@ 好东西大家共享 磕磕绊绊的提取出来 有问题请提出来
@ 模板文件默认为 .htm

新建 tpl/default/index.html
复制代码 代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>

<body>
1.字符串赋值 :<br />
{$str}
<br />
2.数组赋值 :<br />
{loop $a $v}{$v},{/loop}
或者<br />
{loop $a $key $val }{$val},{/loop}

3.{$subhtml}<br />
{subtpl ttt}<br />
4.原来我是{$indexurl } 现在我被变成了index.php<br />
5.我还可以 echo 出来呢<br />
{echo $ec}<br />
6.其实我还可以加减乘除的 6*7*8
{echo 6*7*8;}
7.常用的就这些了 还有什么不懂的 <br />

</body>
</html>
