原文
作为一个PHP开发人员,我有时被要求作个shoutbox 。 如果同样的事情也发生在你身上,这里有一个快速指南。显然,您要为它添加您自己的CSS在上面,但这里是基本思路。 我们需要一个MySQL数据库表和三个PHP文件。 首先,我们需要一个文件保存数据库信息 --- 文件 #1:mysql.inc.php--- <?php # Simply Shouting - ashoutboxexample # File name:mysql.inc.php # Description: A file to hold database info. $host ='localhost'; $user ='database_user_name'; $password='database_user_password'; $name ='database_name'; ?> 创建一个有四个字段的数据表. 我们命名为shouts. 此前可能你没有这个SQL文件, 创建一个PHP文件"install.php". 这个文件用过一次之后,记得要删除它! -- 文件 #2: install.php-- <?php # Simply Shouting - ashoutboxexample # File name: install.php # Description: Creates the database table. // include the database info file include("mysql.inc.php"); //连接数据库 $connection= @mysql_connect($host,$user,$password) or die(mysql_error()); $db= @mysql_select_db($name,$connection) or die(mysql_error()); //如果我们已经有一个表名字叫做"shouts", 需要先删除它 $sql='DROP TABLE IF EXISTS `shouts`'; $result= @mysql_query($sql,$connection) or die(mysql_error()); // 现在确定没有相同名字的表, 创建它 $sql='CREATE TABLE `shouts` ( `id` int(11) NOT NULL auto_increment, `timestamp` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, `shoutby` varchar(50) default NULL, `shout` varchar(50) default NULL, PRIMARY KEY `id` (`id`) ) TYPE=MyISAM AUTO_INCREMENT=1'; echo'Creating table: \'shouts\'....'; // 关闭连接 $result= @mysql_query($sql,$connection) or die(mysql_error());?> <html> <head> <title>Simply Shouting - 安装</title> </head> <body> <br /> 你的安装过程已经完成. 请立即从你的服务器上删除所有安装文件. 本程序包含以下安装文件:<br /> <br /> 1) install.php<br /> <br /> <br /> <!-- I could just send them to index.phpautomatically, but then they'd wonder if it created correctly or not. --> 点击 <a href="index.php">这里</a>开始.</html> 这是主文件: --- 文件 #3: index.php--- <? # Simply Shouting - ashoutboxexample # File name: index.php # Description: Main page to display our shouts. //包含数据库信息 include_once("mysql.inc.php"); //连接数据库 $connection= @mysql_connect($host,$user,$password) or die(mysql_error()); $db= @mysql_select_db($name,$connection) or die(mysql_error()); ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><style type="text/css"> <!-- body,td,th { font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 12px; } --> </style><body> <div style="width:500px;height 400px; border:thin groove #519554;"> <? // 显示最新10条留言. 首先,初始化一个计数器 $counting=0; // we need a counter because I want to show our shouts in ASC order // (like a chat room) $sql=mysql_query("SELECT * FROM `shouts`"); while($data=mysql_fetch_array($sql)){ //counts every row $counting=$counting+1; } //end while // if the count comes back greater than 10, then we select the last // 10 shouts for display. if($counting>10){ $countlessten=$counting-9; $sql=mysql_query("SELECT * FROM `shouts` ORDER BY `shouts`.`id` ASC LIMIT $countlessten,10"); }else{ //else it doesn't matter, there's less than 10! $sql=mysql_query("SELECT * FROM `shouts` ORDER BY `shouts`.`id` ASC LIMIT 10"); } while($data=mysql_fetch_array($sql)){ //my timestamp field in the database is basically useless to me unless //I parse it.
