smarty现在显示字数的各种写法

是否有限制显示字数的功能啊

有！用truncate
从字符串开始处截取某长度的字符.默认是80个.
你也可以指定第二个参数作为追加在截取字符串后面的文本字串.该追加字串被计算在截取长度中。
默认情况下,smarty会截取到一个词的末尾。
如果你想要精确的截取多少个字符,把第三个参数改为"true"

CODE:

index.php:

$smarty =new Smarty;
$smarty->assign('articleTitle','Two Sisters Reunite after Eighteen Years at CheckoutCounter.');
$smarty->display('index.tpl');

index.tpl:

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

OUTPUT:

Two Sisters Reunite after Eighteen Years at Checkout Counter.
