当我尝试在 CakePhp 中为计数器设置 Apc 缓存时，
Cache::config('counters', array(
'engine' => 'Apc',
'duration' => 3600,
'prefix' => Inflector::slug(APP_DIR) . 'counters_',
));
它显示以下错误：
Fatal error: Uncaught exception 'CacheException' with message 'Cache engine counters is
not properly configured.' in /home/mysite/www/lib/Cake/Cache/Cache.php:181
Stack trace: #0 /home/mysite/www/lib/Cake/Cache/Cache.php(151):

但是，如果我检查 phpinfo，它会显示以下内容：

如何正确设置和使用 CakePHP 的 Apc 缓存？
非常感谢你的帮助 ！
