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' );
