Memcached::getAllKeys

(PECL memcached >= 2.0.0)
Gets the keys stored on all the servers
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.

Returns:

Returns the keys stored on all the servers on success or FALSE on failure.
