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)

  }
 }
 </script>
</head>

 <?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>";
