Emlog最新代码实现文章标题加摘要

代码：

<?php
//首页置顶头条
function getZhidingLogs() {
$db = MySql::getInstance();
$sql = 	"SELECT gid,title,content,date FROM ".DB_PREFIX."blog WHERE type='blog' and top='y' ORDER BY `top` DESC ,`date` DESC LIMIT 0,1";
$list = $db->query($sql);
while($row = $db->fetch_array($list)){
//$row['content'] = htmlspecialchars($row['content']);
$row['content'] = strip_tags($row['content']);?>
<h1><a href="<?php echo Url::log($row['gid']); ?>" title="<?php echo $row['title']; ?>" target="_blank"><?php echo $row['title']; ?></a></h1>
<span class="note"><?php echo mb_substr($row['content'],0,85,'utf-8'); ?>...</span><a href="<?php echo Url::log($row['gid']); ?>" class="font2_2" target="_blank">阅读全文&gt;&gt;</a>    
<?php } ?>
<?php } ?>

在需要的地方使用<?php getZhidingLogs();?>调用,输出摘要文字字数请自行修改<?php echo mb_substr($row[‘content’],0,95,’utf-8′);?>这段代码中，中间的95为字数，根据需要调整。
