PHP script that imports values from csv files, makes calculations in a table, and exports to another .csv file

This project involves 3 .php files. 2 files are just simple imports of values from .csv files

The values are inserted in 2 MySQL tables. Calculations are made, and then output to a third MySQL table.

From the data in the third MySQL table, we generate a .csv file.

The calculations involve using variables from the tables, in a way that is similar to how Excel performs calculations.

A strong understanding of calculation order, operator precedence, and use of parentheses is the key to understanding how to make these calculations, and to completing the job successfully.

Skills: PHP, MySQL, Software Architecture, SQL, Mathematics
