smarty 截取字符串

<br />
<br />
$str['name'] = "截取字符串长度"<br />
$str['name'] = "取字符串长度"<br />
<br />
<{$$str.name|truncate_cn:"6":"..."}>  这样的话小于6位的也带...   <br />
<br />
怎么判断$str['name'] 的字符是不是大于6啊才加...啊? <br />

------解决方案--------------------
    if (count($t_string[0]) > $length) //如果超过指定长度
        return join('', array_slice($t_string[0], 0, $length)) . $etc; //截取并加上 ...
    return join('', array_slice($t_string[0], 0, $length)) . $etc; //那这句就不对了
应该是
return $string; // 原样返回
