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['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'); */
Then there is the registration verification:
<?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); }*/
Graduation operation and adding history verification:
<?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');
Any keyword query:
<?php session_start(); $search=$_POST['search']; unset($_SESSION['search']); /*echo '<pre class="code">'; var_dump($_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");
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='#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>
Update data page and verification:
<!DOCTYPE HTML> <!-- 使用HTML5规范,省略多余部分 --> <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'&&$action==''){ ?> <table width="100%" border="0" cellpadding="3" cellspacing="1" class="css_table" bgcolor='#E1E1E1'> <tr class="css_menu"> <td colspan="3"> <table width="100%" border="0" cellpadding="4" cellspacing="0" class="css_main_table"> <tr> <td class="css_main">注意</td> </tr> </table> </td> </tr> <tr> <td class="css_col11"><strong><font color=#50691B>一旦确定不可更改</font></strong></td> </tr> </table> <?php }else if ($action == 'change') {?> </div> <?php }else if ($action == 'enchange') { # code... echo "<h1 id="已经改变">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");
Some front-end design:
<!DOCTYPE HTML> <!-- 使用HTML5规范 --> <html> <head> <title>main</title> <link href="file/Style.Css" rel="stylesheet" type="text/css" /> </head> <body> <?php session_start(); ?> <?php $user = isset($_SESSION['user'])?$_SESSION['user']:""; ?> <?php if($user == "") { // header("location:Login.php"); die("<script> if(typeof(parent) != 'undefined'){ parent.window.location = 'Login.php'; }else{ window.location.href = 'Login.php'; } </script>"); } ?> <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>欢迎<?php echo "$user";?></td> </tr> </table> </td> </tr> <tr> <td class="css_col11"><strong><font color = "#0000FF">登录cookie有效时间为1200秒</strong></td> </tr> </table> <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">联系方式</td> </tr> </table> </td> </tr> <tr> <td class="css_col11"><strong><font color=#50691B>Blog:http://blog.csdn.net/p641290710</font></strong></td> <td class="css_col11"><strong><font color=#50691B>Email:pengjunweiright@163.com</font></strong></td> </tr> </table> <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>Github</td> </tr> </table> </td> </tr> <tr> <td class="css_col11"><strong><font color=#50691B>点击进入本人Github</font></strong></td> </tr> </table> </body> </html>

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
