What do I change the variables to for SQL database

[mmorning16]

I am setting up a football pool and i am using a prebuilt php site. The only insturctions I got were to edited a config.php. I created a database in mysql and created the user account and I uploaded all the files to my public_html folder but I am not sure what I should be changed or what to change it to. Any ideas?

below is what is in the config.php

<?php
//modify vars below
$db_host = 'localhost';
$db_user = 'root';
$db_password = 'connect';
$database = 'nflpickem';
$db_prefix = 'nflp_';
$siteUrl = 'http://localhost/personal/phppickem.com/application/';
$allow_signup = true;
$show_signup_link = true;
$user_names_display = 3; // 1 = real names, 2 = usernames, 3 = usernames w/ real names on hover
//set timezone offset, hours difference between your server's timezone and eastern
define('SERVER_TIMEZONE_OFFSET', 1);

Hi
create a database, create a user and the password.Allow this user full control on the database by adding user to the database.
All this can be done from cPanel and by hitting Mysql database icon
Then
use them here..you need to change those which are put in bold

<?php
//modify vars below
$db_host = 'localhost';
$db_user = 'mmorning_databasename';
$db_password = 'password_that_you_have_set';
$database = 'mmorning_databasename_you_have_set';
$db_prefix = 'nflp_';
$siteUrl = 'folder in which you kept the files -hint- can be found from cPanel ';
$allow_signup = true;
$show_signup_link = true;
$user_names_display = 3; // 1 = real names, 2 = usernames, 3 = usernames w/ real names on hover
//set timezone offset, hours difference between your server's timezone and eastern
define('SERVER_TIMEZONE_OFFSET', 1);

$db_user = 'mmorning_databasename';

is that supposed to be the user name?

$siteUrl = 'folder in which you kept the files -hint- can be found from cPanel ';

I put the files in the Html folder under a phppicks folder, was I supposed to uplaod them some place else? Not sure where I should be looking in the control panel.

BTW THANK YOU for the thelp. I apprciate it.
