Use {$var} instead of ${var}

[GOD-oda]

背景

php8.2で${var}による文字列への埋め込みが非推奨になった

php8.2環境で、phpcs-psr4-sniffをインストールしphpcsを実行した結果

メモ:

同じ問題にあたって psr4 の check 方法について調べていました。

composer 2.0 系でサポートされた composer dumpautoload --strict-psr によって
suin/phpcs-psr4-sniff と同様のチェックをできるかも知れません。

https://getcomposer.org/doc/03-cli.md#dump-autoload-dumpautoload

github action 例:

name: COMPOSER-DUMP-AUTOLOAD-STRICT-PSR

on:
  push:
    branches:
      - main
  pull_request:
    types: [synchronize, opened, reopened]
    paths:
      - '**/*.php'

jobs:
  check-psr4-by-composer-dump-autoload-strict-psr:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v2
      - name: Install Dependencies
        uses: docker://composer:2.4.1
        env:
          COMPOSER: composer.json
          COMPOSER_VENDOR_DIR: vendor
        with:
          entrypoint: /usr/bin/composer
          args: install -q --no-ansi --no-interaction --no-scripts --no-suggest --no-progress --prefer-dist
          path: ${{ github.workspace }}
      - name: composer psr4 validate
        uses: docker://composer:2.4.1
        env:
          COMPOSER: composer.json
          COMPOSER_VENDOR_DIR: vendor
        with:
          entrypoint: /usr/bin/composer
          args: dump-autoload --strict-psr
          path: ${{ github.workspace }}

Is there any chance that this is going to get merged? Or has this repository been abandoned?

I tried to port it
This would be included in php-collective/code-sniffer#14

But so far it doesn't seem to work for me at all.. Reports nothing on actual issues.
