Saya baru menggunakan Php dan baru-baru ini telah ditawarkan bekerja pada beberapa aplikasi (php/laravel) yang berjalan pada pelayan (AWS) menggunakan MySQL dan RDS dengan nginx mengehos kandungan aplikasi/php

Ini ialah fail yang mentakrifkan laluan nginx yang terdapat dalam /etc/nginx/conf.d

Saya mempunyai kod sumber tetapi pekerja bebas sebelum ini telah berhenti bekerja dengan pelanggan. Saya tidak mempunyai kelayakan pangkalan data, saya perlu mengakses pangkalan data tetapi saya tidak boleh. Saya cuba mencari kata laluan daripada fail php dan yang saya dapati hanyalah folder konfigurasi yang mengandungi pangkalan data fail.php dengan kandungan berikut:

Saya telah menyemak pembolehubah persekitaran menggunakan printenv tetapi tidak menemui sebarang pembolehubah persekitaran seperti DB_USERNAME. Memandangkan aplikasi berjalan dengan baik, ia dapat menyambung ke pangkalan data.

Bagaimana untuk mendapatkan kelayakan pangkalan data. Adakah terdapat cara untuk mengetahui cara aplikasi menyambung ke pangkalan data dan berjalan dengan baik?
