解析smarty 截取字符串函數 truncate的用法介紹

smarty truncate 截取字符串
從字符串開始處截取某長度的字符，默認的長度為80
指定第二個參數作為截取字符串的長度
默認情況下，smarty會截取到一個詞的末尾，
如果需要精確到截取多少個字符可以使用第三個參數，將其設為”true”
具體用法如下：
復制代碼 代碼如下:
//index.php $smarty = new Smarty;
$smarty->assign('articleTitle', 'Two Sisters Reunite after Eighteen Years at Checkout Counter.');
$smarty->display('index.tpl');
//index.tpl
{$articleTitle}
{$articleTitle|truncate}
{$articleTitle|truncate:30}
{$articleTitle|truncate:30:""}
{$articleTitle|truncate:30:"---"}
{$articleTitle|truncate:30:"":true}
{$articleTitle|truncate:30:"...":true}
