Save a WordPress site for future reference

Hello there everybody!

I made a web for a client a few months ago, but sadly it’s going out of business, so she asked me to shut down the website.

Before doing that, I was wondering what are the vest ways to “save” the website for myself, to use it as a future reference for my own portfolio (my client is a family member so it’s ok with her).

I know that if I don’t have a hosting with PHP and databases the site won’t work (at least not online), and I’m sure many of you came across this situation before, so I’m here to read some ideas or experiences you had with this kind of issue.

So… what are the options? Help will be very much appreciated!
