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); }
