我想在我的“Adaptive_paypal_model”中扩展 Paypal_class_model。当我写

   class Adaptive_paypal_model extends Paypal_class_model
   {

此代码显示错误消息：

 Fatal error: Class 'Paypal_class_model' not found in C:\xampp\htdocs\business1\application\models\adaptive_paypal_model.php on line 3

请帮我

这是我要包含的代码。请告诉我在 php 中包含文件的另一种方法

         class Paypal_class_model extends CI_Model
      {


     function Paypal_class_model()
         {

 $SSL = '';


function __construct($DataArray)

    if(isset($DataArray['Sandbox']))
    {

    }

    else

    }

您可以只自动加载模型，但可以在此处找到更好的解决方案：在 Codeigniter 2 中扩展多个模型 您可以节省每次调用中自动加载的开销。
