The purpose of this application is to demonstrate PHP 8.x capabilities as well as writing testable, maintainable code.

The task is to create a small command-line utility to help a fictional company determine the dates on which they need to pay salaries to their Sales Department. The company handles their Sales payroll in the following way:

• Sales staff get a regular fixed base monthly salary, plus a monthly bonus
• The base salaries are paid on the last day of the month, unless that day is a Saturday, a Sunday (weekend). In that case, salaries are paid before the weekend. For the sake of this application, ignore public holidays.
• On the 15th of every month bonuses are paid for the previous month, unless that day is a weekend. In that case, they are paid the first Wednesday after the 15th

The filename of the exported data must be provided by the user.

The output of the utility should be a CSV file, containing the payment dates for the next twelve months. The CSV file should contain a column for the month name, a column that contains the salary payment date for that month, and a column that contains the bonus payment date.

The application is built with the Symfony Console component. But the domain models are decoupled from the framework entirely. Apart from the framework these Symfony components are used (but any other 3rd-party code could have been used which provides similar functionality):

• symfony/filesystem
• symfony/clock

Run composer install.

Run vendor/bin/phpunit.

Run bin/console app:payroll-export <filename>.
