如何使用PHP和进度条将文件直接上传到S3

Question

There are some similar questions but none have a good answers in how to upload files directly to S3 using PHP with progress bar. Is it even possible adding a progress bar without using Flash?

NOTE: I am referring to uploading from client browser directly to S3.

Answer 1

Technically speaking, with PHP you cannot go from client --> S3. Your solution, if you want to use PHP would either have to be designed as follows:

• Client -> Web Server (PHP) -> Amazon S3
• Client with PHP server embedded -> Amazon S3

The AWS PHP SDK: http://aws.amazon.com/sdkforphp/ is very well written and contains a specific example on how to send a file from a Client --> Server --> S3

With respects to the progress bar, there are many options available. A quick search of stackoverflow.com shows a question answered identical to this one:

• Upload File Directly to S3 with Progress Bar
• 'pass through' php upload to amazon's s3?
