Laravel – Need help to decipher how the app connects to the database

I’m a Php newbee and I recently received some work for an app (php/laravel) which is running on the server (AWS) using MySQL with RDS with nginx hosting the app/php contents

this is the file that defines paths for nginx found in /etc/nginx/conf.d

server {

    server_name mytable.sa;
    http2_max_field_size 64k;
    http2_max_header_size 512k;
    client_max_body_size 100m;

    index index.php admin.php;

    error_log /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log main;

    location = /favicon.ico {
        access_log off; log_not_found off;
    }
    location = /robots.txt {
        access_log off; log_not_found off;

I have the source code but the previous freelancer has stopped cooperating with the client. I have no db credentials and I need to access database but I can’t. I tried locating the password from the php files and all I could find was a config folder with a file database.php that has contents like this:

'connections' => [

        'sqlite' => [
            'driver' => 'sqlite',
            'database' => env('DB_DATABASE', database_path('database.sqlite')),
            'prefix' => '',
        ],

                    env('DB_HOST_READ'),
                    // env('DB_HOST_WRITE'),

            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],

        'pgsql' => [
            'driver' => 'pgsql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '5432'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'prefix' => '',
            'schema' => 'public',
            'sslmode' => 'prefer',
        ],
        'sqlsrv' => [
            'driver' => 'sqlsrv',

            'database' => 0,
        ],
];

I have checked the environment variables using printenv but i could not find any env variables that are DB_USERNAME etc. Since the app is running fine therefore it is able to connect to the database.

how can I get the credentials for the database. is there a way I can figure out how the app is able to connect to the database and is functioning just fine?

    In the laravel root directory, you should see a file named ‘.env’ open this file, you should see all your laravel instance variables in there

    check the .env file on the application root folder for keys like: DB_USERNAME= and DB_PASSWORD=

    This is a PHP/Laravel application and the connection information is stored in the server environment. The database connection logic is part of the framework, you don’t have to fiddle with it (it’s third-party code, not part of the business logic)

    In some cases, the environment is stored in a file, called .env (it’s in the root folder of the PHP application)

    There could be some setups where the environment is not in the file but it’s created during deployment and stored alongside the system environment variables.

    Either way you should look for the DB_* environment variables to get your DB connection credentials, server and port.
