The example in this article describes the simple php mysql chat room implementation method. Share it with everyone for your reference, the details are as follows:
The program introduced here is divided into 8 files:
frameset frame page:index.php
Show chat room content page: show.php
User login page: login.php
User speaking page: speak.php
Database configuration file: config.php
Page beautification style: style.css
Database file: chat.sql
Speech emoticon package: face/
The respective introductions are as follows:
1. The database file chat.sql is as follows:
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');
2. The frame page is as follows:
<!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>
3. The user login page login.php is as follows:
<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">
<?php
if($_GET["tj"] == "out"){
setcookie ("nick", "", time() - 3600);
header("refresh:0; URL='login.php'");
}
if($_POST["submit"]){
setcookie("nick",$nick); //用cookie记录用户昵称,也可以用SESSION
header("refresh:0; URL='login.php'");
}
?>
<?php if($_COOKIE["nick"]){echo "欢迎您 ".$_COOKIE["nick"]." <a href=?tj=out>退出房间</a>";}else{echo "请输入您的昵称";}?></td>
</tr>
<tr>
<td bgcolor="#F5E6C1">
<form action="" method="post">

<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>
4. The user speech page speak.php is as follows:
<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" width="20" height="20" border="0" /> <input type="radio" value="2" name="face" /> <img src="face/PIC2.GIF" width="20" height="20" border="0" /> <input type="radio" value="3" name="face" /> <img src="face/PIC3.GIF" width="20" height="20" border="0" /> <input type="radio" value="4" name="face" /> <img src="face/PIC4.GIF" width="20" height="20" border="0" /> <input type="radio" value="5" name="face" /> <img src="face/PIC5.GIF" width="20" height="20" border="0" /> <input type="radio" value="6" name="face" /> <img src="face/PIC6.GIF" width="20" height="20" border="0" /> <input type="radio" value="7" name="face" /> <img src="face/PIC7.GIF" width="20" height="20" border="0" /> <input type="text" name="words" cols="20"> <input type="submit" value="发言"> </form> </body> </html>
5. Display the chat room content page show.php as follows:
<?php require_once('config.php'); ?>
<?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'"); }
?>
<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>
<?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)){
?>
<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>
