<p>{$myresult}</p>

现在我只是在展示。如何从聪明的内容中只显示25个字符

Answer 1

聪明地使用Truncate ......

<强> CODES

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

<强>输出

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 Re..ckout Counter.

Answer 2

如果安装了子串过滤器（我认为它已安装默认值）：

{$myresult|substring:1:25}

如果没有，请查看此网站：
