类中的 PHP 调用类返回错误:500

我很难在另一个班级上新班级.这是一个设置示例:

I'm having a hard time new a class in another class. This is an example of the setup:

index.php

<?php
   include("functions/userFunctions.php");

   $user = new UserFunctions ();
   $user->validate();
?>

UserFunctions.php

UserFunctions.php

<?php
   include("../db/userDB.php");

   class UserFunctions extends UserDB
   {
       public function GetHello(){
          $this->DBHello();
       }
   }
?>

用户数据库.php

<?php
   class UserDB
   {
       public function DBHello(){
          return "Hello"
       }
   }
?>

Chrome 返回:HTTP 错误 500(内部服务器错误):服务器尝试完成请求时遇到了意外情况.

Chrome returns: HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

这怎么行不通?

推荐答案

将此添加到代码顶部

error_reporting(E_ALL);
ini_set("display_errors","On");

正确的 PHP 错误将在您的 PHP.ini 设置

The right PHP errors would be displayed or swtich it on in your PHP.ini settings
