Stuck with empty $postData = file_get_contents('php://input');

[Igor Donin]

Hi, all!

It's been a whole day now and I'm stuck with getting empty results from $postData = file_get_contents('php://input');

My environment is PHP 5.3.3, Apache 2.2.6, localhost.

If anyone can point me in the right direction, it'll be much appreciated.
