asfop / cache-kv example snippets

// 一行代码搞定：检查缓存 → 未命中则获取数据 → 自动回填缓存
$data = kv_get('user.profile', ['id' => 123], function() {
    return getUserFromDatabase(123); // 只在缓存未命中时执行
});

// 配置Redis连接

    $redis = new Redis();
    $redis->connect('127.0.0.1', 6379);

// 单个数据获取
$user = kv_get('user.profile', ['id' => 123], function() {
    return ['id' => 123, 'name' => 'John', 'email' => '[email protected]'];
});

// 批量数据获取
$users = kv_get_multi('user.profile', [
    ['id' => 1], ['id' => 2], ['id' => 3]
], function($missedKeys) {
    $data = [];
    foreach ($missedKeys as $cacheKey) {
        $keyString = (string)$cacheKey;
        $params = $cacheKey->getParams();
        $data[$keyString] = getUserFromDatabase($params['id']);
    }
    return $data; // 返回关联数组
});

// 批量获取键对象（不执行缓存操作）
$keys = kv_get_keys('user.profile', [
    ['id' => 1], ['id' => 2], ['id' => 3]
]);

// 检查键配置
foreach ($keys as $keyString => $keyObj) {

// 获取统计信息

// 获取热点键
$hotKeys = kv_hot_keys(10);
// ['user:profile:123' => 45, 'user:profile:456' => 32, ...]

// 清空统计数据
