Using the Low-Level PHP API for Multipart Upload

Topics

The AWS SDK for PHP exposes a low-level API that closely resembles the Amazon S3 REST API for multipart upload (see Using the REST API for Multipart Upload ). Use the low-level API when you need to pause and resume multipart uploads, vary part sizes during the upload, or do not know the size of the data in advance. Use the high-level API (see Using the High-Level PHP API for Multipart Upload) whenever you don't have these requirements.
