Components of yii

When we create a module, the corresponding path alias has been created.
For example, we have defined a module: www

12345

‘modules‘=>array(    ‘www‘=>array(        ‘class‘=>‘applications.modules.www.WwwModule‘,    ),),

Print:
Echo yii: APP ()-> getpathofalias ('www ')
You will find that the WWW alias has been directed to our www module.

Assume that the following directory is available in our www module:
WWW
-Components
-- Apibase. php
-Extensions
-Vendors
-- Curl. php

How can I load the components or other third-party packages?
As follows:

123456789

‘modules‘=>array(    ‘www‘=>array(        ‘class‘=>‘applications.modules.www.WwwModule‘,        ‘components‘ => array(             ‘api‘=>array(‘class‘=>‘www.components.ApiBase‘),             ‘curl‘=>array(‘class‘=>‘www.vendors.Curl‘),        ),    ),),

So how can I get it in the controller:
As follows:

12	$api = $this->getModule()->api;$curl = $this->getModule()->curl;

$ This is the current controller.

Note: yii: APP ()-> curl is not used to obtain component, because we define component into modules.
What if other modules want to use our extensions?

1	$curl = Yii::app()->getModule(‘www‘)->curl;

Of course, for public extensions, it is not recommended to define a single module or put it in the external components. Then you can use yii: APP ()-> curl to get it.
