Proper development container

Description

It's too difficult to set up a consistent PHP development environment when involving code that needs external servers, like database providers.

I would like an all-in-one Docker container that has all the software necessary to compile PHP with all extensions, and includes database servers that run in the background so I can run tests out of the box. These should be set up with the right credentials and the right environment variables should exist such that the test suite can connect to these databases. All with zero extra configuration, working out of the box.

I often just skip working on database stuff because it's too much of a PITA to set up things. Working on bugfixes is also frustrating because of this. Copying from the GitHub CI configuration is possible but also not a particularly fun experience.

まず、issueで言及されているGitHub CI設定を確認し、テストスイートに必要なPHP拡張機能、データベースサーバー、認証情報、環境変数を特定します。単一のDockerベースの開発環境でPHPをコンパイルし、データベースサービスを実行し、追加の設定なしでデータベーステストを実行できれば完了です。
