mysqlnd (+ mysqli etc.) - expose the gtid to PHP in the OkPacket

Description

Looks like the gtid is already being parsed, but not exposed in PHP. It would be great to just be able to access it from the OkPacket with something like packet->gtid or packet->state_changes->gtid.

why

I can use it to track what user did what gtid change to with a gtid aware cdc on mysql. This is already working on a nodejs server (using mysql2). From my PHP server, I can only track from my ORM with timestamp + table + primary-key-id instead of gtid.

The other state changes would also be helpful from PHP-land, e.g. database for limiting the number of pools I need to run in a multi-db environment, which i cant implement in PHP at all.

まず、mysqlnd が mysqli を通じて MySQL OkPacket をどのように解析し公開しているかを追跡し、既存のパケット処理と状態変更の処理に焦点を当てます。PHP コードからパケットの GTID にアクセスでき、公開されている場合は要求されたその他の状態変更にもアクセスできれば完了です。GTID 対応の応答を生成する MySQL セットアップで動作を確認してください。
