How to configure MySQL in writing

Okay, I’m sorry I’m really new to this stuff. I’m setting up a script on my site for a website directory. Below is the stuff I need to configure.

PHP:
———
$mysqlroot=”"; //MySQL root
$mysqluser=”"; //MySQL user
$mysqlpass=”"; //MySQL password
$mysqldb=”"; //MySQL database
———
I have it all figured out except the first one that is asking for the mysqlroot. I have no idea what this means. Can someone explain in really simple to understand terms? Where do I find this info and what format do I enter it in?

Thanks for the help – sometimes this stuff is just too confusing!:eek:
