一个PHP命名空间的问题很无语的问题.

php name space

  直接上点小代码


<?php//用来定义一个继承Smarty的子类,在构造函数中实现基本的路径配置.....namespace Smarty;class Smarty_Test  {    function setName(){    	echo 'Name';    }}
Copy after login


<?phpuse Smarty\Smarty_Test;$smarty = new Smarty_Test();$smarty->assign('name','Ned');$smarty->debugging = true;$smarty->display('index.tpl');?>
Copy after login


代码如上,很简单,两段代码的文件结构在同一个目录下

就这样,运行死活说找不到类..........
Fatal error: Class 'Smarty\Smarty_Test' not found in ............
实在是没搞明白,我在ThinkPHP框架里也是使用命名空间完全没问题,怎么新建一个项目放连个文件,测试一下它死活都不行呢....连ZEND STUDIO编辑器都能显示出有存在Smarty_Test这个类,怎么运行的时候就是不行,,郁闷啊

没人吗..............

很不错LLL

你没有加载含有 Smarty_Test 类定义的文件

你没有加载含有 Smarty_Test 类定义的文件



如何加载?使用include包含进去是吗?

是的,include包含进来
或者设置自动加载

spl_autoload_register();use Smarty\Smarty_Test; $smarty = new Smarty_Test();$smarty->assign('name','Ned');$smarty->debugging = true;$smarty->display('index.tpl');
Copy after login
