That does seem strange. I glanced at this page of yours:

> http://zonk.matfyz.cz/php_post_problem

And I saw this:

REQUEST_METHOD => GET

So, why was the request a GET request rather than a POST request? There is
no content nor any entity headers either, so it doesn't seem like this
line (telling us that the request method was GET) is wrong.

However, I also don't see any URL variables, so it doesn't seem like the
HTTP request contained any form data, whether GET or POST.

This looks a bit better. We still have a GET request method, and the query
string has something:

QUERY_STRING => username=zonk&email=zonk&submit=Submit+me%21

However, I can't explain why a print_r($_GET) would not display the
username, email, and submit form variables. Maybe you can try:

echo $username;
echo $_GET['username'];
echo $_POST['username'];
echo $_REQUEST['username'];
echo $_SERVER['QUERY_STRING'];

Hopefully one of this will output something relevant. Otherwise, I suppose
it's possible that there is a bug in the CGI SAPI, unless I'm missing
something.

Hope that helps.

Chris
