php 用spl_autoload时，传来的命名空间分割符是，这个在linux上出问题

<code>public static function init() {
    require_once (__DIR__ . '/functions.php');
    // 自动加载设置
    spl_autoload_register('self::loadClass');
    define("ROOT", getcwd());
    define('APP', ROOT . '/' . Config::get('app.app_name'));
    // 设置时区
    ini_set('date.timezone', Config::get('app.timezone'));
    $router = new Router();
    // 加载路由设置
    require_once (APP . '/routes.php');
    $router->dispatch();
}

public static function loadClass($className) {
    // linux上路径
    $className = str_replace("\\", "/", $className);
    $filename = ROOT . "/" . $className . ".php";
    if(is_file($filename))
        require_once($filename);
    else
        throw new \Exception("$filename Is Not Found");
}</code>
