yii2缓存cache使用

1 默认cache 默认保存路径/basic/runtime/cache/

Yii::$app->cache->set('name','huyongjian');
$v = Yii::$app->cache->get('name');

2 cache使用redis保存

a 安装redis (yii2使用redis)
b /basic/config/web.php components添加
'cache' => [
            'class' => 'yii\redis\Cache',
        ],
        'redis' => [
            'class' => 'yii\redis\Connection',
            'hostname' => '127.0.0.1',
            'port' => 6379,
            'database' => 10,
        ],
d 测试
Yii::$app->cache->set('name','huyongjian');
$v = Yii::$app->cache->get('name');
$name = Yii::$app->redis->get('name');
var_dump($name);
