    1. Ensure the database ‘inventory_system’ exists and is spelled correctly. Double-check the database connection.
      If you don’t have database set for this project then,

      1. Create a new database named ‘inventory_system’ from phpMyAdmin.
      2. Import the provided database file into this newly created database.
      This will resolve the ‘Unknown database’ error that you’re facing.
