smarty現在顯示字數的各種寫法

是否有限制顯示字數的功能啊

有！用truncate
從字符串開始處截取某長度的字符.默認是80個.
你也可以指定第二個參數作爲追加在截取字符串後面的文本字串.該追加字串被計算在截取長度中。
默認情況下,smarty會截取到一個詞的末尾。
如果你想要精確的截取多少個字符,把第三個參數改爲"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.
