这篇文章主要为大家详细介绍了php学生管理系统的具体实现代码，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了php学生管理系统源码，供大家参考，具体内容如下

功能：
1.添加／删除／修改
2.数据存储.
界面分布：
index.php --->主界面
add.php --->stu添加
action ---> sql中add/del/update (处理html表单-->mysql的数据存储＆＆页面跳转)
edit.php --->stu修改
menu.php -->首页

1. index.php

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>学生信息管理</title>
 <script>
  function doDel(id) {
   if(confirm('确认删除?')) {
    window.location='action.php?action=del&id='+id;
   }
  }
 </script>
</head>
<body>
<center>
 <?php
 include ("menu.php");
 ?>
 <h3>浏览学生信息</h3>
 <table width="500" border="1">
  <tr>
   <th>ID</th>
   <th>姓名</th>
   <th>性别</th>
   <th>年龄</th>
   <th>班级</th>
   <th>操作</th>
  </tr>
  <?php
//  1. 链接数据库
  try{
   $pdo = new PDO("uri:mysqlPdo.ini","root","1");
  }catch (PDOException $e) {
   die('connection failed'.$e->getMessage());
  }
  //2.执行sql
  $sql_select = "select * from stu";
  //3.data 解析
  foreach ( $pdo->query($sql_select) as $row) {
   echo "<tr>";
   echo "<th>{$row['id']} </th>";
   echo "<th>{$row['name']}</th>";
   echo "<th>{$row['sex']} </th>";
   echo "<th>{$row['age']} </th>";
   echo "<th>{$row['classid']}</th>";
   echo "<td>
     <a href='edit.php?id={$row['id']}'>修改</a>
     <a href='javascript:void(0);' onclick='doDel({$row['id']})'>删除</a>

   echo "</tr>";
  }
  ?>
 </table>
