For those of you without the HTTP extension, try:
<?php
  $body
= @file_get_contents('php://input');
?>

In case this saves anyone else some frustration, the "Content-Length" header decides what will be returned for "php://input".  If you leave it out while testing, nothing will be returned for "php://input" or $HTTP_RAW_POST_DATA.

For example, if you are trying to test out a custom SOAP server app and you send a request like this without a Content-Length set:

-----
POST /soap_service.php HTTP/1.1
Authorization: Basic abcdefgh
User-Agent: SOAPy McSOAPclient
Host: example.com
Accept: */*
MIME-Version: 1.0
Content-type: text/xml; charset=utf-8

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cat="http://com.soapy/foobar"><soapenv:Header/><soapenv:Body><foo:ManageBar><foo:task id="1"><foo:getBar type="helloworld"/></foo:task></foo:ManageBar></soapenv:Body></soapenv:Envelope>
----

"php://input" will always return and empty string.

If you leave out Content-Length and have no Transfer-Encoding, your request is no longer valid.

RFC261 says at chapter 4.3:
"The presence of a message-body in a request is signaled by the inclusion of a Content-Length or Transfer-Encoding header field in the request's message-headers."

Without those headers, the server has no way of figuring out what the length of the body is. For a response, you could indicate it with a connection close, but obviously if you do that on a request you will never get a response!

So, I assume the PhP behaviour you describe is OK as you cannot expect it to auto-magically repair all sorts of broken requests!

@Tim Trinidad
Reading php://input or using http_get_request_body_stream() must be very similar.
The documentation says:
"This function can not be used after http_get_request_body_stream() if the request method was another than POST."

So it looks very similar to what you describe. The documentation should then read:
"This function can not be used after http_get_request_body_stream() or reading php://input, if the request method was another than POST."

It seems that there is some weird behavior when using http_get_request_body() with fopen('php://input'). Specifically, reading the input with the fopen('php://input') routine before calling http_get_request_body() on a PUT HTTP request.

Here are some examples:

A POST request:
*********************************************************
PUT http://example.com/requestbodytest.php HTTP/1.1
Host: example.com
Keep-Alive: 300
Connection: keep-alive
Content-Type: text/xml
Content-Length: 58

<?xml version="1.0" encoding="utf-8" ?>
<body>test</body>
*********************************************************

with the following script:
*********************************************************
<?php
$body
= '';
$fh   = @fopen('php://input', 'r');
if (
$fh)
{
  while (!
feof($fh))
  {
   
$s = fread($fh, 1024);
    if (
is_string($s))
    {
     
$body .= $s;
    }
  }
 
fclose($fh);
}
print(
"-------------- PHP Input Stream ----------------\n$body\n\n");

$body2 = http_get_request_body();
print(
"---------- http_get_request_body() -------------\n$body2\n\n");

?>
*********************************************************

outputs this:
*********************************************************
-------------- PHP Input Stream ----------------
<?xml version="1.0" encoding="utf-8" ?>
<body>test</body>

---------- http_get_request_body() -------------
<?xml version="1.0" encoding="utf-8" ?>
<body>test</body>
*********************************************************

The same request to the same script using an HTTP PUT request, however, outputs this:
*********************************************************
-------------- PHP Input Stream ----------------
<?xml version="1.0" encoding="utf-8" ?>
<body>test</body>

---------- http_get_request_body() -------------
*********************************************************

It seems a valid workaround is to put a call to http_get_request_body() to cache the body content before an expected read to php://input (i.e. simply calling the function without manually storing the result caches the content for subsequent calls).
