How to sync a folder with Amazon S3 using aws php sdk?

Question

I not only want to upload files to s3, but also want to remove those deleted files from s3.

For example, I have these 2 files on s3: black.jpg, red.jpg

I have these files in my local directory: black.jpg, green.jpg

I want a function that will upload green.jpg to s3 and delete red.jpg from s3. Is it possible?

Get an array of files with $s3->listObjects(); and a array of local files with readDir();

$uploadList = array_diff($localFiles, $s3Files); // returns green.jpg

$deleteList = array_diff($s3Files, $localFiles); // returns red.jpg

Loop over $uploadList and call $s3->putObject()

Loop over $deleteList and call $s3->deleteObject()

Check out AWS PHP SDK documentation for the necessary method parameters.
