indowebit/Ext-PHP — reverse-engineered prompt

Build me a simple PHP web app framework like this old ExtJS admin starter kit. I want it to run locally, have an installer page where I can set the site title and menu title, then let me log in with an admin account and see a main dashboard page.

The app should include a menu manager and user manager so I can create menus, submenus, and control which user groups can see them. I also want a basic sample module that connects to MySQL, with clear places for model, controller, and ExtJS view code so I can copy it to make my own modules later.

Please include the needed config files for the database and UI scripts, a simple start page after login, AJAX handlers for loading menus and modules, and sample SQL I can import with phpMyAdmin. Keep it easy to understand and close to a classic PHP plus ExtJS setup. Look up current docs online if you need to.
