Subject: Re: Bug? Raw POST data in PHP 5.2.2, take two
From: unknown@simplemachines.org ("Unknown W. Brackets")

It sounds like you have register_globals off, which is a good thing imho.

You are trying $HTTP_RAW_POST_DATA but my recollection tells me it is 
$_SERVER['HTTP_RAW_POST_DATA'].  Does the latter work?

Anyway, reading from php://input is more correct and doesn't depend on 
PHP settings as much, as far as I know.
