PHP Memcached::deleteByKey方法代码示例

 /**
  * Remove the item from the cache.
  *
  * Remove an item from cache with identified by $key after $time seconds. The
  * $time parameter allows an object to be queued for deletion without immediately
  * deleting. Between the time that it is queued and the time it's deleted, add,
  * replace, and get will fail, but set will succeed.
  *
  * @link http://www.php.net/manual/en/memcached.delete.php
  *
  * @param   string      $key        The key under which to store the value.
  * @param   string      $group      The group value appended to the $key.
  * @param   int         $time       The amount of time the server will wait to delete the item in seconds.
  * @param   string      $server_key The key identifying the server to store the value on.
  * @param   bool        $byKey      True to store in internal cache by key; false to not store by key
  * @return  bool                    Returns TRUE on success or FALSE on failure.
