Fatal Connect to database error - need help

[Fran Filippelli]

I am new to MYSQL and are having a connect issue: Here is my error:

Fatal error: Call to undefined function mysql_connect() in D:\websites\display999.php on line 23

I am using PHP 5.04 MYSQL 4.1.11 and IIS on a windows XP pro PC.

This same code works on a linux box... but not here..?

here is some of the code:

<?php
//set variables for database:
$host = "localhost";
$user = "root";
$password = "franf";
$dbname = "vzw999";
$tablename = "main";

print $host;
echo $user;
echo $password;
echo $dbname;
echo $conn;

$conn = mysql_connect($host, $user, $password);

mysql_select_db(dbname);
$Query = "SELECT * from $tablename";
$Result = mysql_db_query ($dbname, $Query, $conn);


Thanks
Fran
