我有以下的代码编写，找不到在PHP类
<?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，它给我的错误：
Fatal error: Class 'MX_Controller' not found in C:\xampp\htdocs\pro\application\modules\products\controllers\products.php on line 10
现在没有理由不应该在那里找到类。

'类延伸产品MX_Controller'凡'MX_Controller'设置？您可能也需要包含该文件。 –
@Rocket：我的想法一样，但你看到'products.php'文件本身并没有包括它，但它工作得很好。 –
你在说什么？ 'products.php'不能“正常工作”。 “致命错误：在** products.php **中找不到类'MX_Controller'”。 –
