smarty truncate 截取字符串長度

smarty truncate 截取
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為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,把第三個參數改為"true" 。


例 截取:

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

index.tpl:
{$articleTitle}

{$articleTitle|truncate:30}
{$articleTitle|truncate:30:""}
