In OSS, the basic unit of data is a file, which is called an object. The OSS PHP software development kit (SDK) provides multiple ways to upload files:
Simple upload (PHP SDK V1): Files cannot exceed 5 GB.
Append upload (PHP SDK V1): Files cannot exceed 5 GB.
Multipart upload (PHP SDK V1): The maximum file size is 48.8 TB. Use multipart upload for large files.
Note
For more information about the scenarios for each upload method, see Upload files in the Developer Guide. After the upload is complete, you can also configure an upload callback (PHP SDK V1).
