?>使用Smarty很简单：
1. 包含SmartyZip文件。
2. 使用SmartyZip::init(new Smarty)自动为smarty对象设置默认路径。
样例代码：view sourceprint?1 <?php
include_once 'SmartyZip.php';
$smarty = SmartyZip::init(new Smarty);
$smarty->assign('name', 'SmartyZip');
$smarty->display('test.<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=html">html</SPAN>');
?>
