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

strip_tags() 函数剥去 HTML、XML 以及 PHP 的标签。

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

smarty中可以使用strip_tags去除html标签,包括在< >之间的任何内容。

例如:

index.php:

$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’);

index.tpl:

{$articleTitle}
{$articleTitle|strip_tags}

输出结果：

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.

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