nima-sayadi/PHP-pure-Investment-website ? reverse-engineered prompt

Build me a plain PHP investment website for crypto investments and statistics.

I want a simple public homepage, a login and logout flow, a user dashboard, and an admin dashboard where I can manage users, investments, and view basic activity. The site should connect to a MySQL database, show investment and performance data with charts, and include a few sample fund pages so the layout feels complete.

Keep it clean and practical, using vanilla PHP, HTML, CSS, and JavaScript, with no framework. If it helps, add a basic error page, upload or request image support where needed, and make the design responsive enough to use on desktop and mobile. There is also Persian date support in the project, so keep that working if you use dates anywhere.

Please set it up so it feels like a real ready to use starter project, and look up current docs online if you need to.
