从康盛产品(discuz)提取出来的模板类

复制代码代码如下:

<?php

/*template.class.php

@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

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">

<head>

<title>无标题文档</title>

</head>

<body>

1.字符串赋值 :

{$str}

2.数组赋值 :

{loop $a $v}{$v},{/loop}

或者

{loop $a $key $val }{$val},{/loop}

3.{$subhtml}

{subtpl ttt}

4.原来我是{$indexurl } 现在我被变成了index.php

5.我还可以 echo 出来呢

{echo $ec}

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

</body>

</html>

新建 tpl/default/ttt.html

新建 tpp目录 ok了
