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);}
)
