Smarty中的注释和截断功能介绍_php模板

注释

{* 这是一个单行Smarty注释 来自于jb51.net，网页源代码里看不见*}

{* 这是一个多行
Smarty注释
并不发送到浏览器
*}

模板注释由星号包围，继而由分隔符包围，型如：{* 这是一个注释 *}。Smarty注释不会在最终模板的输出中显示，这点和不同。前者对于在模板中插入内部注释有用，因为没有人能看到。;-)

截断truncate

$smarty->assign('hxtitle', 'Two Sisters Reunite after Eighteen Years at Checkout Counter.');

模板为：

{$hxtitle}
{$hxtitle|truncate}
{$hxtitle|truncate:30}
{$hxtitle|truncate:30:""}
{$hxtitle|truncate:30:"---"}
{$hxtitle|truncate:30:"":true}
{$hxtitle|truncate:30:"...":true}
{$hxtitle|truncate:30:'..':true:true}

输出为：

Two Sisters Reunite after Eighteen Years at Checkout Counter.
Two Sisters Reunite after Eighteen Years at Checkout Counter.
Two Sisters Reunite after...
Two Sisters Reunite after
Two Sisters Reunite after---
Two Sisters Reunite after Eigh
Two Sisters Reunite after E...
Two Sisters Re..ckout Counter.

可以不用在PHP里截取了：http://www.itlearner.com/code/smarty_cn/language.modifier.truncate.html
