Unable to connect to MySQL database... what's 'hostname'?

[iceboy]

Hello to all,I have a problem to connect PHP & MySQL together.
I have created a form that gets the username & password from admin and connect him to database.the part of PHP script that connect to mysql is as follow:
[CODE=php]$db=mysql_pconn ect("hostname", $username,$pass word);
if(!$db){
echo"ERROR:conn ecting failed";
exit; }
else
echo"you have connected to database succsessfully"; [/CODE]

I want to know what should i write instead of "hostname" parameter in mysql_pconnect function?
I use IIS as localhost server and DreamWeaver as editor. the path of mysql is :C:/Program Files/MySQL/MySQL Server 6.0/ ,(mysql is not install in root folder of localhost) and TCP Port is 3306.
Can i creat a connection with DreamWeaver directly?

Tanx very much.

Do you need to make a persistent connection to your MySQL database? 99% of the time, the answer is 'no'. Try using mysql_connect instead, and then if you really need a persistent connection (believe me, you'll know if you do!), then change it.

"hostname" is the hostname of the server that runs your MySQL server app. 99% of the time, this will be 'localhost', but you can also use an IP address (w/ or w/o port number) or a domain name if your MySQL server is on a different machine than your web server.
