Making the chunked request to a stock nginx 1.0.13 installation
on Ubuntu yields a "411 Length Required" message, but enabling
the ngx_chunkin module does indeed correctly serve the request
and populate php://input and $HTTP_RAW_POST_DATA.
This was done with both Ubuntu's distribution of
PHP 5.3.6 and the php5.4-201203221530 snapshot.

First of all, the problem is still here with PHP 5.4 and Apache 2.4.1, I
previously made the mistake to precise the content-length in my headers.
So here is what I found. If you send chunked http request but do not send the
content-length (as we should do using HTTP 1.1 protocol) the body part of the
request is empty (php://input returns nothing). This result remains valid for
the following configuration where PHP runs via FastCGI :
PHP 5.3.10 - APACHE 2.4.1
PHP 5.3-201203101230 - APACHE 2.4.1
PHP 5.4 - APACHE 2.4.1
PHP 5.4-201203101230 - APACHE 2.4.1
The same configuration with PHP running as mod_php is fine, the body request is
available through php://input.

Try a snapshot please, 5.3.10 has nothing else but security fixes unrelated to
this issue.

The problem seems to have been resolved with php 5.4.0 and apache 2.4.1. I
can't reproduce it with this configuration and chunked http requests are now
coming through to php now.
I am going to try with php 5.3.10 and apache 2.4.1 and give feedback on where
it goes.

I forgot to mention that this is on a Linux system

Same problem here. Apache 2.2.15 and PHP 5.3.10 running as FastCGI.
POST datas sent with "Transfer-encoding: chunked" are not received as they
should be. The raw request looks like this :
POST receiveChunk.php HTTP/1.1
User-Agent: PECL::HTTP/1.7.2 (PHP/5.3.8)
Host: www.test.fr
Accept: */*
Pragma: no-cache
Connection: keep-alive
Cache-Control: no-cache
Content-Length: 682668
Transfer-Encoding: chunked
Content-Type: text/html; charset=UTF-8
3ff4
(here, the datas)
0
and the request as the receiving script sees it :
User-Agent: PECL::HTTP/1.7.2 (PHP/5.3.8)
Host: www.test.fr
Accept: */*
Pragma: no-cache
Connection: close
Cache-Control: no-cache
As you can see, the request body is empty.
However, this problem does not occur when PHP runs as mod_php under Apache.
Problem confirmed under PHP 5.3.8 and 5.3.9.
I don't know if that is a PHP bug and maybe the developers could confirm or not
that the request body are wrong before it reaches PHP. I think that it appears
to be a mod_fcgid bug and should be reported as one to Apache bug list.
Here are the scripts to reproduce the bug :
sendChunk.php :
<?php
$fileContentToUp = 'ICAgICAgICAgIgICAgIA==';
$header_array = array(
'Pragma' => 'no-cache',
'Connection' => 'keep-alive',
'Cache-Control' => 'no-cache',
'Content-Length' => strlen($fileContentToUp) ,
'Transfer-Encoding' => 'chunked'
);
$options = array(headers => $header_array);
$r = new HttpRequest('receiveChunk.php', HTTP_METH_POST, $options);
$r->setContentType('text/html; charset=UTF-8');
$r->setBody($fileContentToUp);
$result = $r->send();
echo '$r->getRawRequestMessage() => ';
print_r($r->getRawRequestMessage());
echo "\n\n";
echo '$r->send()->getBody() => ';
print_r($r->send()->getBody());
echo "\n\n";
?>
receiveChunk.php :
<?php
$HttpResponse = new HttpResponse();
echo 'http_get_request_header => '."\n";
print_r($HttpResponse->getRequestHeaders());
echo "\n\n";
echo 'http_get_request_body => '."\n";
print_r($HttpResponse->getRequestBody());
echo "\n\n";
?>
Hope that helps.
