go into your Control Panel, click on the database link, it should be easy from their

if not:

you'll see a text box and a button together saying 'create databse' so obviously that where you create thge database

it will be simlilar creating the user text box and button, then when their both created an extar option will appea, add user to database, which you must also do

that depends on what you want do, can you elaborate please?

i dont think you can im afraid, all i can input, is if you put the fil;e you want to password protect in a different folder, and password protect it using control panel

if you really need it to be php, post here or PM me and i'll create u a small script that will do it
