Passing Variables in the URL

[D_tunisia]

I understand the usual way to pass ids in the URL:

http://www.example.com/page.php?id=1

But I've seen some pages that use PHP and look like this:

http://www.example.com/?R54TDD

Is this the same thing or something completely different? If it's different can someone explain how this works and how I can replicate it?

Thanks.

It is the same thing.

In this case, it is only the name that is being used, so $_SERVER['QUERY_STRING'] would be a way to access it.

Thanks! I love you!!!
