Laravel 中的外部类和 PHP 文件 - 找不到类

Question

我有两个 php 文件，并且我已经创建了一个名为“ExternalClasses”的文件夹并将该文件添加到该文件夹中。在我的 php 文件中，我添加了这一行：

namespace App\ExternalClasses;

在我的控制器中添加这一行：

use App\ExternalClasses\CCheckMail;

这就是我使用它的方式：

$pricesClass = new CCheckMail(); 
$email2 = ['[email protected]']; 
$prices = $pricesClass->execute ($email2); 
return view('pages.home', compact('prices'));

但它给了我一个错误：

Symfony\组件\调试\异常\FatalThrowableError (E_ERROR) 类“App\ExternalClasses\CCheckMail”未找到

这是我的 php 文件（CCheckMail.php）：-
