PHP RFC: Add support ofr parsing request body in JSON format

• Version: 0.1
• Date: 2018-10-02
• Author: CHU Zhaowei jhdxr@php.net
• Status: Draft
• First Published at: https://wiki.php.net/rfc/parse_request_body_in_json

Currently PHP only parse request body when the Content-Type is application/x-www-form-urlencoded or multipart/form-data.[1] This RFC proposes to parse request body with Content-Type application/json or text/json.

It's very common for javascript library to send JSON payload now, however, PHP doesn't have built-in support for it. Userland developers have to deserialize it by themselves, which is inconvenient and inefficient. This RFC proposes to reuse the ability from ext/json to deserialize the payload and fill in $_POST.

$_POST will be filled instead of an empty value when Content-Type is application/json or text/json.

Next PHP 7.x

New SAPI_POST_HANDLER_FUNC will be introduced to implement this RFC.

This RFC doesn't introduce any new settings.

Requires a 2/3 majority to pass.

Links to any external patches and tests go here.

If there is no patch, make it clear who will create a patch, or whether a volunteer to help with implementation is needed.

Make it clear if the patch is intended to be the final patch, or is just a prototype.

For changes affecting the core language, you should also provide a patch for the language specification.

After the project is implemented, this section should contain

1. the version(s) it was merged into
2. a link to the git commit(s)
3. a link to the PHP manual entry for the feature
4. a link to the language specification section (if any)
