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

SYNOPSIS

       public array Memcached::getAllKeys (void  )

DESCRIPTION

       Memcached.getAllKeys(3)	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.

PARAMETERS

       This function has no parameters.

RETURN VALUES

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