几种缓存，需要用到前端配置，加后端实例配合着用

片段缓存：

public function indexAction()    {        //渲染页面        $this->view->setTemplateAfter('common');        //缓存片段         //前端配置        $frontcache = new \Phalcon\Cache\Frontend\Output(array(            "lifetime" => 86400        )); 　　　　　　//后端处理        $cache = new \Phalcon\Cache\Backend\File($frontcache, array(            "cacheDir" => "../app/cache/"        ));        //查询片段是否存在        $content = $cache->start("index.pthm");        if ($content == null) {            echo date("r");            $this->view->pick("index/index");            //缓存片段            $cache->save();        } else {            echo $content;        }    }

　　

文件缓存：

public function lastAction()    {        //数据缓存        //前端配置        $frontcache = new \Phalcon\Cache\Frontend\Data(array(            "lifetime"=>86400        ));        //后端实例        $cache = new \Phalcon\Cache\Backend\File($frontcache, array(            'cacheDir'=>'../app/cache/'        ));        $cacheKey = 'customer_10';        $customer = $cache->get($cacheKey);        //在3600有效期内读取缓存       // $customer = $cache->get($cacheKey, 3600);        if($customer == null)        {            $customer = \SysCustomer::find(array(                "limit"=>10            ))->toArray();            //保存缓存            $cache->save($cacheKey, $customer);            //单独设置缓存的有效期            // $cache->save($cacheKey, $customer,3600);        }        var_dump($customer);    }

　　

注意：MainTask.php

如果你是命令行运行MainTask.php，在用文件缓存的时候，如果设置的是cacheDIR='/',以windows为例，我的php盘是f:\，那么生成的缓存文件在 f:\ 根目录下

 

 

 

 

 

 

memcache缓存,本例是windows下：

public function memcacheAction()    {        //memcache缓存        //前端配置有效期        $frontcache = new \Phalcon\Cache\Frontend\Data(array(            "lifetime"=>86400        ));        //后端实例化        $memcache =  new \Phalcon\Cache\Backend\Memcache($frontcache, array(            "servers" => array(                array(                    "host" => "127.0.0.1",                    "port" => "11211",                    "weight" => "1"                )            )        ));       $mydata = $memcache->get('my-data');        if($mydata == null) {            $mydata = array(1,2,3,4,5);            //保存缓存            $memcache->save('my-data', $mydata);            echo "--";        }        var_dump($mydata);    }
