Memcached::setMulti — Store multiple items
$items
   [, int $expiration
  ] )
   Memcached::setMulti() is similar to
   Memcached::set(), but instead of a single key/value
   item, it works on multiple items specified in
   items. The expiration time
   applies to all the items at once.
  
itemsAn array of key/value pairs to store on the server.
expirationThe expiration time, defaults to 0. See Expiration Times for more info.
   Returns TRUE on success or FALSE on failure.
   Use Memcached::getResultCode() if necessary.
