一个PHP命名空间的有关问题.很无语的有关问题.

<br /><?php<br />//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.....<br />namespace Smarty;<br /><br />class Smarty_Test  {<br />    function setName(){<br />    	echo 'Name';<br />    }<br />}<br />

<br /><?php<br />use Smarty\Smarty_Test;<br /><br />$smarty = new Smarty_Test();<br />$smarty->assign('name','Ned');<br />$smarty->debugging = true;<br />$smarty->display('index.tpl');<br />?><br />

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