SDK for PHP 3.x

The valid configuration options are as follows:

• acl: (string) ACL to set on the object being upload. Objects are private by default.
• before_complete: (callable) Callback to invoke before the CompleteMultipartUpload operation. The callback should have a function signature like function (Aws\Command $command) {...}.
• before_initiate: (callable) Callback to invoke before the CreateMultipartUpload operation. The callback should have a function signature like function (Aws\Command $command) {...}.
• before_upload: (callable) Callback to invoke before any UploadPart operations. The callback should have a function signature like function (Aws\Command $command) {...}.
• bucket: (string, required) Name of the bucket to which the object is being uploaded, or an S3 access point ARN.
• concurrency: (int, default=int(5)) Maximum number of concurrent UploadPart operations allowed during the multipart upload.
• key: (string, required) Key to use for the object being uploaded.
• params: (array) An array of key/value parameters that will be applied to each of the sub-commands run by the uploader as a base. Auto-calculated options will override these parameters. If you need more granularity over parameters to each sub-command, use the before_* options detailed above to update the commands directly.
• part_size: (int, default=int(5242880)) Part size, in bytes, to use when doing a multipart upload. This must between 5 MB and 5 GB, inclusive.
• prepare_data_source: (callable) Callback to invoke before starting the multipart upload workflow. The callback should have a function signature like function () {...}.
• state: (Aws\Multipart\UploadState) An object that represents the state of the multipart upload and that is used to resume a previous upload. When this option is provided, the bucket, key, and part_size options are ignored.
