Description:
------------
Posting to a php script makes the script hang reading from php://input on a server with IIS 6.0 / CGI

Code works fine on Apache both on Linux and Win32.

Code also works as expected, when "text/plain" is used as enctype in the HTML Form.

Maybe related to #38488 ?
Maybe stdin is not opened as binary any longer?

Reproduce code:
---------------
HTML Form:

<html>
<body>
  <form method="POST" action="1.php">
    <input type="hidden" name="test" value="yyyy">
    <input type="submit">
  </form>
</body>
</html>

PHP Code in 1.php:

<?php
   // Read 1 char
   $f = fopen('php://input', 'rb');
   $inpData = fread($f, 1);
   fclose ($f);
   
   echo($inpData);
   echo("Done");
?>



Expected result:
----------------
Expected Output:

tDone

Actual result:
--------------
Constantly loading, CGI timeout after some minutes.

Can't test. Can't access server but by FTP.

The provided example works fine (at least with latest php-5.2 snapshot and FastCGI SAPI).

Bug is still there: PHP 5.2.10, XP Pro, IIS, CGI - C# client (timeout on req.GetResponse(), content type is application/x-www-form-urlencoded).

An example to reproduce the issue was asked. Saying that the bug is still here does not help.
 [2009-09-01 12:18 UTC] arturm at union dot com dot pl 
I am trying to isolate bug. For this moment I noticed that content-type header plays important role. Only problem is with application/x-www-form-urlencoded. When request is text/xml it is OK.
 [2009-09-01 12:57 UTC] arturm at union dot com dot pl 
OK, my test is similar (hangs on submit):

<?php

if($_SERVER["REQUEST_METHOD"] == "POST")
{
header("Content-type: text/xml");
$s = file_get_contents("php://input");
echo <<<EOT
<xml/>
EOT;
}
else
{
	echo <<<EOT
<form method="post" action="">
	<input type="text" value="abc">
	<input type="submit" name="s1" value="Submit">
</form>
EOT;
}
?>

Bug occured on:
1. Windows XP, PHP 5.2.10, IIS 5.1, CGI
2. Windows 2003, PHP 5.2.6, IIS 5.1, CGI
Didn't occured on:
Windows 2008, PHP 5.2.5 (x64), IIS 6, ISAPI

Please try with IIS6 or 7 with fcgi.

Thank you. There is simple way to make workaround. I just reported a bug :-)
