Memcached::getAllKeys — Gets the keys stored on all the servers

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.

此函数没有参数。

Returns the keys stored on all the servers on success 或者在失败时返回 FALSE.
