Description:
------------
I have a PHP page where a JSON object is being passed in the raw post data. To get this object, I use file_get_contents("php://input"). I'm getting a warning that in the future, PHP will not support raw streams of input. To get around this issue with the current version, it says I need to update the php.ini file setting for always_populate_raw_post_data. The problem is that the suggested work around is not possible since I do not have access to modify the php.ini file.

Even if I was able to fix this in the php.ini file, I am concerned about the removal of posting raw data to PHP pages in the future.

I would like to turn this warning off in pages that have this problem via ini_set

I also need to be able to continue to post via RAW data to my PHP pages in the future.

Test script:
---------------
// use the post method with raw data (less than 2048 bytes)
// and send to a PHP page with the following code

if($_SERVER['REQUEST_METHOD'] !== 'POST') exit;
if((int) $_SERVER['CONTENT_LENGTH'] > 2048) exit;
$input = file_get_contents("php://input");
$data = json_decode($input);

Expected result:
----------------
No warning message.

Able to receive raw post data.

Actual result:
--------------
Warning is displayed:

Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0
