Composerを使ったほうがいいのか？

なぜ？

AWS SDK for PHP 2 を使用して、AWS の使用を迅速に開始します。この SDK は、Amazon S3、Amazon Glacier、DynamoDB、CloudFront など、多くの AWS サービス向けの Ruby クラスを提供するため、コーディングの複雑さが軽減されます。ダウンロード可能な 1 つのパッケージに、AWS PHP ライブラリとドキュメントが含まれます。

インストール方法はいくつかある

AWS SDK for PHP

Zip or Phar

Pear

Composer & Packagist

Zip or Phar

バージョン管理は目視、手動

バグフィックスなど追いかける手間

呼び出しは、ファイルをrequire

Zip or Phar

救い？CUIでの操作が不要

どこでも好きなところに設置OK

だがそれが不幸の原因に!?

Zip or Phar

なにもかもが手動

手漕ぎ!!

バージョン管理OK

でも、依存性解消までは無理

呼び出しは、pearのディレクトリをinclude_pathに設定

いままで本当にありがとう！

Pear

1サーバ=1バージョン

ひとつの環境上で複数アプリを違ったバージョンで運用できない

複数運用しようとZipへ逆戻り…

いままで本当にありがとう！
