S3 Transfer Manager 接受組態選項來自訂其行為。當您建立 Transfer Manager 執行個體時，請提供這些選項。組態參數可以是陣列或 S3TransferManagerConfig <add link> 的執行個體。

下列範例會設定 S3 Transfer Manager 執行個體：

<?php

use Aws\S3\S3Transfer\S3TransferManager;

require __DIR__ . '/../vendor/autoload.php';

$transferManager = new S3TransferManager(
    null,
    [
        // 10MB parts for multipart operations.
        'target_part_size_bytes' => 10 * 1024 * 1024,

        // Use multipart upload for files larger than 20MB.
        'multipart_upload_threshold_bytes' => 20 * 1024 * 1024,

        // Enable checksum calculation for data integrity.
        'request_checksum_calculation' => 'when_supported',

        // Enable checksum validation when getting objects.
        'response_checksum_validation' => 'when_supported',

        // Use part-based multipart downloads.
        'multipart_download_type' => 'part',

        // Allow up to 10 concurrent operations.
        'concurrency' => 10,

        // Enable progress tracking.
        'track_progress' => true,

        // Set default region for default S3 client construction.
        'default_region' => 'us-west-2',
    ]
);
