@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 />

新建 tpl/default/ttt.html 
新建 tpp目录 ok了
