How to create a folder within S3 bucket using PHP

I'm trying to create a folder within an S3 amazon bucket but I'm finding it difficult to find the right documentation to adequately explain what is needed. I have the following code / pseudocode for creating a folder. Can anyone explain or provide a sample of the arguments I need to place within the code

use vendor\aws\S3\S3Client;

$bucket_url = 'https://******/';
$folder_name = $username . '/';

$s3Client = new vendor\aws\S3\S3Client([
'version' => AWS_VERSION,
'region' => AWS_REGION,
'credentials' => [
'key' => AWS_KEY,
'secret' =>AWS_SECRET,

'Bucket' => AWS_BUCKET, // Defines name of Bucket
'Key' => AWS_PATH . $folder_name, //Defines Folder name
'Body' => "",

S3 doesn't have folders beyond the bucket, but objects (files) can have /s (forward slashes) in their name, and there are methods to retrieve based on a prefix that allows you to emulate a directory-list. This means though, that you can't create an empty folder.

So a work around will be put a empty txt file and delete it after wards but the folder structure will stay.

/* function to upload empty test.txt file to subfolders /folder/ on S3 bucketname */
$s3->putObjectFile(‘test.txt’, ‘bucketname’, ‘/folder/test.txt’, S3::ACL_PUBLIC_READ);

/* function to delete empty test.txt file to subfolders /folder/ on S3 bucketname */
$s3->deleteObject(‘bucketname’, ‘/folder/test.txt’);
