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。 

复制代码代码如下:

<?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: 

复制代码代码如下:

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

index.tpl: 

复制代码代码如下:

{$articleTitle} 
{$articleTitle|strip_tags} 

输出结果： 

复制代码代码如下:

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： 

复制代码代码如下:

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