There are two parts to this assignment. The first part is to create a database and some tables which will be appropriate for a home-budgeting application. That portion of the assignment should be completed from the MySQL console command line. The second part of the assignment is to write a PHP script which will display information about the database tables created in the first part and save that information in a file. A complete submission will include both the script - solution07.php - and the text file generated by the script - solution07.txt. * Use the command-line interface to create a new user named "script" for your database. Grant that user all permissions on everything controlled by the DBMS. * Create a database named "homebudget". * Within that database, create two tables: o The first table should be named "estimates". Give it three fields: + VARCHAR of length 10 named "category" + VARCHAR of length 30 named "description" + INT named "budget" o The second table should be named "expenses". Give it three fields: + VARCHAR of length 10 named "category" + DATE named "expenseDate" + INT named "expenditure" * Create a script file named solution07.php. Within that script, connect to your DBMS using the "script" identity. Select the "homebudget" database, then obtain a listing of the tables.
