php -> mysql connection error

[Evanthes]

Hey guys ive been developing a program on my local machiene thats works great, however now im moving it to our webserver and am having some problems. I've duplicated everything on the server with the exception of the port that mysql runs on. and now i am getting the following error:
Fatal error: Call to undefined function mysql_connect() in C:\Inetpub\wwwroot\cp\opendb.php on line 3

here is my db connection code
[code]
//opendb.php
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die                      ('Error connecting to mysql');
mysql_select_db($dbname);
[/code]

i guess I'm just wondering why the php in the statement isnt being processed and its giving me the mysql error instead of "error connecting to mysql" like it should say in the code.
the server is a 2k server running IIS, if that might have anything to do with it. thanks for your help!

session_start();

$database_host = "";
$database_username = "";
$database_password = "";
$database_name = "";

$connection = mysql_connect($database_host, $database_username, $database_password) or die(mysql_error());
$db = mysql_select_db($database_name, $connection);

No that is not the problem at all. Its because your PHP set-up doesn't have the MySQL extension enabled. Please read this [url=http://www.phpfreaks.com/forums/index.php/topic,95378.0.html]This FAQ[/url] to enable the MySQL extension.
