I do not have MemcacheAdmin on the server, but I need to update a specific cache. How to do it?

memcache->flush() - flushes the entire cache

upd : memcache->delete('key'); You can, of course, delete a certain cache, and wait until it is updated.

    Set the recording lifetime from the app.

     $memcache->set('var_key', 'some really big variable', MEMCACHE_COMPRESSED, 50);

    And yes, for very rarely updated data, it makes sense to do memcache->delete('key'); This is a cache.

    If you constantly need this data, then look in the direction of key-value storage
