对php里边的超级全局数组变量信息的使用
例如：$_GET、$_POST、$_SESSION、$_COOKIE、$_REQUEST、$_SERVER、$_ENV、$GLOBALS、$_FILES、常量信息
{$smarty.get.xxx}
{$smarty.post.xxx}
{$smarty.session.xxx}
{$smarty.cookies.xxx}
{$smarty.request.xxx}
{$smarty.server.xxx}
{$smarty.env.xxx}
目录结构
代码示例：
1.php
<?php define("HOST","0911"); include "./libs/Smarty.class.php"; $smarty = new Smarty; $smarty -> setTemplateDir("./View/"); $smarty -> setCompileDir("./View_c/"); $smarty -> assign('name', $_GET['name']); $smarty -> display('01.html');
/view/1.html
<body> <h2>保留变量使用</h2> <div><?php echo $_GET['name']; ?></div> <div>{$name}</div> <div>名字：{$smarty.get.name}</div> <div>年龄：{$smarty.get.age}</div> <div>主机名：{$smarty.const.HOST}</div> <div>时间戳：{$smarty.now}</div> <div>当前模板名称：{$smarty.template}</div> <div>模板目录名称：{$smarty.current_dir}</div> <div>模板引擎版本：{$smarty.version}</div> <div>模板引擎定界符：{$smarty.ldelim}--{$smarty.rdelim}</div> </body>
