First configure the components.

For convenience, our cache component is configured in the common\config\main.php file. First, let’s simply configure the file cache

'components' => [ 
    'cache' => [ 
        'class' => 'yii\caching\FileCache', 
        'cachePath' => '@runtime/cache2', 
    ], 
],

The default cache path is the @app\runtime\cache directory Next, if you want to modify the cache path, you can configure cachePath like the above configuration.

Let’s do it directly

$cache = Yii::$app->cache; 
$data = $cache->get('cache_data_key'); 
if ($data === false) { 
    //这里我们可以操作数据库获取数据，然后通过$cache->set方法进行缓存 
    $cacheData = ...... 
    //set方法的第一个参数是我们的数据对应的key值，方便我们获取到 
    //第二个参数即是我们要缓存的数据 
    //第三个参数是缓存时间，如果是0，意味着永久缓存。默认是0 
    $cache->set('cache_data_key', $cacheData, 60*60); 
} 
var_dump($data);
