Ⅰ. Basic concepts
1. Entry file
Entry file content: The general format is as follows:

$yii=dirname(__FILE__).'/../../framework/yii.php';/ /Yii framework location
$config=dirname(__FILE__).'/protected/config/main.php';//The main configuration file location of the current application

// When deploying the formal environment, remove the following line
// defined('YII_DEBUG') or define('YII_DEBUG',true);//Whether to run in debug mode

require_once($yii);//Contains Yii framework
Yii::createWebApplication($config)->run ();//Create an application instance based on the main configuration file and run it. You can access this instance through Yii::app() from anywhere in the current application.


2. Main configuration file
Save location: your application/protected/config/main.php
File content: The general format is as follows:
return array(
'basePath'=>dirname(__FILE__ ).DIRECTORY_SEPARATOR.'..', //The absolute physical path of the current application root directory
'name'=>'Yii Blog Demo', //The name of the current application

//Preload the log (record) application Components, which means that the application components will be created regardless of whether they are accessed. The application's parameter configuration is set in the array with "components" as the keyword below.
'preload'=>array('log'), //log is the component ID

//Auto-loaded model and component class
'import'=>array(
'application.models.*', //Load the "application/models/" folder All model classes
        'application.components.*', //Load all application component classes in the "application/components/" folder
   ),

  'defaultController'=>'post', //Set the default control Device class

// Component configuration of the current application. For more configuration components, see "Core Application Components" below
'components'=>array(
'user'=>array( //user( User) component configuration, "user" is the component ID
              // Cookie-based authentication can be used
            'allowAutoLogin'=>true, // Allow automatic login

      ),
    //URL routing manager
    'urlManager'=>array(
            'urlFormat'=>'path', //URL format. Two formats are supported: 'path' format (such as: /path/to/EntryScript.php/name1/value1/name2/value2...) and 'get' format (such as: /path/to/EntryScript.php? name1=value1&name2=value2...). When using the 'path' format, you need to set the following rules:
            'rules'=>array( //URL rules. Syntax:
                                                                                                                                                       >/<.>&title
