mysql php insert update delete select rows using data services

Hi all,
My second post here, you folks helped me out with the first one :) thanks.
Now for my next problem, I am looking to use data services to insert, update, delete and select rows from a Mysql database. I know that you can use AMFPHP but I would prefer using data services. I have seen some examples of creating XML using PHP to display the data, but as yet I have seen nothing that allows you to save, update and delete the data.
If anyone has any pointers, I would appreciate it very much.
Thanks in advance.
