php---sql

// Connect to the database server
$dbcnx = @mysql_connect("localhost","root", "password"); if (!$dbcnx) { echo( "<P>Unable to connect to the " ."database server at this time.</P>" ); exit(); }

I am using a statement like this to connect to my sql server, however, i do not quite understand some general syntax.

localhost= is this going to be the ip of my linux box, or my firewall
password & root = when i do put char's into here do I take away the quotes??

daa...I figured it out.
thanks
