Update / overwrite acl for file (object) in amazon s3

Question

I have the option to upload files to Amazon s3 on my site. When the user downloads the file, I install acl using the function putObjectFile.

In EditMode: how to overwrite / update acl for a file that I am updating without reloading the file?

Is there any function that updates the acl of an existing file (object).

A solution is needed in PHP. Any links to sample code / or any other solutions are appreciated.
