本文实例讲述了YII框架页面缓存操作。分享给大家供大家参考，具体如下：
IndexController.php
namespace frontend\controllers;
use yii;
use yii\web\Controller;
class IndexController extends Controller
{
public function behaviors()//先于action执行,可以用来实现页面缓存
{
return [
[
'class'=>'yii\filters\PageCache',//整个页面缓存
'duration'=>10,//缓存时间
'only'=>['cache'],//只有index操作会被缓存，即使没有视图展示也会缓存
'dependency'=>[
'class'=>'yii\caching\DbDependency',
'sql'=>'select count(*) from user',
],
]
];
}
public function actionCache(){
//片段缓存
return $this->renderPartial("index");
}
}
views/index/index.php
<?php
/**
* Created by PhpStorm.
* Date: 2016/5/25
* Time: 19:37
*/
$duration = 15;
//缓存依赖
$dependency = [
'class'=>'yii\caching\FileDependency',
'fileName'=>'hw.txt',//web目录下
];
//缓存的开关
$enabled = false;
?>
<?php
//if($this->beginCache('cache_div',['duration' => $duration])){
//if($this->beginCache('cache_div',['enabled' => $enabled])){
if($this->beginCache('cache_div',['dependency' => $dependency])){?>
<div id="cache_div">
<div>这里待会会被缓存 哈哈</div>
</div>
<?php
$this->endCache();
}?>
<div id="no_cache_div">
<div>这里不会被缓存 噜</div>
</div>
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
