Ok, now I ask the user for the database and his password. What I did is to insert temporarily the selected database and the user password in a table. Then writeconf.php erases the data.
Once is finished I would like to send you the script so you can tell me what you think and comment the code so I can improve it. I would really appreciate it.
I have work to do yet though. I'm searching for info on how to use the "mysqlimport" command so I can import the "nuke.sql" to populate the database.
