PHP 学生管理系统实现

最近学校开了PHP课程，顺便写了个作业，分享一下吧。。。
　　
　　都是很简单的东西，新手用得着、、、
　　省略部分前端代码、、、
　　首先是登录的校验：

<?php
session_start();
$user = $_POST['userName'];
$pass = $_POST['passWord'];
$_SESSION['user'] = $user;
/*$Enter = $_POST['Login_undo'];
管理员登录的校验*/
$flag = false;
if($user == "Admin"&& $pass == "root")
{
setcookie("userName",$user,time()+1200);
setcookie("userName",$pass,time()+1200);
$flag = true;
header('location:adminPage.php?user=' . $user);
}
else
header('location:Login.php?login=relog');
/*
// 学生登录免校验
if($Enter)
header('location:StuPage.php');
*/

　　然后是注册的校验：

<?php
session_start();
$s_ID = $_POST['s_ID'];
$Name = $_POST['Name'];
$IDcard = $_POST['IDcard'];
$Major = $_POST['Major'];
$sex = $_POST['sex'];
$_SESSION['student'][$s_ID]['s_ID'] = $s_ID;
$_SESSION['student'][$s_ID]['Name'] = $Name;
$_SESSION['student'][$s_ID]['IDcard'] = $IDcard;
$_SESSION['student'][$s_ID]['Major'] = $Major;
$_SESSION['student'][$s_ID]['sex'] = $sex;
header('location:tisi.html');
/*foreach($_SESSION['student'] as $v)
{
if($v == $s_ID)
{
header("location:stu_reg.php?action=look&msg=更新&user=employee&empno=" . $empno . "&idcard=" . $idcard);
}
else
header("location:stu_reg.php?action=look&msg=增加&user=employee&empno=" . $empno . "&idcard=" . $idcard);
}*/
　　毕业操作及加入历史校验：

<?php
session_start();
$s_ID=$_GET['s_ID'];

$_SESSION['history'][$s_ID]['s_ID']=$s_ID;
$_SESSION['history'][$s_ID]['Name']=$_SESSION['student'][$s_ID]['Name'];
$_SESSION['history'][$s_ID]['IDcard']=$_SESSION['student'][$s_ID]['IDcard'];
$_SESSION['history'][$s_ID]['sex']=$_SESSION['student'][$s_ID]['sex'];
$_SESSION['history'][$s_ID]['Major']=$_SESSION['student'][$s_ID]['Major'];
unset($_SESSION['student'][$s_ID]);
header('location:graduate.php?user=Admin&action=delete');
　　任意关键词查询：

<?php
session_start();
$search=$_POST['search'];
unset($_SESSION['search']);
/*echo '<pre>';
var_dump($_POST['search']);
return ;*/
foreach ($_SESSION['student'] as $k1 => $value) {
# code...
if($search==$_SESSION['student'][$k1]['s_ID']||$search==$_SESSION['student'][$k1]['IDcard']||$search==$_SESSION['student'][$k1]['Name']||$search==$_SESSION['student'][$k1]['sex']||$search==$_SESSION['student'][$k1]['Major']){
$i = 1;
$stu = $_SESSION['student'][$k1]['s_ID'];
$_SESSION['search'][$stu] = $stu;
}
}
if(isset($i))
header("location:stu_Query.php?user=Admin&action=search");
else
header("location:stu_Query.php?user=Admin&action=q_error");
　　遍历学生信息：

<!DOCTYPE HTML>
<html>
<head>
<link href="file/Style.Css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="100%" border="0" cellpadding="1" cellspacing="1" class="css_table" bgcolor='#E1E1E1'>
<?php
session_start();
$user = isset($_SESSION['user'])?$_SESSION['user']:'';
if($user =='Admin'){
if(isset($_SESSION['student'])){
foreach($_SESSION['student'] as $k1) {
echo "<tr>";
foreach($k1 as $k2=>$k3) {
echo "<td>" ;
if($k2=='s_ID') {echo "学号:" ;} else if($k2=='IDcard'){echo "身份证号:";}else if($k2=='sex'){echo "性别:";}else if($k2=='Name'){echo "姓名:";}else if($k2 =='Major'){echo "专业:";};
echo "</td>";
echo "<td>";
if($k2=='s_ID') $s_ID=$k3; echo "$k3";
echo "</td>";
}
}
}
}
?>
</table>
</body>
</html>
　　更新数据的页面及校验：

<!DOCTYPE HTML>

<html>
<head>
<?php
session_start();
$user = isset($_SESSION['user'])?$_SESSION['user']:'';
$action = isset($_GET['action'])?$_GET['action']:'';
?>
<link href="file/Style.Css" rel="stylesheet" type="text/css" />
</head>
<body>
<?php if($user =='Admin'&&$action==''){ ?>
<table width="100%" border="0" cellpadding="3" cellspacing="1" class="css_table" bgcolor='#E1E1E1'>
<tr class="css_menu">
<td colspan="3">
<table width="100%" border="0" cellpadding="4" cellspacing="0" class="css_main_table">
<tr>
<td class="css_main">注意</td>
</tr>
</table>
</td>
</tr>
<tr>
<td class="css_col11"><strong><font color=#50691B>一旦确定不可更改</font></strong></td>
</tr>
<form name = "check_stu" method="post" action="check_stu.php">
<td><lable>请输入修改学生的学号:
<input name = "c_ID" type="text" >
<input name = "submit" type="submit" value="确定">
</lable></td>
</form>
</table>
<?php }else if ($action == 'change') {?>
<form name="login_f" method="post" action="update_check.php">
<div class = "login" align="center">
<lable>可以修改的项目：</lable>
<input name = "c_ID" type="hidden" value = "<?php echo $_GET['c_ID'];?>">
<li><p>学生姓名：
<input name = "Name" type = "text" id = "Name"></p></li>
<li><p>专业：    
<input name = "Major" type = "text" id = "Major"></p></li>
<li>
<p>性别：          

<input type="radio" name="sex" value="男"/>男    
<input type="radio" name="sex" value="女"/>女     </br>
</li>
<li><p>确定修改：      
<input name = "submit" type = "submit" value = "确定" >    
<input class="Renew" value="重写" type="reset" />  </p></li>
</form>
</div>
<?php }else if ($action == 'enchange') {
# code...
echo "<h1>已经改变</h1>";
}?>
</body>
</html>

<?php
session_start();
$s_ID = $_POST['c_ID'];
$Name = $_POST['Name'];
$Major = $_POST['Major'];
$sex = $_POST['sex'];
$_SESSION['student'][$s_ID]['s_ID'] = $s_ID;
$_SESSION['student'][$s_ID]['Name'] = $Name;
$_SESSION['student'][$s_ID]['Major'] = $Major;
$_SESSION['student'][$s_ID]['sex'] = $sex;
header("location:stu_Update.php?action=enchange");
