Object Upload Overview

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

In OBS, objects are basic data units that users can perform operations on. OBS PHP SDK provides abundant APIs for object upload in the following methods:

• Performing a Text-Based Upload
• Performing a Streaming Upload
• Performing a File-Based Upload
• Performing a Multipart Upload
• Performing a Browser-Based Upload

The SDK supports the upload of objects whose size ranges from 0 KB to 5 GB. If a file is smaller than 5 GB, streaming upload and file-based upload are applicable. If the file is larger than 5 GB, multipart upload (whose part size is smaller than 5 GB) is suitable. Browser-based upload supports the file to be uploaded through a browser.

If the uploaded object can be read by anonymous users. After the upload succeeds, anonymous users can access the object data through the object URL. The object URL is in the format of https://bucket name.domain name/directory levels/object name. If the object resides in the root directory of the bucket, its URL does not contain directory levels.
