PHP student management system implementation

The school recently opened a PHP course, so I wrote an assignment and would like to share it. . .

These are very simple things that novices can use...,,

Omit some front-end code,,,

The first is the login verification:

<?php 
	session_start();
	
	$user = $_POST[&#39;userName&#39;];
	$pass = $_POST[&#39;passWord&#39;];
	$_SESSION[&#39;user&#39;] = $user;
	/*$Enter = $_POST[&#39;Login_undo&#39;];
	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(&#39;location:adminPage.php?user=&#39; . $user);
	}
	else
		header(&#39;location:Login.php?login=relog&#39;);
	/*
	// 学生登录免校验	
	if($Enter)
	header(&#39;location:StuPage.php&#39;);
	*/

Copy after login

Then there is the registration verification:

<?php
	session_start();
	$s_ID = $_POST[&#39;s_ID&#39;];
	$Name = $_POST[&#39;Name&#39;];
	$IDcard = $_POST[&#39;IDcard&#39;];
	$Major = $_POST[&#39;Major&#39;];
	$sex = $_POST[&#39;sex&#39;];

	$_SESSION[&#39;student&#39;][$s_ID][&#39;s_ID&#39;] = $s_ID;
	$_SESSION[&#39;student&#39;][$s_ID][&#39;Name&#39;] = $Name;
	$_SESSION[&#39;student&#39;][$s_ID][&#39;IDcard&#39;] = $IDcard;
	$_SESSION[&#39;student&#39;][$s_ID][&#39;Major&#39;] = $Major;
	$_SESSION[&#39;student&#39;][$s_ID][&#39;sex&#39;] = $sex;
	header(&#39;location:tisi.html&#39;);
	/*foreach($_SESSION[&#39;student&#39;] 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);
	}*/

Copy after login

Graduation operation and adding history verification:

<?php
	session_start();

	$s_ID=$_GET[&#39;s_ID&#39;];


	$_SESSION[&#39;history&#39;][$s_ID][&#39;s_ID&#39;]=$s_ID;
	$_SESSION[&#39;history&#39;][$s_ID][&#39;Name&#39;]=$_SESSION[&#39;student&#39;][$s_ID][&#39;Name&#39;];
	$_SESSION[&#39;history&#39;][$s_ID][&#39;IDcard&#39;]=$_SESSION[&#39;student&#39;][$s_ID][&#39;IDcard&#39;];
	$_SESSION[&#39;history&#39;][$s_ID][&#39;sex&#39;]=$_SESSION[&#39;student&#39;][$s_ID][&#39;sex&#39;];
	$_SESSION[&#39;history&#39;][$s_ID][&#39;Major&#39;]=$_SESSION[&#39;student&#39;][$s_ID][&#39;Major&#39;];

	unset($_SESSION[&#39;student&#39;][$s_ID]);

	header(&#39;location:graduate.php?user=Admin&action=delete&#39;);

Copy after login

Any keyword query:

<?php
	session_start();
	
	$search=$_POST[&#39;search&#39;];
	unset($_SESSION[&#39;search&#39;]);

	/*echo &#39;<pre class="code">&#39;;
	var_dump($_POST[&#39;search&#39;]);
	return ;*/

	foreach ($_SESSION[&#39;student&#39;] as $k1 => $value) {
		# code...
		if($search==$_SESSION[&#39;student&#39;][$k1][&#39;s_ID&#39;]||$search==$_SESSION[&#39;student&#39;][$k1][&#39;IDcard&#39;]||$search==$_SESSION[&#39;student&#39;][$k1][&#39;Name&#39;]||$search==$_SESSION[&#39;student&#39;][$k1][&#39;sex&#39;]||$search==$_SESSION[&#39;student&#39;][$k1][&#39;Major&#39;]){
			$i = 1;
			$stu = $_SESSION[&#39;student&#39;][$k1][&#39;s_ID&#39;];
			$_SESSION[&#39;search&#39;][$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");

Traverse student information:

<!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=&#39;#E1E1E1&#39;>
<?php
	session_start();
	$user = isset($_SESSION[&#39;user&#39;])?$_SESSION[&#39;user&#39;]:&#39;&#39;;
	if($user ==&#39;Admin&#39;){
		if(isset($_SESSION[&#39;student&#39;])){
			foreach($_SESSION[&#39;student&#39;] as $k1) { 
			echo "<tr>";
		
			foreach($k1 as $k2=>$k3) {
			echo "<td>" ;
			if($k2==&#39;s_ID&#39;) {echo "学号:" ;} else if($k2==&#39;IDcard&#39;){echo "身份证号:";}else if($k2==&#39;sex&#39;){echo "性别:";}else if($k2==&#39;Name&#39;){echo "姓名:";}else if($k2 ==&#39;Major&#39;){echo "专业:";}; 
			echo "</td>";
			echo "<td>";
			if($k2==&#39;s_ID&#39;) $s_ID=$k3;  echo "$k3";

		}
	}

Update data page and verification:
