view为空，输出不了，为什么？

源自：6-10 Smarty实例

index.php

require_once('function.php');

require_once('config.php');

//对smarty初始化

$view=ORG('Smarty/','Smarty',$viewconfig);

//设置允许的控制器名和方法名数组

$controllerAllow=array('test','index');

$methodAllow=array('test','index','show');

//in_array函数作用：判断一下这个字符串是否存在于字符串里

$controller=in_array($_GET['controller'],$controllerAllow)?daddslashes($_GET['controller']):'index';

$method=in_array($_GET['method'],$methodAllow)?daddslashes($_GET['method']):'index';

C($controller,$method);

testController

class testController{

function show(){

global $view;

$testModel = M('test');

$data=$testModel->get();

var_dump($view);

$view->assign('str','哈哈哈');

$view->display('test.tpl');

}

提示出错：Call to a member function assign() on a non-object
