I'm developing a game where I'd like to upload stats to a website. I don't care how (it could be a text file with a user's name and score), I'm just wondering how I'd go about doing this.

On the client side, you generate an HTTP POST request with a body in URL form encoding. On the server side, you write a script to accept an HTTP POST and add it to the database. Plenty of games for Java and Flash players do this.

To further explain Tepple's solution...
If you're running a webserver, you could construct a packet to send to a script as such:
| Code: |
POST /path/to/record.php HTTP/1.1
Host: www.yoursite.net
User-Agent: Youragent/Version
Content-Length: [length]
Content-Type: application/x-www-form-urlencoded
username=blah&score=blah&whatever |
Of course, you want to replace the obvious placeholders with something more meaningful. Also remember that you must URL-encode the data.
Your server script would look something like this:
| Code: |
<?PHP
$username = $_POST['username'];
$score = $_POST['score'];
// etc.
// record-to-database
?> |
If you need help on the specifics of the code, find out what kind of stuff available on your web host (MySql, etc.) or give a template as to how the data is to be stored.
When testing your script, rather than testing the HTTP packet on the DS, try and use telnet. Just a hint. ;)
If a script is pre-written, it shouldn't be to hard to fit your HTTP packet to the form.

Oh, I could understand the server half of it, because i'm no novice to PHP and MySQL.
But what do you mean by URL encode?

Write it as you would a URL: blah=foo&lol=bar&omgspace=lol,%20spaces
Of course if you just have it send name and score, anyone will be able to send the same from a web browser and fake scores.

Your code can sign and/or encrypt the message contents, but then anybody can ROM-hack your DS game to use its crypto subroutines.

That's at least more difficult than making your own form in HTML or using a program like netcat.
