Memcached::getAllKeys
(PECL memcached >= 2.0.0)
Memcached::getAllKeys — Gets the keys stored on all the servers
Beschreibung
public Memcached::getAllKeys(): array|false
Memcached::getAllKeys() queries each memcache server and retrieves an array of all keys stored on them at that point in time. This is not an atomic operation, so it isn't a truly consistent snapshot of the keys at point in time. As memcache doesn't guarantee to return all keys you also cannot assume that all keys have been returned.
