simple, but missing something?

Not sure why I am not able to get this to work, but to make my stuff easier to configure for different environments I am trying to re-code some of my stuff to work with options from an array. $cfg['hostname'] = "www.server.com"; // Server domain or ip address

$cfg['username'] = "username";        // Database user name
$cfg['password'] = "password";        // Database password

$cfg['bugemail'] = "admin@server.com"; The do something like this: function database_connection() { @mysql_connect($cfg[hostname],$cfg[username],$cfg[password]); @mysql_select_database($cfg[database]); } Is there something special I have to do to get variables out of an array for use here? I have used $user = "name"; and called stuff like @mysql_connect($name); and it has worked before, I think I am missing something here. TIA Jas
