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"> <?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 ".$_COOKIE["nick"]." <a href=?tj=out>退出房间</a>";}else{echo "请输入您的昵称";}?></td> </tr> <tr> <td bgcolor="#F5E6C1"><form action="" method="post"><input type="text" name="nick" cols="20"><input type="submit" name="submit" value="登录"></form></td> </tr></table><table width="80%" border="0" cellspacing="0" cellpadding="0"> <tr> <td> </td> </tr></table><table width="250" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#CBB486"> <tr> <td height="70" bgcolor="#F5E6C1" class="login">程序说明:因本聊天室是作者仅花了一天时间而写的程序,所以仅适合新手练习研究,高手可以进行绕行,新手可以在本基础上进行增加发言IP和其它字段功能,最主要的是理解本程序的制作原理。欢迎新手朋友加入夏日源码交流群:<SPAN id="qid">101140934</SPAN></td> </tr></table></body></html>
四、用户发言页面speak.php如下:
<html><head><title>简单的php+mysql聊天室--发言页</title><link href="style.css" rel="stylesheet" type="text/css" /></head><body><table width="80%" border="0" cellspacing="0" cellpadding="0"> <tr> <td height="2"></td> </tr></table><form action="show.php" target="mainFrame" method="post"> 发言表情:<input type="radio" value="1" name="face" checked="checked" /><img src="face/PIC1.GIF" width="20" height="20" border="0" /><input type="radio" value="2" name="face" /><img src="face/PIC2.GIF" width="20" height="20" border="0" /><input type="radio" value="3" name="face" /><img src="face/PIC3.GIF" width="20" height="20" border="0" /><input type="radio" value="4" name="face" /><img src="face/PIC4.GIF" width="20" height="20" border="0" /><input type="radio" value="5" name="face" /><img src="face/PIC5.GIF" width="20" height="20" border="0" /><input type="radio" value="6" name="face" /><img src="face/PIC6.GIF" width="20" height="20" border="0" /><input type="radio" value="7" name="face" /><img src="face/PIC7.GIF" width="20" height="20" border="0" /> <input type="text" name="words" cols="20"><input type="submit" value="发言"></form></body></html>
五、显示聊天室内容页show.php如下:
<?php require_once('config.php'); ?><?phpif($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($result)){?><table width="700" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#CBB486"> <tr> <td width="33" align="left" bgcolor="#F5E6C1" class="font">昵称:</td> <td width="41" align="center" bgcolor="#F5E6C1" class="font"><?php if($row[nick] == ""){echo "游客";}else{echo $row[nick];}?></td> <td width="42" align="center" bgcolor="#F5E6C1" class="font"><img src="face/PIC<?php echo $row[face];?>.GIF" width="20" height="20"></td> <td width="56" align="left" bgcolor="#F5E6C1" class="font">发言内容:</td> <td width="160" align="left" bgcolor="#F5E6C1" class="font"><?php echo $row[words];?></td> <td width="56" align="left" bgcolor="#F5E6C1" class="font">发言时间:</td> <td width="244" align="left" bgcolor="#F5E6C1" class="font"><?php echo $row[chtime];?></td> </tr></table><table width="100" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td height="5"></td> </tr></table><?php } ?></body></html>
