WampServer

Hello I want to install forum (php) And I need the name of the database
and the password of the database and the account name of the database
and the service database

thank you

First you will need to greate a database. You can do this by clicking on the wamp icon and the localhost. Go to phpMyadmin on the main page you will see, under mysql, create new data base. Enter any name you want for your database. I would use forum.
Assuming you have not changed the passwords and that you name the database forum here is the info you requested:

name of database: forum
accountname of the database: root
password:
database server: localhost
By default you are running with the username root and no password.
