problem connecting to mysql server via php

[JASONE25]

Hi every body. I got an php scrip that supposed to connect to mysql sever. The connection string was like this one

$this->connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS)

since i am runing mysql server on local server i did not put any pass for it and i tried to connect like this :

    $this->connection = mysql_connect(localhost,root) or die(mysql_error());

But unfortuently when i run it. I get the following error:

Notice: Use of undefined constant localhost - assumed 'localhost' in c:\inetpub\[URL unfurl="true"]wwwroot\sources\database.php[/URL] on line 23

Notice: Use of undefined constant root - assumed 'root' in c:\inetpub\[URL unfurl="true"]wwwroot\sources\database.php[/URL] on line 23
Unknown database 'insert your database details here'

i be happy if some one help me fix this problem.Thanks

Should they not be strings - 'localhost' and 'root' or $localhost and $root? You'll probably want a password too.
