## 安装
`composer require easyswoole/fast-cache`
## 注册,支持落地重启恢复数据
在`easyswooleEvent.php` 的` mainServerCreate` 方法中注册
```
use EasySwoole\FastCache\Cache;
use EasySwoole\FastCache\CacheProcessConfig;
use EasySwoole\FastCache\SyncData;
use EasySwoole\Utility\File;
// 每隔5秒将数据存回文件
Cache::getInstance()->setTickInterval(5 * 1000);//设置定时频率
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 . '/FastCacheData/' . $cacheProcessConfig->getProcessName();
File::createFile($path,serialize($data));
});
// 启动时将存回的文件重新写入
Cache::getInstance()->setOnStart(function (CacheProcessConfig $cacheProcessConfig) {
$path = EASYSWOOLE_TEMP_DIR . '/FastCacheData/' . $cacheProcessConfig->getProcessName();
if(is_file($path)){
$data = unserialize(file_get_contents($path));
$syncData = new SyncData();
$syncData->setArray($data['data']);
$syncData->setQueueArray($data['queue']);
$syncData->setTtlKeys(($data['ttl']));
// queue支持
$syncData->setJobIds($data['jobIds']);
$syncData->setReadyJob($data['readyJob']);
$syncData->setReserveJob($data['reserveJob']);
$syncData->setDelayJob($data['delayJob']);
$syncData->setBuryJob($data['buryJob']);
return $syncData;
}
});
// 在守护进程时,php easyswoole stop 时会调用,落地数据
Cache::getInstance()->setOnShutdown(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 . '/FastCacheData/' . $cacheProcessConfig->getProcessName();
File::createFile($path,serialize($data));
});
Cache::getInstance()->setTempDir(EASYSWOOLE_TEMP_DIR)->attachToServer(ServerManager::getInstance()->getSwooleServer());
```
## 使用
```
use EasySwoole\FastCache\Cache;
Cache::getInstance()->set('get','a');
var_dump(Cache::getInstance()->get('get'));
```
