在视图里我写的片段缓存如图：

<?php

/* @var $this yii\web\View */

$this->title = 'My Yii Application';
?>
<div class="site-index">

    <div class="jumbotron">
        <h1>Congratulations!</h1>

        <p class="lead">You have successfully created your Yii-powered application.</p>

        <p><a class="btn btn-lg btn-success" href="http://www.yiiframework.com">Get started with Yii</a></p>
    </div>

    <div class="body-content">

        <div class="row">
            <div class="col-lg-4">
                <h2>Heading</h2>

                <p><?php
                if ($this->beginCache('key_indexs')) {
                        echo date('Y-d-d H:i:s');
                    
                 }       
                ?></p>

                <p><a class="btn btn-default" href="http://www.yiiframework.com/doc/">Yii Documentation &raquo;</a></p>
            </div>
            <div class="col-lg-4">
                <h2>Heading</h2>

                <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et
                    dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip
                    ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu
                    fugiat nulla pariatur.</p>

                <p><a class="btn btn-default" href="http://www.yiiframework.com/forum/">Yii Forum &raquo;</a></p>
            </div>
        </div>

    </div>
</div>

但浏览时生成的HTML代码如下：


<div class="site-index">

    <div class="jumbotron">
        <h1>Congratulations!</h1>

        <p class="lead">You have successfully created your Yii-powered application.</p>

    </div>

    <div class="body-content">

        <div class="row">
            <div class="col-lg-4">
                <h2>Heading</h2>

为什么beginCache前的HTML都跑到标签前面去了？

配置

[php] view plain copy

1. 'components' => [  
2.     'cache' => [  
3.             'class' => 'yii\caching\FileCache',  
4.         ],

数据缓存

[php] view plain copy

1. $cache = \Yii::$app->cache;  
2. $cache['aa'] = '123';  
3. echo $cache['aa'];

片段缓存

[php] view plain copy

1. <h1>朝代</h1>  
2. <?php if($this->beginCache($id, ['duration' => 3600])) { ?>  
3. <?php  
4. echo ListView::widget([  
5.     'dataProvider' => $dataProvider,  
6.     'itemView' => '_item',  
7. ]);  
8. ?>  
9. <?php $this->endCache(); } ?>  
10.   
11. $dependency = [  
12.     'class' => 'yii\caching\DbDependency',  
13.     'sql' => 'SELECT MAX(updated_at) FROM post',  
14. ];  
15.   
16. if ($this->beginCache($id, ['dependency' => $dependency])) {  
17.   
18.     // ... generate content here ...  
19.   
20.     $this->endCache();  
21. }  
22.   
23. if ($this->beginCache($id, ['variations' => [Yii::$app->language]])) {  
24.   
25.     // ... generate content here ...  
26.   
27.     $this->endCache();  
28. }  
29.   
30. if ($this->beginCache($id1)) {  
31.   
32.     // ...content generation logic...  
33.   
34.     if ($this->beginCache($id2, $options2)) {  
35.   
36.         // ...content generation logic...  
37.   
38.         $this->endCache();  
39.     }  
40.   
41.     // ...content generation logic...  
42.   
43.     $this->endCache();  
44. }

页面缓存

[php] view plain copy

1. class TestController extends Controller  
2. {  
3.     public function actionIndex()  
4.     {  
5.         //$db = \Yii::$app->db;  
6.         sleep(2);  
7.         $query = Dynasty::find();  
8.         $dataProvider = new ActiveDataProvider([  
9.                             'query' => $query,  
10.                             'pagination' => [  
11.                                 'pageSize' => 15,  
12.                             ],  
13.                         ]);  
14.         return $this->render('index', [  
15.             'dataProvider' => $dataProvider  
16.         ]);  
17.     }  
18.     public function behaviors()  
19.     {  
20.         return [  
21.             [  
22.                 'class' => 'yii\filters\PageCache',  
23.                 'duration' => 60,  
24.                                 'variations'=> [$_GET['page']],  
25.             ],  
26.         ];  
27.     }  
28. }

动态内容

[php] view plain copy

1. ...别的HTML内容...  
2. <?php if($this->beginCache($id)) { ?>  
3. ...被缓存的片段内容...  
4.     <?php $this->renderDynamic($callback); ?>  
5. ...被缓存的片段内容...  
6. <?php $this->endCache(); } ?>  
7. ...别的HTML内容...

已有配置：

 'cache' => [
            'class' => 'yii\caching\FileCache',
            'directoryLevel' => 2,
        ],
