laravel - 从缓存laravel中的数组获取对象值

Question

我在Redis缓存中有这样的数组

127.0.0.1:6379> MGET laravel:campaign1107
1) "a:1:{s:21:\"unsubscriberCount1107\";i:2;}"
127.0.0.1:6379> 

现在，我需要获取 unsubscriber1107值。我尝试过这种方式

 dd(cache()->get($arrayCacheKey[$cacheKey]));

但是，这是行不通的。如何访问该对象？

我的设置缓存代码

public function updateUnsubscriberCountCache($campaign_id, $type) 
{  
    $assoc = [];
    $arrayCacheKey = 'campaign'.$campaign_id.'';
    $cacheKey = 'unsubscriberCount'.$campaign_id.'';
    if($type == 'unsubscriberLogCount') {
        $cacheKey = 'unsubscriberCount'.$campaign_id.'';
         if( cache()->get($cacheKey) > 0) {
              cache()->increment($cacheKey);
              //cache()->forget($cacheKey); 
            } else {
                $total = UnsubscribeLog::select('unsubscribe_logs.*')->leftJoin('tracking_logs', 'tracking_logs.message_id', '=', 'unsubscribe_logs.message_id')->where('tracking_logs.campaign_id', '=', $campaign_id)->distinct('subscriber_id')->count('subscriber_id');
                 //cache()->forever($cacheKey, $total);
                $assoc[$cacheKey] = $total;
                cache()->forever($arrayCacheKey, $assoc);
            }
        }
    }

您使用$arrayCacheKey将值存储为数组，但是在代码的前面，您尝试使用具有不同值的$cacheKey访问它。

如果要获取unsubscriber1107的值，则需要使用两个键的组合:

$campaignData = cache()->get($arrayCacheKey); //To get the array value from the cache
$count = $campaignData ? $campaignData[$cacheKey] : null; //get the count 

以上假设
