Thanks for sharing this! Will this help me (or someone like me) manage something like 1 database server (with multiple databases in it) shared between all my projects and then let me swap out the PHP version on a per-project basis? ...basically my qualm with something like XAMPP is that it's hard to swap out the PHP version, and I end up having multiple XAMPP installs for all my different PHP versions I have to work with.

Yes absolutely. I'd suggest creating a "Shared services" stack, and put a MySQL service in that rack. Give it a static port (eg 3306).

Then create a second stack with Nginx or Apache (or both), and your choice of PHPs, as many as you need. All the sites will have access to MySQL from the first stack, on the port you configured (eg 3306).

Alternatively, do the "shared services" stack then add one stack per project. Just depends how you like to organise it.
