What are the predefined components of Yii framework?

To use PHP's Yii framework, you need to configure a very important file: main.php. To configure a component, you need to specify the class name of the component through the 'class' field, but some do not need to be specified because they are predefined components of the Yii framework, such as the 'db' component.

So, do you know which components are predefined by Yii and where are they predefined?

First, in the CApplication.php file (https://github.com/yiisoft/yii/blob/1.1.16/framework/base/CApplication.php), the following is predefined Components:

''YII_PATH''array('' ''',

$components=array(

'coreMessages' =>array(

'class'=> 'language'=>

en_us

, 'basePath'=>

.

DIRECTORY_SEPARATOR.'messages ', ),

db

=>

'class'=>

messages' => ,),

'errorHandler

=>

array( 'class

=>

'CErrorHandler', ),

'securityManager

=>

array( 'class

=>

'statePersister '=> sister',

),

'urlManager'=>array(

'class'=> ;'CUrlManager',

),

'request '=>array(

'class'=>'CHttpRequest',

),

'format'=> 'CFormatter'

),);

Then in the CWebApplication.php file (https://github.com/yiisoft/yii/blob/1.1.16/framework/web/CWebApplication.php), the following components are predefined :

'=>( array(class=>CClientScriptwidgetFactory'=> =>

'Session'=>array(
	'class'=> 'CHttpSession',
	),
	' assetManager'=>array(
	'class'=> ),
	user'
array	'CWebUser', (
	'class' => 'authManager'=>
'	'=>'CPhpAuthManager',
	), 'clientScript'=>
'	' ,
	), '
	array(' class'
The above introduces what are the predefined components of Yii framework? , including Session, Application, and github content. I hope it will be helpful to friends who are interested in PHP tutorials.
