我编写了以下代码，
<?php
require_once "products.php";
$test = new Products;
$array = array(1,2,3,4,5,6,6,7,8,9,10);
$start = 4;
$limit = 9;
$value = $test -> limit($array, $start, $limit);
echo $value;
?>
当我运行它时，它给了我一个错误：
致命错误：找不到类'MX_Controller' C：\ XAMPP \ htdocs中\亲\应用\模块\产品\控制器\ products.php 在第10行
现在没有理由不应该找到那个类。

答案 0 :(得分：3)
class Products extends MX_Controller
表示你的（新）类'Products'扩展了（已经存在的）现有类'MX_Controller'。所以这是Products-class的定义行，不是 MX_Controller。你是否包括MX / Controller.php文件？
答案 1 :(得分：3)
在我看来，你没有将文件包含在MX_Controller类中。
答案 2 :(得分：2)
错误'MX_Controller' not found是因为您的班级（Products）仅扩展 MX_Controller - 请检查代码中的位置。
答案 3 :(得分：1)
要处理extends陷阱，最好使用autoloading。
