How to set up your php.ini on Heroku?

Question

PHP

Started with this:

Internal Server Error
Fatal error: 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 php 5.6 there is no support for HTTP_RAW_POST_DATA, it is not used in the code anyway, but PHP asks to do 'always_populate_raw_post_data' to '-1' in php.ini
The site is hosted on Heroku and I have no idea how to configure my php.ini for it.
Installed buildpack, it has php.ini, set 'always_populate_raw_post_data' to '-1' there, still the error does not go away. phpinfo() says always_populate_raw_post_data = 0.
What should I do?
