[PHP-BUG] Bug #51592 [NEW]: file_get_contents('php://input') - empty string if called more than once

From:             
Operating system: Windows 7 Pro x64
PHP version:      5.2.13
Package:          cURL related
Bug Type:         Bug
Bug description:file_get_contents('php://input') - empty string if called more than once

Description:
------------
Second and consecutive calls of file_get_contents('php://input') return
empty string if client issued an HTTP command other than 'GET' or 'POST'
(see example code). If 'GET' or 'POST' HTTP command was issued
file_get_contents('php://input') works correctly.

Not sure if this is cURL related bug, maybe some other PHP package is
responsible.

I am using Apache 2.2 and IE8.

Test script:
---------------
#bug_curl.php
$hcurl = curl_init();
curl_setopt($hcurl, CURLOPT_URL, 'http://test/bug.php');
curl_setopt($hcurl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($hcurl, CURLOPT_HTTPHEADER, array('Content-Type:
text/plain'));
curl_setopt($hcurl, CURLOPT_POSTFIELDS, 'some request text');
curl_setopt($hcurl, CURLOPT_CUSTOMREQUEST, 'DELETE');
//curl_setopt($hcurl, CURLOPT_HTTPGET, true); - this works ok
//curl_setopt($hcurl, CURLOPT_POST, true); - this works ok
$out = curl_exec($hcurl);
curl_close($hcurl);
echo '<pre>'.htmlspecialchars($out).'</pre>';

# bug.php
var_dump(file_get_contents('php://input'));
var_dump(file_get_contents('php://input')); // returns empty string if HTTP
command is not 'GET' or POST'
var_dump(apache_request_headers());


Expected result:
----------------
string(17) "some request text"
string(17) "some request text"
array(4) {
  ["Host"]=>
  string(4) "test"
  ["Accept"]=>
  string(3) "*/*"
  ["Content-Type"]=>
  string(10) "text/plain"
  ["Content-Length"]=>
  string(2) "17"
}



Actual result:
--------------
string(17) "some request text"
string(0) ""
array(4) {
  ["Host"]=>
  string(4) "test"
  ["Accept"]=>
  string(3) "*/*"
  ["Content-Type"]=>
  string(10) "text/plain"
  ["Content-Length"]=>
  string(2) "17"
}
