@康盛微博 模板提取类 觉得这个模板好用 花些时间独立出来。 by 雷日锦
@看了一下ctt 这个模板 跟 phpcms的模板类似 难道？？ ^_^ 嘿嘿！！！
@ 微博 http://weibo.com/lrjxgl
@ 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

<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>

新建 tpl/default/ttt.html
新建 tpp目录 ok了
