  @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
