MySQL Error - help please

I get this error:

My config file:

<?
//Database connection info
$hostname = "localhost";
$username = "username";
$password = "password";
$dbName = "dbname"; 
MYSQL_CONNECT($hostname, $username, $password) OR DIE("Unable to connect to database"); 
@mysql_select_db( "$dbName") or die( "Unable to select database"); 

?>

PHP:

Server runs PHP version 4.3.11 and MySQL 5.0

 

Wrong username and/or password? You could try and replace "localhost" with "127.0.0.1", i've had issues with that a couple of times.

 

It's unable to connect to the mysql socket which most likely means MySQL is not even running.

 

which one of the two functions is causing the error? they both output the same.
Maybe you just entered a wrong database name.

BTW: you don't have to wrap the $dbName in quotes, it's allready a string.

 

it seem that you entered wrong hostname
