A. Index.php: This document includes db.inc.php (in order to connect to the database), and runs the SQL query to extract the data from the database, assign the database results to PHP variables, calculate the contribution and display the results in a table in html.

B. Contribution_function.inc.php. This file will have a function that calculates the employee contribution as: contribution = 2 * $salary/1000 + $month +3 The variable $bdate was sent to the function as a parameter. To get the month, you have to extract it (try using the substr function) from $bdate. Recall that $salary is a PHP variable that is assigned the value of the MySQL attribute salary that you have extracted from the Employee table of the Company database. Recall that you ran that query in the try block. This function should return the contribution to the calling program. You should then be able to display the information by accessing your contribution/index.php file through localhost.
