    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

    2 include_once 'SmartyZip.php';

    3 $smarty = SmartyZip::init(new Smarty);

    4 $smarty->assign ( 'name', 'SmartyZip' );

    5 $smarty->display ( 'test.html' );

    6 ?>
