はじめに
Elastic BeanstalkでPHPで7.2を起動したところ、おかしい現象がおきたのでメモしておきます。
Elastic Beanstalkを起動すると、下記の画面が確認できます。
サーバにSSHでログインして、PHPのバージョンを確認します。

サーバにログインして、 /var/log/eb-activity.log を確認するのが通常です。
いろいろと調べて２〜３日かかったので、調査の結果でわかった点について書いていきます。

結論
他のアプリをデプロイすると、PHPのシンボリックリンクが変わらなかったので、業務で使ってるアプリケーションだとおかしくなっていました。一体どこが影響してるのか現在も調査中です。
おまけ
同じ様な現象があったようだ。ナカーマ。
