我是一名 Php 新手，最近收到了一些应用程序 (php/laravel) 的工作，该应用程序在服务器 (AWS) 上运行，使用 MySQL 和 RDS，并由 nginx 托管 app/php 内容
这是定义在 /etc/nginx/conf.d 中找到的 nginx 路径的文件

我有源代码，但之前的自由职业者已停止与客户合作。我没有数据库凭据，我需要访问数据库，但我不能。我尝试从 php 文件中查找密码，我所能找到的只是一个配置文件夹，其中包含一个文件database.php，其内容如下：

我已经使用 printenv 检查了环境变量，但找不到任何 DB_USERNAME 等环境变量。由于应用程序运行良好，因此它能够连接到数据库。
如何获取数据库的凭据。有什么方法可以弄清楚应用程序如何连接到数据库并运行良好？
在 laravel 根目录中，您应该看到一个名为“.env”的文件，打开此文件，您应该在其中看到所有 laravel 实例变量
这是一个 PHP/Laravel 应用程序，连接信息存储在服务器环境中。数据库连接逻辑是框架的一部分，你不必摆弄它（它是第三方代码，不是业务逻辑的一部分）
在某些情况下，环境存储在名为
.env的文件中（位于 PHP 应用程序的根文件夹中）在某些设置中，环境可能不在文件中，但它是在部署期间创建的，并与系统环境变量一起存储。
无论哪种方式，您都应该查找 DB_* 环境变量来获取数据库连接凭据、服务器和端口。
