MySQL Info With Include PHP

Hello,

My problem is that i cant connect with MySQL.

I get This Error
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on '217.18.70.82' (4) in /home/assassin/domains/realdutchserver.nl/public_html/webformysql/bans.php on line 23
Could not connect to database

This is My Code

$db = mysql_connect('$host','$username','$password') or die(mysql_error()); // This connects to the MySQL server
mysql_select_db('$database', $db);

This is the Include i Use

<?php
$host = '217.18.70.82';
$username = 'server5646';
$password = 'password';
$database = 'server5646';
?>

Your database or user is not configured correctly.

Your code is wrong. You are using single quotes around your variables. If you want treated as variables then use double quotes or no quotes at all.
$db = mysql_connect($host,$username,$password) or die(mysql_error()); // This connects to the MySQL server
mysql_select_db($database, $db);
