Steps to implement web page caching and page chunking using the Yii framework

Introduction:
In the web development process, in order to improve the performance and user experience of the website, it is often necessary to cache and chunk the page deal with. The Yii framework provides powerful caching and layout functions, which can help developers quickly implement web page caching and page chunking. This article will introduce how to use the Yii framework to implement web page caching and page chunking.

1. Web page caching

Enable web page caching
In the Yii framework, web page caching can be turned on through the configuration file. Open the main configuration file config/main.php, find the components node, and add the following code:
```
'cache' => [
 'class' => 'yiicachingFileCache',
]
```
Copy after login
The above code configures a file cache component that can cache the page into the file.

Enabling and using cache in the controller
In the controller that needs caching, it can be enabled by inheriting CController or Controller and use caching. The following is a sample controller:

use yiiwebController;

class SiteController extends Controller
{
 // 开启缓存
 public $cacheDuration = 3600; // 缓存持续时间，单位为秒

 public function behaviors()
 {
     return [
         'pageCache' => [
             'class' => 'yiiiltersPageCache',
             'duration' => $this->cacheDuration,
         ],
     ];
 }
 
 // 缓存和不缓存的action
 public function actions()
 {
     return [
         'index' => 'appwidgetsIndexAction',
         'about' => [
             'class' => 'yiiwebViewAction',
             'layout' => 'about', // 自定义布局
             'cache' => true, // 开启缓存
             'cacheDuration' => $this->cacheDuration, 
         ],
         // ...
     ];
 }

 // ...
}

Copy after login

In the above code example, by inheriting Controller, we can easily use the PageCache filter to implement web page caching. Cache time, layout, etc. can be customized according to needs.

2. Page segmentation

Create a layout file
Create a layout in the views/layouts directory file, such as main.php, and defines the main structure of the page:
```
<!DOCTYPE html>
<html>
<head>
 
</head>
<body>
 <div id="header">
     
 </div>
 
 <div id="content">
     <?= $content ?>
 </div>
 
 <div id="footer">
     
 </div>
</body>
</html>
```
Copy after login
In the above code example, we define a main layout file and use $content Variables to represent the content of different page views.
Using layout and blocking
In the view file, you can achieve the effect of page blocking by specifying layout and blocking. The following is a sample view file:
```
<?php $this->beginContent('path/to/main'); ?>

<div id="sidebar">
 
</div>

<div id="main-content">
 
</div>

<?php $this->endContent(); ?>
```
Copy after login
In the above code example, use the beginContent() and endContent() methods to specify the layout file path. In the layout file, use the $content variable to render the chunked content in the view file.

3. Summary
Through the above steps, we can implement web page caching and page blocking functions in the Yii framework. Turning on web page caching can improve page loading speed and reduce server load, while page chunking can improve code reusability and development efficiency. Using the caching and layout functions provided by the Yii framework, developers can more flexibly manage web page caching and page layout, thereby optimizing the performance and user experience of web applications.

The code examples are only for reference, please modify and adjust appropriately according to actual needs. I hope this article can help you use the Yii framework to implement web page caching and page chunking.
