Connect To Database

I find it’s always useful to keep this functionality in a function. This example relies on some global variables …pretty easy to understand.

<?php
function connect_to_database(){
	global $DB_HOST,$DB_USERNAME,$DB_PASSWORD,$DB_DATABASE;
	$link = mysql_connect($DB_HOST, $DB_USERNAME, $DB_PASSWORD);
	if (!$link) {
	    die('Not connected : ' . mysql_error());
	}
	$db_selected = mysql_select_db($DB_DATABASE, $link);
	if (!$db_selected) {
	    die ('Can't find/use database : ' . mysql_error());
	}
}
?>
