Je suis nouveau sur Php et on m'a récemment proposé de travailler sur certaines applications (php/laravel) exécutées sur un serveur (AWS) utilisant MySQL et RDS avec nginx hébergeant le contenu app/php

C'est le fichier qui définit le chemin nginx trouvé dans /etc/nginx/conf.d

server {

    server_name mytable.sa;

J'ai le code source mais l'ancien freelance a arrêté de travailler avec le client. Je n'ai pas d'informations d'identification pour la base de données, j'ai besoin d'accéder à la base de données mais je ne peux pas. J'ai essayé de chercher le mot de passe dans le fichier php et tout ce que j'ai pu trouver était un dossier de configuration contenant un fichier database.php avec le contenu suivant :

'connections' => [

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

                    env('DB_HOST_READ'),
                    // env('DB_HOST_WRITE'),
                ],
            ],
            'write' => [
                'host' => [

            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            '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', ''),

J'ai vérifié les variables d'environnement à l'aide de printenv mais je n'ai trouvé aucune variable d'environnement comme DB_USERNAME. L'application fonctionnant correctement, elle peut se connecter à la base de données.

Comment obtenir les informations d'identification de la base de données. Existe-t-il un moyen de comprendre comment l'application se connecte à la base de données et fonctionne correctement ?
