PHP+MYSQL学生信息管理系统
一、安装phpstudy+Dreamweaver软件并测试
1、安装PHP（已完成）
2、安装Dreamweaver(之前已安装好了)
3、测试并创建了第一个PHP页面，为加强巩固做多了几个练习
二、学生信息管理系统
1、建立pxscj数据库并建立xs表，kc表，cj表和user表（在Mysql-front完成）
2、储存过程
3、登录页面设计（登录用户：root 登录密码：root 与数据库pxscj连接
代码如下：

$Birthday = @$_POST['cssj']; //生日
$tmp_file = @$_FILES["photo"]["tmp_name"]; //文件被上传后在服务端储存的临时文件
$handle = @fopen($tmp_file,'rb'); //打开文件

$s_sql = "select XM, KCS from XS where XM ='$StudentName'"; //查找姓名、已修课程数信息
$s_result = $db->query(iconv('GB2312', 'UTF-8', $s_sql));
/**以下为各学生管理操作按钮的代码*/
//录入功能
if(@$_POST["btn"] == '录入') {
//单击"录入"按钮
if($s_result->rowCount() != 0) //要录入的学生姓名已经存在时提示
echo "";

if($insert_result->rowCount() != 0) {
$_SESSION['StuName'] = $StudentName;
echo "";
}else
echo "";
}
}
//删除功能
if(@$_POST["btn"] == '删除') {
//单击"删除"按钮
if($s_result->rowCount() == 0) //要删除的学生姓名不存在时提示
echo "";
else {
//处理姓名存在的情况
list($XM, $KCS) = $s_result->fetch(PDO::FETCH_NUM);

}
}
//更新功能

5、点击成绩管理，跳转页面
（1）查询功能
（2）录入功能
（3）删除功能（删除林涣淇 数据库应用技术 98分）
全部功能代码如下：
<html>
<head>
<title>成绩管理</title>
</head>
<body bgcolor="#CCCCCC">
<form method="post">
<table>
<tr>
<td>
课程名：
<!-- 以下JS代码是为了保证在页面刷新后，下拉列表中仍然保持着之前的选中项 -->
<script type="text/javascript">
function setCookie(name, value) {
var exp = new Date();
exp.setTime(exp.getTime() + 24 * 60 * 60 * 1000);
document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString();
}
function getCookie(name) {
var regExp = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
var arr = document.cookie.match(regExp);
if(arr == null) {
return null;
}
return unescape(arr[2]);
}
</script>
<select name="kcm" id="select_1" onclick="setCookie('select_1',this.selectedIndex)">
echo "";
require "fun.php";
$kcm_sql = "select distinct KCM from KC"; //查找所有的课程名
$kcm_result = $db->query($kcm_sql);
while(list($KCM) = $kcm_result->fetch(PDO::FETCH_NUM)) {
//输出课程名到下拉框中
$KC = iconv('UTF-8', 'GB2312', $KCM);
echo ">$KC";
}
?>
</select>
<script type="text/javascript">
var selectedIndex = getCookie("select_1");
if(selectedIndex != null) {
document.getElementById("select_1").selectedIndex = selectedIndex;
}
</script>

<td align="left">
<table border=1 width="285">
<tr bgcolor=#CCCCC0>
<td align="center">姓名</td>
<td align="center">成绩</td>
</tr>
include "fun.php";
//单击【查询】按钮
if(@$_POST["btn"] == '查询') {
//单击"查询"按钮
$CourseName = $_POST['kcm'];
$cj_sql = "select XM, CJ from CJ where KCM ='$CourseName'"; //查找该课程对应的成绩单
$cj_result = $db->query(iconv('GB2312', 'UTF-8', $cj_sql));
while(list($XM, $CJ) = $cj_result->fetch(PDO::FETCH_NUM)) {
//获取查询结果集
$Name = iconv('UTF-8', 'GB2312', $XM);
//在表格中显示输出"姓名-成绩"信息
echo "$Name $CJ
三、实验报告心得
刚开始接触这个课程设计，给出的模板我还看不懂，后来慢慢在自己的钻研下，一步一步完成设计报告，虽然只有两个管理模板，但改部分代码有些吃力，甚至有点做到崩溃，一开始数据库没连接好，页面连接不上，再是页面乱码，是因为字符集问题，所以修改了代码中字符集问题，储存过程也出了问题，导致在学生管理页面显示不出姓名和成绩，在同学帮助下发现问题并解决问题。后来有照片录入失败，修改代码，改变照片大小，也完成它的功能。总之，做好一个学生信息管理系统要有耐心和细心，还有很多需要提升自己的能力。
