AWS S3 SDK for PHP, Uploading to folders inside a bucket

Question

I'm just getting started with the AWS S3 SDK for PHP, I've managed to upload a folder of items from my PC to an s3 bucket using PHP, is there any way to specify a folder inside that bucket, for example, instead of uploading image.jpg to imagebucket, it uploads to the folder called images inside 'imagebucket'.

Answer 1

There is no concept of folders in aws s3. Its just for display purpose used by amazon AWS UI.

Actually it stores filename as key & data as value.

if you store 5 files with different folders, they are not going to create 5 folders.

Answer 2

From the docs:

public function uploadDirectory($directory, $bucket, $keyPrefix = null, array $options = array())

By specifying $keyPrefix, you can cause the uploaded objects to be placed under a virtual folder in the Amazon S3 bucket. For example, if the $bucket name is my-bucket and the $keyPrefix is 'testing/', then your files will be uploaded to my-bucket under the testing/ virtual folder: https://my-bucket.s3.amazonaws.com/testing/filename.txt
