What ports need to be open?

I'm using the most current XAMPP. I want to host an online database with PHP/MySQL. What ports need to be open?

If you go to http://localhost/xampp/index.php and click on the Security menu item, scrolling down will find the list of the ports XAMPP uses and some explanations of their use.

There is also a port list here:
