Namespaces in PHP preventing using of Yii static functions

Question

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

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

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 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();
    }

Answer 1

You need to fully qualify the relative class name Yii.

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

Answer 2

Have you tried:

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

\ will use the global namespace:

Prefixing a name with \ will specify that the name is required from the global space even in the context of the namespace.
