Memcached::getAllKeys(PECL memcached >= 2.0.0) Memcached::getAllKeys — Gets the keys stored on all the servers 설명
public array Memcached::getAllKeys
( void
)
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. 인수이 함수는 인수가 없습니다. 반환값
