MySql Connection

[qua doc]

Hi, I'm new to MySql. For example, my MySQL have the following informations

DB Name: MyTest
Server IP: 99.99.999.999.99
Login ID: mylogin
Db Type: mySQLDB
password = mypasswd

Could someone shows me how to set the parameters for the following statement? What do I use for host, user and passwd?

$dbc = mysql_connect ($host, $user, passwd$);
