php://input is empty on POST request

Question

Problems with multipart/form-data forced me to parse POST request's parameters manually as I already doing for PUT requests. For that purpose I used this code:

$rawData = file_get_contents('php://input');

But I figured that php://input is always empty for POSTs, at least, for php-fpm SAPI.

Here is some pics from debugger. POST request:

empty $rawData

PUT with same params:

filled $rawData

Is there a way to get raw POST request body? Thanks in advance.

In the meanwhile a pointer to PHP man page why raw data is not available for POST php.net/manual/en/wrappers.php.php — David Riccitelli

RE: the comment above, it IS AVAILABLE for POST request, but it IS NOT AVAILABLE with enctype="multipart/form-data" forms ;) — STT LCU

Correct, that's what we're talking about (see the question). — David Riccitelli

Before PHP 5.4 $HTTP_RAW_POST_DATA is not available with enctype="multipart/form-data" (with the exception of some SAPI implementations), explanations here:

I suggest you give a look to a couple of answers to existing questions:

From PHP 5.4+ you can use the php.ini directive enable_post_data_reading to disable PHP consuming the raw data (hence process it), be aware that $_POST and $_FILES won't be populated though (refer to Vitaly Chirkov answer).

Could you try

var_dump($HTTP_RAW_POST_DATA);

Source:

http://php.net/manual/en/reserved.variables.httprawpostdata.php

=== Edit - this will not show the raw post data for 'multipart/form-data'

That wouldn't work $HTTP_RAW_POST_DATA is not available with enctype="multipart/form-data": php.net/manual/en/…

Looks like: php://input is not available with enctype="multipart/form-data" also php.net/manual/en/wrappers.php
