Brand new to PHP.  Got a couple of questions. 
 
The following code runs on my local machine but not on my host.  On the host
I'm not sure what value to use for the $site variable.  Using the website or
IP address isn't working.  
 
>>
    // connect to the RDBMS
    $db = mysql_connect("$site","$user","$pass") 
        or die_now("<h2>Could not connect to database server</h2><p>Check
passwords and sockets</p>$site,$user,$pass");
 
    // select the database
    mysql_select_db("$database",$db) 
        or die_now("<h2>Could not select database $database</h2><p>Check
database name</p>");
<<
 
 
Also, why does one select the database after logging in with the user/pw?
Does a username span all of my databases or are users under a given
database?  And also, on a typical web host that serves many accounts, am I
sharing a database with other host accounts or do I have my very own MySQL
instance?
 
And lastly, is there a way to connect to MySQL on my host using a client
side tool like MySQL Turbo Manager?  Is the account I'd use the same
account/pw I'd use to FTP files or is it one of the MYSQL usernames?
 
Much thanks
 -Bill
