhlhtdocsinstaLabelapplicationprotectedcomponentsYii.php):无法打开流:没有那个文件或目录.

I'm running into an issue where my controller will no longer access Yii::app()->getRequest(); saying it can't find include(C:UserskuhlhtdocsinstaLabelapplicationprotectedcomponentsYii.php): failed to open stream: No such file or directory.

我意识到这是因为我将命名空间声明为应用程序/组件.但我不知道如何解决这个问题...

I realize that's because I declared the namespace as application/components. But I'm not sure how to work around this one...

<?php

namespace applicationcomponents;

/**
 * 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();
    }

推荐答案

你需要完全限定相对类名Yii.

You need to fully qualify the relative class name Yii.

最方便的方法是导入类:只需在命名空间声明下方添加 use Yii;.

The most convenient way to do this is by importing the class: just add use Yii; below your namespace declaration.
