@ Kangsheng Weibo Template Extraction Class I think this template is easy to use. Take some time to make it independently.by Lei Rijin
@ took a look at the ctt template. Is it similar to the phpcms template? ? ^_^ Hehe! ! !
@ Weibo http://weibo.com/lrjxgl
@ Everyone shares the good stuff. If you have any questions about the extraction, please ask
@ The default template file is .htm

復(fù)制代碼 代碼如下:

< ;html xmlns="http://www.w3.org/1999/xhtml">





1. String assignment:

{$str}


2. Array assignment:< br />
{loop $a $v}{$v},{/loop}
or

{loop $a $key $val }{$val},{/loop}
3 .{$subhtml}

{subtpl ttt}

4. Originally I was {$indexurl } and now I have been turned into index.php

5.I I can also echo it

{echo $ec}

6. In fact, I can also add, subtract, multiply and divide 6*7*8
{echo 6*7*8;}
7. These are the commonly used ones, what else don’t you understand

The above introduces the template class of discuz x2.5 extracted from the Kangsheng product discuz, including the content of discuz x2.5. I hope it will be helpful to friends who are interested in PHP tutorials.
