Defining variables in a seperate file

I am missing a trick here on how use variables defined in seperate file.

In script 1, I have proved to myself my class is working OK because I can
pass in the values and the echo statement outputs the value of localhost.

<?php
// Script 1
// This script works and outputs the name of localhost
require_once("class.MySQL.php");
$db = new MySQL("localhost", "user", "password", "database");
echo "Name of host: ".$db->host;
?>

However if I assign these values in a seperate file called configuration.php
and put the $variable names in the instantiation statement, it doesn't seem
to work. Can't understand why it doesn't work because I reckon it should
still be passing in the values of $localhost, $user, $password and $database
which is exactly as script 1.

<?php
/* Script 2
This script does not seem assign a value to $localhost
Here is the contents of config.php without the open/close PHP tags.
$host = "localhost";
$user = "user";
$password = "password";
$database = "database"; */

require_once("configuration.php");
require_once("class.MySQL.php");
$db = new MySQL($localhost, $user, $password, $database);
echo "Name of host: ".$db->host;
?>

Appreciate any comments. I am sure I have overlooked something very obvious.

Cheers

Phil

BTW: this is one of the reasons I like to build code with E_NOTICE on: if
would have given me notive $localhost is undefined...

Maybe because you've called it $host not $localhost ??

Yes, typical I've been looking at this for 2 hours and 5 mins after posting
I spot my obvious mistake.

Thanks for taking the trouble.

Just add the following lines to your scripts (or change your php.ini)
while you're developping: (It really does make you write less mistakes)

ini_set('error_reporting', E_ALL);
ini_set('display_errors', TRUE);

Thanks. That is a great tip, I just tried it on the file which I was
originally having problems with and the error message was very useful.

Cheers
