cPanel PHP Script Installation -- 2

I have a PHP script ready to deploy and simply need it installed and running on my cPanel hosting account. All files are prepared; once we start I will provide the archive together with temporary cPanel credentials. You are free to decide which PHP version and extensions suit the script best and, if the code requires a database, set up MySQL or PostgreSQL accordingly.

My priority is to see the application online, error-free, and accessible from its public URL. Please handle: uploading, permissions, database creation (if applicable), basic hardening, and a quick post-install test so I know everything works. A concise note of the steps you took and any credentials created will complete the job.
