Last updated at Posted at 2017-10-17

##下準備

AWS SDK for PHPを下記コマンドでインストール

php composer.phar require aws/aws-sdk-php

##設定

S3Controller

use Aws\S3\S3Client;

public function initialize(array $config)
    {
        $this->config = [
            's3' => [
                'key' => 'key', //S3アクセスのためのキー
                'secret' => 'secret', //S3アクセスのためのシークレットキー
                'bucket' => 'bucket', //S3バケット名
            ]
        ];

        $this->s3 = S3Client::factory([
                    'credentials' => [
                        'key' => $this->config['s3']['key'],
                        'secret' => $this->config['s3']['secret']
                    ],
                    'region' => 'ap-northeast-1', //リージョンは日本
                    'version' => 'latest' //バケットのバージョニングは最新
        ]);
    }


##シンプルなサンプル

ファイルアップロード

$result = $this->s3->putObject([
            'Bucket' => $this->config['s3']['bucket'],
            'Key' => 'test/img.jpg', //アップロード先のフォルダとファイル名を指定
            'SourceFile' => $imgData['tmp_name'],
            'StorageClass' => 'REDUCED_REDUNDANCY' //低冗長化モードを指定
        ]);

リスト取得

//オブジェクト型で取得
$list = $this->s3->listObjects([
         'Bucket' => $this->config['s3']['bucket'],
         'MaxKeys' => 10, //最大取得数
         'Prefix' => 'folder' //フォルダ指定
        ]);

//下記コードでフォルダと画像名のみ取得する
foreach ($list['Contents'] as $img) {
      $result[] = $img['Key'];
}

画像削除

$result = $this->s3->deleteObject([
            'Bucket' => $this->config['s3']['bucket'],
            'Key' => 'test/deleted.jpg']//削除対象を指定
          );

他にも様々な機能があるので、確認して見てください。
