mySQL connection string

[rich hemmings]

Hi Guys Im creating my own website and I have never connected via SQL before only bu using MS Access.

I'm using Heart Internet and Joomla (I'm hard coding this as I'm looking for my first graduate job)I take it with the variables I have to define where my site is, what the name of the website is and the user name and password of the backend of the SQL database?

<?php # Script 7.2 - mysql_connect.php

// This file contains the database access information.
// This file also establishes a connection to MySQL and selects the database.

// Set the database access information as constants.
DEFINE ('DB_USER', 'username');
DEFINE ('DB_PASSWORD', 'password');
DEFINE ('DB_HOST', 'localhost');
DEFINE ('DB_NAME', 'sitename');

// Make the connnection.
$dbc = @mysql_connect (DB_HOST, DB_USER, DB_PASSWORD) OR die ('Could not connect to MySQL: ' . mysql_error() );

// Select the database.
@mysql_select_db (DB_NAME) OR die ('Could not select the database: ' . mysql_error() );
?>
