memcached_mget() is used to select multiple keys at once. For multiple key
operations it is always faster to use this function. This function always
works asynchronously. memcached_fetch() is then used to retrieve any keys

+found. No error is given on keys that are not found. You must call either
+memcached_fetch() or memcached_fetch_result() after a successful call to
+memcached_mget(). You should continue to call these functions until they
+return NULL (aka no more values). If you need to quit in the middle of a
+memcached_get() call, execute a memcached_quit(). After you do this, you can
+issue new queries against the server.
memcached_fetch() is used to fetch an individual value from the server.
memcached_mget() must always be called before using this method. You
help. This function will dynamically allocate a result structure for you
if you do not pass one to the function.
+memcached_get_by_key() and memcached_mget_by_key() behave in a similar nature
+as memcached_get() and memcached_mget(). The difference is that they take
+a master key that is used for determining which server an object was stored
