EDIT: Looked at your post, 1 letter and so on after is no good later on.
I would say, start of with HTML and CSS, followed by PHP and MySQL if you want to be programming webapplications. Otherwise I would say, Java to start of with and thereafter C++ and C#.
Indeed it's true that you can write code like this:
<?php
if(statement)
echo $var;
else
die();
?>
but thats ONLY when the code is one row, otherwise you gotta open and close it, so for your code to work you should have following code:
Habbo rooms: <select name="cars"...
You should create a database, then take the database name and put it under database. For the prefix it could be anything. With prefix tan_ it will be like this in the database for example: TABLE tan_users
