Code: Select all

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
part .. i dont have in my game and it works XD

You need to always use a DocType of some kind. Otherwise some browsers will be triggered to go into "quirks mode" where it will render like old < IE 5 browsers. You really, really don't want that to happen!

The error has nothing to do with your Doctype. The error means you are outputting html before PHP is done processing the pages/scripts. Basically, consider PHP a toilet hihi. When you are not done doing what ever you need to do, you don`t flush. Right? Well, that`s the same with PHP. If PHP is not ready, don`t start the flush. If you are already outputting HTML ( beginning the flush) PHP doesn`t know what to do. So the error is triggered.

You can circumvent this by using an output buffer.

On the top of the script you can use this:

ob_start();

And at the end of the script, you still need to flush, so:

ob_flush();

Or ob_end_clean();

No, the error has nothing to do with the DocType. Vitinho just suggested not to use one, which is not a good idea.
