<?php

    require "./controller/{$class_name}.php";
});

// 从路由中获取参数
$action = $_GET['a'] ?? "a";
$control = $_GET['c'] ?? "c";
$action = strtolower($action);   // 全部转成小写
$control = ucfirst(strtolower($control));  // 先转成小写，然后将首字母转成大写


$action = $action."Action";
$control = $control."Controller";

// 执行对应的类和方法
$obj = new $control();
