可能重复：
无法打开流：参数无效
// Define the core paths
// Define them as absolute paths to make sure that require_once works as expected
// DIRECTORY_SEPARATOR is a PHP pre-defined constant
// (\ for Windows, / for Unix)
defined('DS') ? null : define('DS', DIRECTORY_SEPARATOR);
defined('SITE_ROOT') ? null :
define('SITE_ROOT', DS.'C:'.DS.'wamp'.DS.'www'.DS.'photo_gallery');
defined('LIB_PATH') ? null : define('LIB_PATH', SITE_ROOT.DS.'includes');
// load config file first
require_once(LIB_PATH.DS.'config.php');
// load basic functions next so that everything after can use them
require_once(LIB_PATH.DS.'functions.php');
// load core objects
require_once(LIB_PATH.DS.'session.php');
require_once(LIB_PATH.DS.'database.php');
// load database-related classes
require_once(LIB_PATH.DS.'user.php');
每当我尝试通过在地址栏 localhost/photo_gallery/public/admin/index.php 中输入来运行此代码。它将显示如下错误：
警告：require_once(\C:\wamp\www\photo_gallery\includes\config.php)：未能打开流：C:\wamp\www\photo_gallery\includes\initialize.php 中的参数无效，第 16 行。
致命错误：require_once()：在 C:\wamp\www\photo_gallery 中打开所需的 '\C:\wamp\www\photo_gallery\includes\config.php'(include_path='.;C:\php\pear') 失败\includes\initialize.php 在第 16 行
请告诉我该怎么办？我是一个初学者启动网页设计师，我被这个致命错误卡住了。
