如何将文件从 S3 存储桶复制到 PHP（AWS SDK for PHP）中的 S3 存储桶？

Question

How to copy files from S3 bucket to S3 bucket directly in PHP (AWS SDK for PHP)? I'm finding examples for Ruby, ie: https://stackoverflow.com/a/10418427/2899889 But I can not find a single example for php.Also I could not find methods copy_to() or copy_from() in AWS SDK for PHP - the commands used in Ruby examples?

Answer 1

Refer to the AWS Github for Code Examples.

This is the 1st place you should when you want to learn how to perform tasks using the AWS SDK in a supported programming language.

Here are the PHP code examples for Amazon S3:

Answer 2

Here is an function that does file copying, bucket to bucket:

  function s3toS3FileCopy($sourceBucket, $sourceFilePath, $targetBucket, $targetFilePath) {
    $env = getenv();
    $s3 = new S3Client([
      'version' => 'latest',
      'region'  => 'eu-central-1',
      'credentials' => [
        'key'    => $env['S3_ACCESS_KEY'],
        'secret' => $env['S3_SECRET_KEY'],
      ],
    ]);

    $s3->copyObject([
      'Bucket' => $targetBucket,
      'Key' => $targetFilePath,
      'CopySource' => "{$sourceBucket}/{$sourceFilePath}",
    ]);
  }

'credentials' parameter array can be skipped if some other way is used. Also set the region parameter you need. Copying between different regions is not supported. It's simple, but parameters are no so intuitive.
