I have a mysql database that I currently access with a php file, in the following setup:

[my site’s current url]/php/scores.php

Within the php file, I connect to the database through ‘localhost’.

The problem is, I’d like to start hosting more than one domain on my droplet. I read about implementing virtual hosts. That’s fine, and I can move my php files to match up to the new url subdirectories in the virtual host root folder.

However, the php files access the mysql database through 'localhost’. Once I setup virtual hosts, will that need to change? Or is mysql 'localhost’ location independent of any virtual hosting setup?

Thanks!
