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)

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>

 <?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>
