Description:
------------
When i used register_shutdown_function and file_get_contents('php://input').
It will trigger error message:
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

But i did not used $HTTP_RAW_POST_DATA!!!

Test script:
---------------
<?php
function test()
{
    if($e = error_get_last())
        var_dump($e);
}
register_shutdown_function('test');

var_export(file_get_contents('php://input'));exit;
