Cache clear() not working with Redis, getItem() still returns data

[stefanbaas]

The cache clear() function is not working correctly with Redis, getItem('{cachekey}') still returns data, after i cleared the cache with the clear() function. I'm using version 9.1.3. Even after a page refresh the data is not deleted.

use Phpfastcache\CacheManager;
$_cache = CacheManager::getInstance('redis', new Config(array(
    'host' => '127.0.0.1',
    'port' => 6379,
    'password' => '',
    'database' => 0,
    'itemDetailedDate' => true
))); 

// Clear all cache
$_cache->clear();

// Get cache data
$cacheKey = "test";
$item = $_cache->getItem($cacheKey);
$data = $item->get(); // I still get data after $_cache->clear()

When i delete the item with the following function it works correctly, but i want to delete the whole cache.
It's strange because $_cache->getItems() returns an empty array, but $_cache->getItem("test") is returning data.
$_cache->deleteItem("test");

Hello

As per PSR6: https://www.php-fig.org/psr/psr-6/

 * Returns a Cache Item representing the specified key.
*
* This method must always return a CacheItemInterface object, even in case of
* a cache miss. It MUST NOT return null.
*

It is by design so.
