1. 입력 기능 작성 완료

<?php
define(&#39;THINK_PATH&#39;, &#39;../ThinkPHP&#39;);    //定义ThinkPHP框架路径(相对于入口文件)
define(&#39;APP_NAME&#39;, &#39;App&#39;);       //定义项目名称
define(&#39;APP_PATH&#39;, &#39;./App&#39;);        //定义项目路径
require(THINK_PATH."/ThinkPHP.php");  //加载框架入口文件
App::run();               //实例化一个网站应用实例

class IndexAction extends Action{
  public function index(){
    $db_dsn="mysql://root:root@127.0.0.1:3306/db_database30";    //定义DSN
    $db = new Db();                       //执行类的实例化
    $conn=$db->getInstance($db_dsn);               //连接数据库，返回数据库驱动类
    $select=$conn->query(&#39;select * from think_user&#39;);      //执行查询语句
    $this->assign(&#39;select&#39;,$select);       // 模板变量赋值
    $this->display();              // 指定模板页
