[TOC] ## 安裝 `composer require easyswoole/fast-cache` ## 注冊,支持落地重啟恢復數據 在`easyswooleEvent.php` 的` mainServerCreate` 方法中注冊 ``` use EasySwoole\FastCache\Cache; use EasySwoole\FastCache\CacheProcessConfig; use EasySwoole\FastCache\SyncData; use EasySwoole\Utility\File; // 每隔5秒將數據存回文件 Cache::getInstance()->setTickInterval(5 * 1000);//設置定時頻率 Cache::getInstance()->setOnTick(function (SyncData $SyncData, CacheProcessConfig $cacheProcessConfig) { $data = [ 'data' => $SyncData->getArray(), 'queue' => $SyncData->getQueueArray(), 'ttl' => $SyncData->getTtlKeys(), // queue支持 'jobIds' => $SyncData->getJobIds(), 'readyJob' => $SyncData->getReadyJob(), 'reserveJob' => $SyncData->getReserveJob(), 'delayJob' => $SyncData->getDelayJob(), 'buryJob' => $SyncData->getBuryJob(), ]; $path = EASYSWOOLE_TEMP_DIR .
