本文就是和大家分享一款由php结合ajax实现的无刷新留言板，先给大家看一下最后的效果图：

数据库连接代码如下：

<&#63;php
$conn = @mysql_connect("localhost","root","root") or die ("MySql连接错误");
mysql_select_db("demo",$conn);
mysql_query("set names 'utf8'");
&#63;>

index.php文件代码如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link href="bbs.css" type="text/css" rel="stylesheet">
<title>无刷新显示回帖</title>
<script src="bbs.js" type="text/javascript"></script>
</head>

<body>
<h1>无刷新显示回帖</h1>
<div id="thread">
<&#63;php
include("conn.php");
$sql = "select * from `bbs_post` where `threadid` ='1' order by id asc";
$query =mysql_query($sql);
while($row = mysql_fetch_array($query)){ 
&#63;>
 <div class="post" id="post<&#63;php echo $row['id'];&#63;>">
    <div class="post_title"><&#63;php echo $row['title'];&#63;> [<&#63;php echo $row['username'];&#63;>]</div>
    <div class="post_content"><pre class="brush:php;toolbar:false"><&#63;php echo $row['content'];&#63;>
