本文实例讲述了简单的php+mysql聊天室实现方法。分享给大家供大家参考，具体如下：

这里介绍的程序分为 8 个文件：

frameset框架页面:index.php

显示聊天室内容页：show.php

用户登陆页面：login.php

用户发言页面：speak.php

数据库配置文件：config.php

页面美化样式：style.css

数据库文件：chat.sql

发言表情包：face/

分别介绍如下：

一、数据库文件chat.sql如下：

SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for `chat`
-- ----------------------------
DROP TABLE IF EXISTS `chat`;
CREATE TABLE `chat` (
 `chtime` datetime default NULL,
 `nick` char(10) NOT NULL,
 `words` char(150) default NULL,
 `face` int(11) default NULL
) ENGINE=InnoDB DEFAULT CHARSET=gb2312;
-- ----------------------------
-- Records of chat
-- ----------------------------
INSERT INTO chat VALUES ('2013-03-21 04:15:14', 'smiling', '测试显示发言', '3');
INSERT INTO chat VALUES ('2013-03-21 04:46:26', 'smiling', '时间有问题，', '5');
INSERT INTO chat VALUES ('2013-03-21 04:47:28', 'php新手', '新手来了。', '1');
INSERT INTO chat VALUES ('2013-03-21 04:55:19', 'php新手', '显示正确啦', '6');
INSERT INTO chat VALUES ('2013-03-21 17:12:47', 'php新手', '正确显示时间', '5');
INSERT INTO chat VALUES ('2013-03-21 17:23:19', 'php新手', '时间显示正确。', '7');
INSERT INTO chat VALUES ('2013-03-21 17:23:29', 'php新手', '哈哈', '1');
INSERT INTO chat VALUES ('2013-03-22 08:28:00', '', '今天再来看看。', '3');

二、框架页面如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>简单的php+mysql聊天室--框架页</title>
</head>
<frameset rows="*,80" cols="*" framespacing="0" bordercolor="#E1D1AE">
 <frameset rows="*" cols="*,284">
  <frame src="show.php" name="mainFrame"/>
  <frame src="login.php" name="rightFrame"/>
 </frameset>
 <frame src="speak.php" name="bottomFrame"/>
</frameset>
<noframes><body>
</body>
</noframes>
</html>

三、用户登陆页面login.php如下：

<html>
<head>
<title>简单的php+mysql聊天室--登陆页</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="80%" border="0" cellspacing="0" cellpadding="0">
 <tr>
  <td> </td>
 </tr>
</table>
<table width="250" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#CBB486">
 <tr>
  <td height="30" align="center" bgcolor="#F5E6C1">
    <&#63;php 
    if($_GET["tj"] == "out"){
    setcookie ("nick", "", time() - 3600);
    header("refresh:0; URL='login.php'");
    }
    if($_POST["submit"]){
    setcookie("nick",$nick); //用cookie记录用户昵称,也可以用SESSION
    header("refresh:0; URL='login.php'");
    }
    &#63;>
    <&#63;php if($_COOKIE["nick"]){echo "欢迎您 ".$_COOKIE["nick"]." <a href=&#63;tj=out>退出房间</a>";}else{echo "请输入您的昵称";}&#63;></td>
 </tr>
 <tr>
  <td bgcolor="#F5E6C1">
<form action="" method="post">
<input type="text" name="nick" cols="20">
<input type="submit" name="submit" value="登录">
</form></td>
 </tr>
</table>
<table width="80%" border="0" cellspacing="0" cellpadding="0">
 <tr>
  <td> </td>
 </tr>
</table>
<table width="250" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#CBB486">
 <tr>
  <td height="70" bgcolor="#F5E6C1" class="login">程序说明：因本聊天室是作者仅花了一天时间而写的程序，所以仅适合新手练习研究，高手可以进行绕行，新手可以在本基础上进行增加发言IP和其它字段功能，最主要的是理解本程序的制作原理。欢迎新手朋友加入夏日源码交流群：<SPAN id="qid">101140934</SPAN></td>
 </tr>
</table>
</body>
</html>

四、用户发言页面speak.php如下：

<html>
<head>
<title>简单的php+mysql聊天室--发言页</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="80%" border="0" cellspacing="0" cellpadding="0">
 <tr>
  <td height="2"></td>
 </tr>
</table>
<form action="show.php" target="mainFrame" method="post">
  发言表情：
<input type="radio" value="1" name="face" checked="checked" />
<img  src="face/PIC1.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >
<input type="radio" value="2" name="face" />
<img  src="face/PIC2.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >
<input type="radio" value="3" name="face" />
<img  src="face/PIC3.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >
<input type="radio" value="4" name="face" />
<img  src="face/PIC4.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >
<input type="radio" value="5" name="face" />
<img  src="face/PIC5.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >
<input type="radio" value="6" name="face" />
<img  src="face/PIC6.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >
<input type="radio" value="7" name="face" />
<img  src="face/PIC7.GIF"    style="max-width:90%"  style="max-width:90%" border="0" / alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >　
<input type="text" name="words" cols="20">
<input type="submit" value="发言">
</form>
</body>
</html>

五、显示聊天室内容页show.php如下：

<&#63;php require_once('config.php'); &#63;>
<&#63;php
if($words){
$query="insert into chat(chtime,nick,words,face)values(now(),'$nick','$words','$face')";//插入SQL语句
mysql_query($query,$link_ID); //发送留言到数据库
header("refresh:0; URL='show.php'"); }
&#63;>
<html>
<head>
<title>简单的php+mysql聊天室--显示留言页</title>
<link href="style.css" rel="stylesheet" type="text/css" />
<meta http-equiv="refresh" content="5;url=show.php">
</head>
<body>
<&#63;php 
    //最新发言显示在最下面
    $sql="select * from chat order by chtime asc";
    $result=mysql_query($sql);
    $total=mysql_num_rows($result);
    $info=($total/15-1)*15;
    if($total<15){
    $str="select * from chat order by chtime asc;" ; //查询字符串
    }else{
    $str="select * from chat order by chtime asc limit $info,15;" ; //查询字符串
    }
     $result=mysql_query($str,$link_ID); //送出查询
     while($row=mysql_fetch_array($result)){
&#63;>
<table width="700" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#CBB486">
 <tr>
  <td width="33" align="left" bgcolor="#F5E6C1" class="font">昵称:</td>
  <td width="41" align="center" bgcolor="#F5E6C1" class="font"><&#63;php if($row[nick] == ""){echo "游客";}else{echo $row[nick];}&#63;></td>
  <td width="42" align="center" bgcolor="#F5E6C1" class="font"><img  src="face/PIC<&#63;php echo $row[face];&#63; alt="简单的php+mysql聊天室实现方法(附源码)_PHP" >.GIF" width="20"    style="max-width:90%"></td>
  <td width="56" align="left" bgcolor="#F5E6C1" class="font">发言内容:</td>
  <td width="160" align="left" bgcolor="#F5E6C1" class="font"><&#63;php echo $row[words];&#63;></td>
  <td width="56" align="left" bgcolor="#F5E6C1" class="font">发言时间:</td>
  <td width="244" align="left" bgcolor="#F5E6C1" class="font"><&#63;php echo $row[chtime];&#63;></td>
 </tr>
</table>
<table width="100" border="0" align="center" cellpadding="0" cellspacing="0">
 <tr>
  <td height="5"></td>
 </tr>
</table>
<&#63;php } &#63;>
</body>
</html>
