PHP5与MySQL数据库操作常用代码收集-木庄网络博客

1 建立数据库表：

代码如下:

create database club;
create table member(
id int(11) not null auto_increment,
no varchar(5) not null,
name varchar(10) not null,
age int(2) not null,
level varchar(10) not null,
sex tinyint(1) not null,
date datetime not null,
primary key(id)
)engine=MyISAM default charset=GB2312;
insert into member(id,no,name,age,level,sex,date)values
(1,'A001','wanxia',30,'hj',1,'2008-04-02 00:00:00'),
(2,'C022','liyan',29,'zs',1,'2007-05-31 00:00:00'),
(3,'A006','zhangyan',36,'hj',1,'2007-06-20 00:00:00'),
(4,'B052','luanying',42,'bj',1,'2007-02-12 00:00:00'),
(5,'A007','duxiang',26,'hj',2,'2008-03-26 00:00:00'),
(6,'C060','liuyu',38,'zs',1,'2008-10-16 00:00:00');

2 读取数据
2.1 建立01.php
代码

代码如下:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=GB2312"/>
<title>会员列表</title>
</head>
<?php
$link=mysql_connect("localhost","root","123"); //连接mysql服务器
$db=mysql_select_db("club"); //选择数据库
mysql_query("set names utf8",$link); //设定编码方式
$sql="Select * from member";
$result=mysql_query($sql,$link); //执行select查询
$num=mysql_num_rows($result); //获取记录查询
?>
<body>
<h1>健身俱乐部会员名册</h1>
<br />
点击姓名可查看该会员详细资料，现有会员<?php echo $num ?>人。
<br />
<?php
if($num>0)
{
?>
<table border="1" cellpadding="1" cellspacing="1">
<tr>
<td>序号</td>
<td>姓名</td>
<td>性别</td>
</tr>
<?php
while($row=mysql_fetch_array($result))
{
echo "<tr><td>".$row['id']."</td><td><a href=member.php?name="
.$row['name'].">".$row['name']."</a></td><td>"
.($row['sex']==1?"女":"男")."</td></tr>";
}
?>
</table>
<?php
}
else
{
echo "俱乐部尚未发展会员。";
}
?>
</body>
</html>

2.2 建立member.php

代码如下:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=GB2312"/>
<title>会员详细资料</title>
</head>
<?php
$link=mysql_connect("localhost","root","123"); //连接mysql服务器
$db=mysql_select_db("club"); //选择数据库
mysql_query("set names utf8",$link); //设定编码方式
$sql="select no,name,sex,age,level,date_format(date,'%Y-%c-%d') as join_date from member "
."where name='".trim($_GET['name'])."'";
$result=mysql_query($sql,$link); //执行在select查询
?>
<body>
<h1>健身俱乐部会员详细资料</h1>
<?php
if($row=mysql_fetch_array($result))
{
echo "编号：".$row['no']."<br />";
echo "姓名：".$row['name']."<br />";
echo "性别：".($row['sex']==1?"女":"男")."<br />";
echo "年龄：".$row['age']."<br />";
echo "级别：".$row['level']."<br />";
echo "加入：".$row['join_date']."<br />";
}
?>
</body>
</html>

3 修改数据
3.1 建立level.php（修改数据）

代码如下:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=GB2312" />
<title>俱乐部优惠活动</title>
</head>
<body>
<h1>俱乐部会员统计表</h1>
<?php
$link=mysql_connect("localhost","root","123"); //连接mysql服务器
$db=mysql_select_db("club"); //选择数据库
mysql_query("set name utf8",$link); //设定编码方式
$sql="Select level,count(*) as num from member group by level";
$result=mysql_query($sql,$link); //执行select查询
while($row=mysql_fetch_array($result))
{
switch($row['level']){
case 'bj':
echo "等级：白金会员     人数：".$row['num']."<br />";
break;
case 'hj':
echo "等级：黄金会员     人数：".$row['num']."<br />";
break;
default:
echo "等级：钻石会员     人数：".$row['num']."<br />";
}
}
?>
<form action="up_level.php" name="level" method="post">
会员优惠升级：从
<select name="old_level">
<option value="hj">黄金会员</option>
<option value="bj">白金会员</option>
</select>
升级至
<select name="new_level">
<option value="bj">白金会员</option>
<option value="zs">钻石会员</option>
</select>
<input type="submit" value="确定"/>
</form>
</body>
</html>

3.2 建立up_level.php

代码如下:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=GB2312" />
<title>俱乐部优惠活动</title>
</head>
<body>
<?php
$link=mysql_connect("localhost","root","123"); //连接mysql服务器
$db=mysql_select_db("club"); //选择数据库
mysql_query("set name utf8",$link); //设定编码方式
$sql="update member set level='".trim($_POST['new_level'])
."' where level='".trim($_POST['old_level'])."'";
$result=mysql_query($sql,$link); //执行select查询
echo mysql_affected_rows($link)."人从";
switch(trim($_POST['old_level'])){
case 'bj':
echo " 白金会员 " ;
break;
case 'hj':
echo " 黄金会员 ";
break;
default:
echo " 钻石会员 ";
}
echo "成功升级到";
switch(trim($_POST['new_level'])){
case 'bj':
echo " 白金会员 " ;
break;
case 'hj':
echo " 黄金会员 ";
break;
default:
echo " 钻石会员 ";
}
?>
</body>
</html>
