Memcached keys not showing about phpcacheadmin HOT 1 CLOSED

Your Memcached server is a bit old. My tool uses lru_crawler which requires at least Memcached 1.4.24.

Originally, phpCacheAdmin used cachedump to retrieve all keys but this has many problems. E.g., it randomly displayed a few keys, sometimes it didn't display all of them, and it doesn't show TTL either.

Your fix uses $memcached->getAllKeys() witch works only in Memcached and also has the same problem as cachedump. Memcache and Memcached are different extensions, and my tool must support both of them. I spent a lot of time fixing the compatibility between them, and it's really not an easy task. Overall, both of these extensions are bad.

If you are using Windows, update Memcached server to this version https://github.com/nono303/memcached . I use it with Laragon localhost server. Specifically this version https://github.com/nono303/memcached/tree/master/libevent-2.1/x64

I'm closing this issue because it's a problem with your server and not tool itself.
