PHP require() problem

Hi - wonder if anyone can help me. I've got an require() statement in a PHP script to bring in the MySQL database settings like this:

require("admin/news/db.php");

The following settings are in db.php:

$dbhost = "mysql.xcalibre.co.uk";
$dbuser = "username";
$dbpass = "password";
$dbname = "dbname";

(names have been changed to protect the innocent).

When I try and use those variables to connect to the database as below I get an error:

$db = mysql_connect($dbhost, $dbuser, $dbpass);

mysql_select_db($dbname,$db);

However if I hardcode the settings it works fine:

$db = mysql_connect("mysql.xcalibre.co.uk", "username", "password");

mysql_select_db("dbname",$db);

I don't experience this problem on my own local server (PHP 4.2.2), so I'm guessing it must be specific to the PHP version?

Any help would be greatly appreciated.

try include() instead of require(), see what happens, my exp. is that require is a little bit more picky than include

Thanks mate - I just sussed it - I was using the wrong version of my db.php file - all sorted now!
