smarty中先strip_tags过滤html标签后truncate截取文章运用

<?php echo strip_tags(“Hello <b>world!</b>”); ?>

$smarty = new Smarty;
$smarty->assign(‘articleTitle', “Blind Woman Gets <span style=”font-family: &amp;amp;amp;”>New Kidney</span> from Dad she Hasn't Seen in <strong>years</strong>.”);
$smarty->display(‘index.tpl');

{$articleTitle}
{$articleTitle|strip_tags}

Blind Woman Gets <span style=”font-family: helvetica;”>New Kidney</span> from Dad she Hasn't Seen in <strong>years</strong>.
Blind Woman Gets New Kidney from Dad she Hasn't Seen in years.

{$article.content|truncate:35:”…”:true}
