REDIS的做缓存

$di->setShared('cache', function () {
    $frontCache = new Phalcon\Cache\Frontend\Data([
            "lifetime" => 172800,
        ]);
    $cache=new Phalcon\Cache\Backend\Redis(
        $frontCache,[
            "host"       => "localhost",
            "port"       => 6379,
            "persistent" => false,
            "index"      => 0,
        ]
    );
    return $cache;
});

数据库的跟踪

    $eventsManager = new \Phalcon\Events\Manager();
    //从di中获取共享的profiler实例
    $profiler = $di->getProfiler();
    //监听所有的db事件
    $eventsManager->attach('db', function($event, $connection) use
    ($profiler) {
        //一条语句查询之前事件，profiler开始记录sql语句
        if ($event->getType() == 'beforeQuery') {
            $profiler->startProfile($connection->getSQLStatement());
